We haven't tested systems for a long time air cooling, we are correcting, within the next month there will be several interesting reviews... We'll start with a novelty Deepcool ASSASSIN II, sales of which will start soon in Russia with a recommended price tag of 6,000 rubles. ASSASSIN is flagship model with the line of this manufacturer, it will have to squeeze the top solutions of competitors on the market.
As part of the "Laboratory", examining coolers from this manufacturer, they noted good value cost and performance. They are available to the mass buyer, the arsenal has systems for different types systems ranging from the smallest to the most powerful gaming. The second generation of ASSASSIN is the expected continuation of a successful series. All the advantages have been preserved, the disadvantages found have been corrected. Now the "tower" has become asymmetric, the quality of the complete fans has been improved, and the weight of the structure has been increased. What can boast of new flagship, we'll see during testing.
Video review Deepcool ASSASSIN II
Equipment
Deepcool ASSASSIN II is delivered in a massive black box with a handle for transportation. Appearance packaging design is typical for the Gamer Storm line.
Of the useful information, it is worth noting the enumeration of the supported AMD sockets and Intel. These are all common sockets today. Only the dimensions of the system itself will become a limiting parameter.
The complete set includes all required set fasteners, a backplate board, a tube of thermal paste, an extension cable for connecting fans, a sticker on the case, assembly instructions and a set of technical documentation. The kit contains everything you need for assembly and installation. The fans are initially installed on the cooler.
Appearance
Deepcool ASSASSIN II gained weight, now the total weight with installed fans reached up to 1.5 kg.
The tower structure has shown itself well in those situations where it is required maximum efficiency from air cooling. The second generation has preserved general principles designs, but now the design is asymmetric. It will not work to choose the side of installing the fans, as well as add a third one.
Above I mentioned the dimensions, now they are 160x144x154mm with installed fans.
It consists of two sections with aluminum plates, a total of 49 on each side. Connects this entire array of 8 copper 6mm nickel plated tubes. Plates are pressed for better contact with tubes. The distance between the plates is 2 mm.
The optimum distance ensures efficient airflow. The thickness of the plates themselves is 0.5 mm. General effective area is 12100 cm2.
A 140 mm fan is installed between the two sections, fixed with brackets. The inner part has vertical grooves, this is not a decoration, so the airflow movement is improved.
The outer walls also have a jagged design, they look impressive and original.
The tubes are pressed into the base of the Deepcool ASSASSIN II, which consists of two nickel-plated plates. Outside surface with a perfect mirror finish. The area is sufficient for effective contact with heat spreader cap from Intel and AMD.
Installed two fans with different standard sizes, inside - 140 mm, outside - 120 mm. Fans with red blades, rubber casing and notched blades.
The second generation is quieter, in part due to lower revs, while maintaining performance. Fans are secured with wire brackets.
Installation
The assembly mechanism does not differ from other Deepcool towers, we have already examined it in detail. Initially, you need to apply thermal paste to the processor cover, in an even layer. We assemble the backplate plate by installing the bolts in the required hole. There are markings on the inside. The bolts are fixed with rubber pads.
After installing the plate, it remains to fix the two metal plates from the front side by tightening the screws.
It remains to install Deepcool ASSASSIN II and tighten it with a pressure plate, two bolts. For convenience, you will need to remove the internal fan. The assembly is simple, the kit contains detailed and visual instructions.
Testing
Deepcool ASSASSIN II looks massive, it completely covers the connectors random access memory... Most of the RAM strips will do, although now it's not a problem to find adequate solutions with compact heatsinks. In the future, to dismantle the memory strips, you will need to remove the fan or cooler case.

Results for Deepcool ASSASSIN II
Deepcool ASSASSIN II has demonstrated high performance. It can be viewed as perfect solution for gaming systems, for overclocking and for those who are used to squeezing the maximum performance out of the processor used. The design update was successful, the system became quieter, operating temperatures were lower. The pluses include support for all common Intel sockets and AMD, a smart package. I liked the reliability of the fastening and the ease of assembly. Not without its weaknesses: difficult access to memory sticks, as well as cost. Deepcool ASSASSIN II receives an award "Gold..
