Deepcool is a popular cooling solution provider around the world. Founded in 1996 in Beijing, headquartered in Shenzen China. The specialized cooling solution provider, mainly focusing in Thermal solutions for desktop, laptop and servers. The Deepcool name was inspired by the Deep Blue, a supercomputer built by IBM for Chess game. An interesting inspiration though. The research team over Deepcool has been focusing on Computer CPU Cooling solutions, Video Card cooling, laptop and servers cooling solution. In addition, to proactively compete the market, they started working on AIO coolers, PC Chassis and Power supplies. The Assassin II CPU Cooler was got out in 2015 under the sub-brand of GamerStorm, and has been popular for it’s attractive look.
Today, I am taking a look at the Deepcool GamerStorm Assassin II CPU Cooler. The Assassin II is a 140mm heatsink Air cooler, comes in a fully modified Twin Tower. One of the great looking cooler, provides full support in heat dissipation by using 8 nickel-plated heat pipes and copper base. The Assassin II comes with 140mm and a 120mm fan having rated speed of 1400 and 1200 RPM, respectively. Having compatibility list of all Intel and AMD sockets, the cooler ensures 100% compatibility support across the platforms.
The package and the Content
The Cooler shipped in a premium looking black box, which is quite tall and seems to be huge for an Air Cooler. Very interesting to see that there is not much designing on the box, except the Deepcool logo and GamerStorm designed face. The branding line “8 Pieces of High Peformance Heatpipes” on extreme left tells quite a bit about cooler and its possible performance. The tone of color scheme is mostly the dark and aggressive.
On the backside, we have the GamerStorm logo on top left, Made by Deep Cool on right and just below to it, is the ASSASSIN II in fancy Green color. Coming down a bit, the socket compatibility list (includes Intel and AMD) and next to it, is the cooler’s major specification. The bottom tells the headquarter location and website. Beside it, we also see a white barcode sticker.
On one of the sides, the cooler’s major features are listed and define briefly. It has 8 pieces of U shaped copper heat pipes. Following the heat pipes, the Asymmetric twin tower design is highly optimized to provide efficient performance and nickel plated heatsink is one to offer gaming experience. Having mirror finished copper base, the nickel plated base help to absorb the heat rapidly. Finally, we see the cooler has two fans and both are manufactured with FDB bearings, which are popular for low noise performance accompanied with PWM function.
Inside the box, we found the accessories box, which is interestingly also black. Taking the box out and we see the foam systematic packing that covers the cooler from top. Interesting. We have a feeling that the team over DeepCool has overdesigned the packing stuff, since air cooler doesn’t need lots of packaging foam, and we are sure this would cost them quite a bit more. However, it’s a solid packing and nothing is better than product safety.
Now we dig inside a little more, we see the cooler itself is being sitting in comfort. We bring out the product and laid all the accessories on the table. The coolers caught our eyes at first glance. On the other hand, man o man, the accessories are in numbers. Not to mention they have included the fan hub in “Other accessories” plastic bag, that completely surprised me. Such goodies are always welcome. Even the No. 1 company doesn’t offer a good quality fan hub with the Air cooler. Honestly, in our experience Deepcool left behind the competitors, in this regard.

The Assassin II – A close Look
The Deepcool Assassin II is a Twin-Tower heatsink cooler that offers 140mm (rated at 1400RPM) and 120mm (rated at 1200 RPM) cooling out of the box. Looking at the cooler, the two radiators are built to effectively dissipate the hot air. It’s a nickel-plated heatsink being designed to work efficiently, and silver color scheme adds a good touch to an overall theme. The GamerStorm Logo appears on both the radiators, just close to heat pipes on tip. This is a solid design that we mostly see on the dual tower heatsinks.
The heatsink top has the heatpipe top tip emerged on top of the radiator. They all are not alike.
The rear side of heatsink looks formal with no noticeable gap between the fins. Honestly speaking, this finishing from Deepcool is absolutely fantastic. The one we have been tasted before, is on Noctua NH-D15S Air Cooler, which renowned as has the best finishing work to date. This, Assassin II, has extremely similar finishing.
Taking on the dimension, the heatsink alone is 158mm in height which offers comfortably fit in most mid-towers. The cooler has a width of 143mm, including the fans. The distance between the fins and copper base is 45mm, which suggests a 44mm RAM has no serious trouble sitting below the heatsink. That’s being said, there would be little trouble if you have RAM with heatsink having bumpy height.
Looking at the sides, the radiators have nickel plated fins and their construction is pretty good. The finishing work is top notch. Each tower has 48 aluminum fins and all have equal gap between them. A few of the fins at sides got slightly bent. This may be due to the tightness of clips on the fins. The fins from sides have a fair distance between each other, apparently, a nice, capable built to move away the hot air, generated from CPU and with the air moving at a rate of 70 CFM, the heat would easily kick outside.
Coming to bottom, The first thing we see is the Warning about Remove before installation on base.
The bottom reveals the Nickel-plated copper base, has the mirror finishing for high quality work. This nickel-plated copper base is shiny and looks beautiful that we can see a wall clock through it. About the effectiveness in thermal conductivity, the nickel-plated copper is not entirely subjective to the best in the area, but it’s quite effective for the task; the pure copper has much better thermal conductivity.
The Assassin II carries 8 high performances, Nickel-plated heat pipes which helps copper to absorb the heat from CPU and quickly dissipate it. The 8x U shaped heat pipes are nicely bent, goes through the copper base and then from inside of fins to top. The standard heat pipes are 6 and 7 for adequate heat transfer, which we have been seen in rival products, too, but interestingly, Deepcool gone with an additional to the standard one.
We also see a a barcode sticker having Warranty Void text printed on it.
The Assassin II came with 2x fans having red and black color combination. both the fans comes in a black and red color scheme. The The fans have Anti-vibration coating on the frame. which reveals splendid look. I must admit, th level of work is truly professional and extremely thougtful. The 140mm fans have total of 9 blades and build on a tremendous quality. We are extremely impressed with the dlievery of quality being done by the engineered over Deepcool.
One fan is 140mm with round shape design, top the speed at 1400 RPM (+/- 10) RPM. The fan takes about 1.32W on