Company Deepcool is undoubtedly one of the leaders in the design and manufacture of air cooling systems for personal computers. The products of this manufacturer received great popularity and distribution among users mainly due to their low cost. And like any self-respecting company, Deepcool should have its top product. Designed to emerge in the air cooling market as a super cooler battling leading edge solutions from competing manufacturers. Deepcool assassin belonging to the GamerStorm line.
Packaging and equipment
Supplied "hitman" in large black cardboard box... Packaging design is not typical for Deepcool products
The play of white and green colors of the design on a black background is well chosen, which gives the product a kind of charisma
The back of the packaging is the specifications of the heatsink, fans, and a list of supported platforms. By the way, you can put Deepcool Assassin on any of the modern AMD or Intel platforms. Great compatibility the cooler is obliged to a set of proprietary mounts included in the kit.
The weight of the cooler together with the packaging is almost 1.5 kg, so the manufacturer has provided a plastic handle on top of the box to transport such a purchase. The country of origin of the cooler is China.
The package includes a radiator, two 120mm and 140mm fans, a user manual, a set of mounts and accessories.
Other accessories include an unknown manufacturer of thermal grease, a plastic GamerStorm logo and fan adapters. Moreover, one adapter allows you to connect both fans to one 4pin connector on the motherboard, and the second will allow you to connect the fans to the molex connector with a 7V voltage supply.
Design features
As practice shows, a tower structure with two sections of radiators is now half the success. air system cooling. Deepcool did not experiment either, building their super cooler along the way already proven by most manufacturers. The two-piece Deepcool Assassin radiator weighs 1070 grams.
The two radiator sections are interconnected by eight nickel-plated heat pipes, each 6mm in diameter, that pass through the base of the heat sink. The cooler is not as big as it seems, its dimensions together with the fans are 160x144x154mm.
Each section of the radiator has 49 aluminum fins, which are pressed onto heat pipes. The plates sit on the heat pipes quite tightly and evenly, despite the fact that soldering is not used at the joints of the plates to the heat pipes. 
The intercostal distance of the plates is 2mm, which is the most optimal value to build an efficiently cooling radiator.
Both sections of the radiator contain a total of 98 plates with a thickness of 0.5 mm. The processing of sharp edges of the plates cannot be called ideal, so it is very difficult to cut yourself with them.
The total area of the "assassin's" radiator is 12100 cm 2. Between the two sections of the radiator, a fan with a standard size of 140x140x25mm is provided. The distance between the radiator sections is 28mm.
Eight heat pipes are located sequentially along the length of the radiator section, at a distance of 12 mm from each other. The inner walls of the radiator sections have characteristic triangular vertical grooves to optimize airflow.
The outer walls of the radiator are pyramid-shaped to give the radiator a more attractive appearance.
The base of the heat sink is protected by a transparent plastic cover.
Eight nickel-plated tubes allow you to hope for success in the efficiency of the cooling system even before testing.
The base of the heat sink consists of two nickel-plated copper plates, between which the heat pipes are clamped by pressing. There is no soldering at the outlet of the heat pipes from the base.
The workmanship of the nickel-plated base is not good enough, it is amazing. Dimensions (edit) contact pad are 60x45mm, which will be enough not only for AMD processors, and for Intel processors performed by LGA1366 and LGA2011.
You cannot make any serious claims to the evenness of the surface. If even along the length of the contact pad you can observe a barely noticeable bulge, then along the width you can see a perfectly flat surface. The quality of processing of the base and its flat surface also give hope for good heat transfer, and therefore effective cooling.
Active cooling of the Deepcool Assassin radiator is performed by two UF140 and UF120 fans, with a standard size of 140mm and 120mm, respectively. Distinctive feature for these complete fans the impeller is green. For those who do not like the "green", the manufacturer offers the same coolers, only in a blue color. Both fans have anti-vibration coating to reduce noise. The UF140 fan has a 120x120mm mount, which allows Deepcool Assassin to be equipped with brackets for complete fans of the same size. The 140mm turntable is PWM controlled, which allows the fan to operate between 700 and 1400 rpm. The resulting air flow is 80.28CFM, and the noise level is 18.2-32dBA. The younger 120mm fan is content with only a 3pin connector, and therefore operates in a fixed mode of 1200 rpm. The airflow of this turntable is 52.35CFM, while the noise produced is 23.2dBA. Both fans are hydraulic bearing based. 
The raised notches on each of the fan blades are recognized for creating visual effect while the fan impeller is rotating.
General view of Deepcool Assassin with UF140 and UF120 fans installed. Fans are attached to the radiator of the cooling system using wire brackets. In our case, we decided to install the 140mm fan just outside, as this gives the cooling system a more effective appearance. The entire assembly has a total weight of 1378 grams. Recall that the Thermaltake Silver Arrow SB-E Extreme we reviewed earlier, together with the fans, weighs only 1100 grams.
Installation
Considering the procedure for installing the Deepcool Assassin cooler, we use the Gigabyte Z77-D3H Socket 1155 motherboard, Intel Core i7-3770k processor and 4 Hynix DDR3-1333 4Gb RAM modules as test components. The installation method is standard for such cooling systems. " caliber ", but so that you don't have any problems, we will describe the process. First of all, we open the socket contact pad and remove the protective plastic plug from there.
Then we install a processor in the socket, in our case it is the i7-3770k, which has been a permanent component of our test system for a long time. You also need to apply thermal grease to the processor. In our tests, our i2Hard edition uses the GC-Extreme thermal interface from Gelid.
The next step is the preparation of the backplate (metal plate) for installation on the motherboard.
On the backplate there are Roman numerals for the holes corresponding to the sockets, and in the middle of the plate itself there is a decoding. In our case, these are holes with the number II.
We insert the threaded bolts into these holes and fix them with the special rubber inserts that come with the kit.
Then we install the plate onto the motherboard.
We dress on protruding from motherboard bolts black plastic washers.
We put two metal plates on top of them.
Then we fix them with four nuts. Everything, the fasteners are ready. Then all that remains is to put the cooler on and fix it with a pressure plate with two bolts.
Appearance on the motherboard
The Deepcool Assassin cooler installed on the motherboard looks very massive and covers all four slots for RAM in size. But do not rush to be upset. After all, a huge plus of fastening the fans, the fixation of which on the radiator is made with the help of metal brackets, is precisely that these same fans can be slightly raised in height, by about 10-12mm.
This can be clearly seen in the photo below. At the maximum lift of the fan installed from the outside, the memory modules feel quite at ease, and there is even some margin above them. free space... Therefore, when buying Deepcool Assassin, you can not be afraid of incompatibility with RAM modules. The only exception should be considered memory modules with high heatsinks.
In our case, when the fan was raised to the limit, the space around the socket lost its airflow. Therefore, we lowered the cooler back a little so that it rests against the memory modules. This made it possible to direct part of the air flow to blow off the space around the socket.

Overclocking the processor to 4.5GHz required an increase in power supply, and, therefore, increased CPU heating. In this mode, Deepcool Assassin loses its ground a little more. The difference between it and the Thermalright Silver Arrow SB-E Extreme is 6 degrees Celsius in load. It is worth saying that given the hot temper of Intel Core i7 processors on the core Ivy bridge, and here both coolers show quite good results. 
Conclusion
Deepcool assassin- the cooler is really solid from all sides. It goes without saying that this is not a product-killer of top-end cooling systems from other manufacturers. The "Assassin" just slightly lacks the cooling efficiency for this. A plus Deepcool assassin in its value. With an average market price of 2300 rubles, this cooler not only surpasses similar solutions from other companies, but becomes an attractive target for economical overclockers and ordinary users. Pros:- massive two-section radiator with a large heat transfer area;
- good cooling efficiency;
- convenient mount;
- excellent processing of the base;
- the possibility of installing a third fan;

Deepcool Gamer Storm Assassin II Review | Design features and specifications
Deepcool releases a new air cooler not every day top-level... More specifically, the first Gamer Storm Assassin model we tested about three years ago... However, having received it for tests, we had to put it on the shelf. At that time we have already done Review of the Fresh Deepcool Closed Loop Liquid Cooler(English). In addition, there were many products for the Z170 chipset marked "urgent" in the queue for review. Perhaps some of those new products could wait.
Deepcool Gamer Storm Assassin II can easily cope with the moderate temperature requirements of Skylake and, it seems, is ready to compete with the leading coolers in cooling overclocked Core processors i7 based on Haswell-E microarchitecture. Almost 1.5 kilograms of copper is a serious challenge for enthusiasts, and although the cooler fits smaller sockets, we just didn't dare to install it on a small and light motherboard.
Deepcool Gamer Storm Assassin II fits almost any CPU socket except AM1, which generally does not require fans to maintain low temperature with a radiator of this size. Dedicated stands are compatible with LGA 2011 mounting bracket (including v3). The universal base plate has retention studs that protrude from the back of the board with a square Intel ILM and a rectangular AMD mount. The cooler's contact pad is pressed with a transverse bar. Users AMD boards you first need to remove the cooler mounting bracket to expose the four mounting holes on the board. Naturally, the cross bar must be installed over the base of the cooler, and you can get to it only by removing the central fan.
For optimal contact between the processor and heatsink, Deepcool polishes the base of the cooler and then nickel-plates the copper to prevent oxidation. The reflection of the logo on the surface of the contact pad shows how smooth it is.
We installed a 120mm fan in the front and a 140mm fan in the middle. They come with a radiator. The center fan has primary status as the front fan can be removed to increase space when installing components. We decided not to install the spare fans that Deepcool sent with this cooler as they are not part of the standard kit. A splitter for four fans is included as standard, but if used, we cannot get separate rpm readings for the two fans.
If you are not sure what Deepcool Gamer Storm Assassin II will fit into your case, we recommend that you familiarize yourself with the technical characteristics that we have given below.

Deepcool Gamer Storm Assassin II Review | Test results
With cooler Deepcool Gamer Storm Assassin II at full speed fan rotation CPU temperature and PWM is two degrees higher than with the famous NH-D15. Temperatures at lower RPM are slightly worse, but this is because the Assassin II fan profile was manually set to 50% and the NH-D15 fan speed was well above 50% of nominal.
Temperature above ambient
The fan speed graph shows that cooler Noctua reduces speed by about 25%. We used proprietary high resistance wire, assuming that Noctua knows the "optimal RPM level" for efficiency. Meanwhile, coolers that do not have this feature operate at "not optimized" settings at the 50% level. Does this make sense?

Deepcool Gamer Storm Assassin II Review | Conclusion
Deepcool Gamer Storm Assassin II It falls short of the level of top-end air coolers for CPUs in terms of cooling efficiency, but its price is low enough to provide it with a more attractive efficiency-to-cost ratio. That doesn't mean it's cheap, it's just that it's cheaper than the best CPU coolers we've tested.
Some users will like its appearance, and the additional 15 mm of space on all sides of the cooler, available by reducing its dimensions, will allow this model to be used in more motherboards and cases. But to give this cooler a reward, only a more attractive price-to-performance ratio is enough.
Unfortunately, our experience of installing heavy coolers on four-layer motherboards suggests that it is better to limit the use of a giant weighing 1417 g stationary systems with six-layer motherboards. However, this range covers most models of boards with LGA 2011 and LGA 2011-v3 sockets. However, the range of supported connectors Deepcool Gamer Storm Assassin II much higher. If you have any doubts about installing this cooler on your board, it is better to consult the users on our forum.
Advantages:
- Excellent cooling performance
- Relatively low price
- Relatively low noise level
- Leaves more free space on the sides
- Higher price / performance ratio compared to top-end models
Flaws:
- Heavy weight
Conclusion: Deepcool Gamer Storm Assassin II for $ 80 is a rather expensive cooler, but in terms of its characteristics it surpasses the most famous rivals.
Friends, today I will tell you about a rather interesting supercooler made by the company DEEPCOOL... Although this is no longer a novelty, the model has not lost its relevance to this day. It is possible that someone has not heard of him yet and the material will be useful for him.
Released in 2015, ASSASSIN II became one of the best among tower supercoolers, showing decent result in terms of cooling efficiency, which has been proven more than once. The issue of price is also important here - DEEPCOOL was able to establish an acceptable price tag for many, which made it possible to compete directly with such giants as Noctua and Thermalright with their NH D14-D15 and Silver Arrow.
This model has enormous potential and its place is clearly not in the average configuration, but in the PC of a computer geek who is not by hearsay familiar with such an option as "CPU overclocking". All in all, let's see how good DEEPCOOL's Killer is and is it really worth the money?

Packaging and equipment
The ASSASSIN II is delivered in a black cardboard box. On the edges there is a description of the main features of the cooler, and also lists its TX.
The package contains: a two-section radiator, two fans, documentation, a set of mounts for installing a cooler on AMD and Intel platforms, a brand badge, a tube with thermal paste, and a hub that is used to connect several fans to one channel.
Appearance and features
The assembled structure looks very massive, and its weight is considerable, almost 1.5 kg. The fans are attached to the radiator with metal brackets. Simple and convenient solution... The overall appearance is pretty, the combination of silvery shiny surfaces with black and red looks beneficial.
As you probably already noticed, the fans are of a different standard size from each other. One of them, enclosed in a standard square frame, has dimensions of 120 x 120 mm, and the second is 140 x 140 mm. Both fans belong to the GF range. The frame of this series of fans is covered with TPE-material. And again, the possibilities of modern polymer chemistry are in action. The material has a number of properties that help to damp the vibrations generated by the fan as much as possible. It is also worth noting the elasticity of the material, ordinary "oak" plastic is very easy to break, for example, by pulling the mount, in the case of these fans such an annoying situation is excluded. The second feature is the grooves on the blades, which optimize the airflow generated by the fans. The third is a collapsible design that makes it easy to clean the blades, for example, from dust. Well, getting to the "insides" becomes much easier, which will allow you to easily lubricate the mechanism. Due to this design, the mechanism itself, in addition to being protected from the effects of dust and moisture from the outside, has a reverse protection against leakage of lubricant. Both fans have a 4-pin header, which means both fans are PWM controlled. The rotation speed of a 120 mm fan impeller varies within 300 ± 150 ~ 1400 ± 10% rpm, while for a 140 mm fan the performance is slightly different and amounts to 300 ± 150 ~ 1200 ± 10% rpm. In both cases maximum level noise does not exceed 27.3 dB (according to the manufacturer), which is good news.
Now let's take a closer look at the radiator. 8 nickel-plated copper heatpipes with a total of 96 aluminum fins strung (48 per section). The distance between the plates is ~ 2 mm. It is worth noting that the plates are in contact with the tubes without soldering, as is done, for example, in the Noctua NH-D15. For fans of RAM modules with high heatsinks, it will also be a "bummer", since the distance between the bottom point of the cooler base and the bottom aluminum plate is only ~ 45 mm. Considering the size of the cooler, the memory slots closest to the socket will definitely be blocked by it and only low-profile modules will fit in there without any problems. Further, I will note a slight inward bend in one of the sections relative to the other - this is not a defect, but a well-thought-out solution that allows you to optimize the air flow that cools the radiator fins.
The plates on the sections have a difference in structure, which is clearly shown in the photo below.
Let's move on to the base. It consists of two copper plates with a nickel-plated coating, between which heat pipes are clamped. There are no visible traces of soldering or heat-conducting glue, so which method is used remains a mystery. The base is even, without drops and bulges. Carefully processed and polished, it boasts a perfect mirror image... The print test confirms the flatness of the base, the paste is evenly distributed over the entire area, and the excess has been squeezed out, which can be seen at the edges of the print.

Installing a cooler on test platform not complicated by installing a backplate. We screw 4 double-sided bolts into the near-socket mounting holes.
We fix 2 metal plates on top of them and tighten them with knurled nuts.
We apply thermal grease to the processor cover, place a heatsink on top of all this and press it down with a metal plate with two spring-loaded screws. We fix the fans on the radiator with brackets.
Testing
ON LinX AVX 0.6.4 used for CPU load, task size value is 25000, load duration is 30 minutes. To fix the temperature of the nuclei, we used software CoreTemp.Testing was carried out in the above test configuration, thermal paste was used as a thermal interface Arctic Cooling MX-2... Ambient temperature at the time of testing was 24-25 ° C. The testing section is divided into two approaches. The first approach is to find out the maximum capabilities of the tested instances, while systems generated No attention is paid to cooling noise. The second approach is to find the most comfortable noise characteristics test instances followed by load repetition and fixation maximum temperature processor cores. The diagrams below show the minimum / maximum temperatures (° C) of the processor cores in idle and load, respectively. The opponents will be several liquid cooling systems and tower supercoolers. All cooling systems, except for the Corsair H110 (fans were replaced with Noctua NF-A14 FLX), were tested with standard fans. All LSS pumps operated at maximum performance.
Approach # 1
DEEPCOOL ASSASSIN II performed well. Among the presented tower supercoolers, it justifiably occupies a leading position. Of course, he is still far from the top-end unattended LSS, but given the price, this is clearly a good option. Yes, and the fans cannot be called noisy, for the same Corsair H100i the fans make such a noise that you can even hear it from the next room through a closed door.
Approach # 2
V quiet mode the situation does not change. To achieve perfect silence from this cooler, a slight decrease in the fan speed was enough. That is why the result "before" and "after" does not differ much.
Conclusion
DEEPCOOL ASSASSIN II is a great solution for high performance configurations. It will cope with cooling of overclocked processors without any problems, while doing everything without unnecessary noise. The model has many advantages, but it has not been without a drawback. In my opinion, the main and only one of them is that the radiator overlaps the nearest RAM slots, which excludes the possibility of installing modules with high radiators in them. With a stretch, one can also say about the height of the structure, but almost all such top-end solutions have ± a similar height. Now you can find this cooler for 3.5-4 thousand rubles, which is against the background of the same Noctua NH-D15, the price of which is at least 1.5 times higher - just like a god.Pros:
High efficiency;
Good complete fans;
Equipment;
Quality manufacturing;
Price.
Minuses:
Overlapping the RAM slots closest to the socket.
Thank you for your time and see you soon!

I first thought about replacing the processor cooler when I overclocked my Intel Core i 5-4570K to 4 GHz - after twenty minutes of running around in Battlefield 4, the game began to slow down. After three hours of checking the operating system, I guessed to look at the temperature of the video card and processor. It turned out that the regular box cooler intel brought the percentage to 95 degrees, after which he dropped the frequency from 4 GHz to a ridiculous 1.2 GHz - throttling turned on. The computer worked fine at the nominal frequencies, but once in the car there was weakness, it must be eliminated.
The current prices for components make you tense. The Noctua brand recommended to me was discarded immediately - in stores they cost almost 7 thousand rubles. As an alternative, I chose DEEPCOOL Assassin II, the first version of which, according to reviews on the Internet, was on par with Noctua, and at the same time cost almost half the price. I managed to grab the device for less than 4 thousand rubles.
The Assassin II is a tower model with heat pipes and two fans. A quick look at the manufacturer's website showed that the second version of the "killer" seems to have become quieter without losing the cooling efficiency. I don’t know what the first Assassin was, but when I was given a box with it new version, I got a little scared. It seems that in such a huge package is hidden a soccer ball or a bottle of whiskey.
Inside there was a radiator with fans and several bags with accessories. First, they drive you into a stupor - somehow there are too many metal strips, screws and bolts. In addition to the DEEPCOOL mounting system, we attached a splitter for connecting several fans to one connector on the motherboard, as well as a syringe with thermal paste and a sticker with its logo. The complete instructions are a must-read, as not everyone will be able to install the cooler correctly the first time without it.
The Assassin II itself is a huge bandura consisting of eight heat pipes with threaded radiator grilles. This is a time-tested design, which is now used to build all coolers that are more expensive than twenty dollars. According to the specifications on the box, the Assassin II measures 143x158x167 mm and weighs 1479 g. One and a half kilograms! Thermaltake Volcano 7+ was the heaviest cooler in my childhood, it weighed 680 g and was considered even dangerous for many motherboards.
The heat pipes in Assassin II are, of course, copper inside. But on the outside they are plated with nickel. Why, if nickel, unlike copper, has mediocre thermal conductivity? They write that a nickel layer in a hundredth of a millimeter protects copper from oxidation, and also adds presentability to the radiator. And such a small layer thickness does not affect the cooling efficiency. Eight heat pipes are strung with aluminum fins with a fashionable chopped profile. The radiator looks very attractive in general, unlike many analogs with ordinary rectangular fins.
The heat pipes do not adhere directly to the processor, but through an additional nickel-plated base, polished to a mirror shine. Absence direct contact- not a big deal, the thermal cover of the processors is still less than eight pipes. If there were no additional base, then the extreme heat pipes would remain without contact with the CPU, which means that the efficiency of the cooler would be lower than projected.
The radiator is cooled by two 120 mm and 140 mm fans, each of which has adjustable speed rotation from 300 to 1400/1200 rpm. It is selected automatically depending on the settings in the computer BIOS. The turntables are made in red and black colors and have a relief pattern on the blades, which should reduce the noise level with the help of some cunning aerodynamic magic.
The cooler is attached to the motherboard with a backplate. It acts as a stable base, to which two frames are fastened with screws on the front side of the board. And now a radiator is attached to them with a pair of thumbscrews. The mounting system is compatible with all current sockets of Intel and AMD processors, including such rarities as the LGA 775. By combining various complete frames and screws, you can assemble a mounting system for any socket, but be sure to look at the instructions so as not to mistake the holes in the backplate.
Very important point- the cooler completely covers the RAM slots on the motherboard, so when assembling a new computer, you should take care of the memory in advance. There were no other problems in my SilverStone Raven 2 case. But in small cases such as Mini-ATX, the cooling system can feel uncomfortable, up to conflicts with the power supply or the side removable cover of the case.
After turning on the computer, the fans first started working at full speed, and then dropped the speed to minimum - this is a feature of the motherboard, which always feeds to cpu cooler maximum voltage... While the computer is idle, Assassin II is inaudible. Box cooler Intel also worked silently, but cooled accordingly. Therefore, for testing, I again overclocked the Core i 5-4570K to 4 GHz, turned on the Core Temp temperature monitoring program and went to play different games.
In idle, the temperature of the overclocked processor fluctuated around 31-32 degrees, which is 7 degrees higher environment... Battlefield 4 and GTA V heated the CPU to 60 and 64 degrees, respectively. At the same time, the system worked stably, the FPS in games did not fall. Let me remind you that in the same mode, the last cooler gave out 95 degrees, and the processor sharply reduced the frequency. The maximum that I managed to achieve with the Assassin II is 75 degrees in a special test for warming up the Prime 95 processors. But this is a "synthetic" test, in reality a similar load on the CPU is unlikely.
As for the noise, there are no complaints about the device in this regard. During games, the cooler of the video card blocked out all other noises with its howl, I could not isolate the sound of Assassin II in the general cacophony. Only when running Prime 95 could rustle be heard, since the video card was not involved in this test. At maximum revs, the Assassin II does not bother - the noise is small and neat, even, without an unpleasant howl. Thank you hydrodynamic bearings fans.
DEEPCOOL Assassin II proved to be worthy. With a reasonable price, he easily coped with the overclocked processor, not a single popular game was able to warm up the CPU even to 70 degrees. At stock frequencies, the Intel Core i 5-4570K should be even colder, and the Assassin II revs, respectively, even lower. Potential is felt in the cooler. It remains only to decide how to open it - by overclocking the processor or simply demonstrating a beautiful gaming system through the transparent window of the case.
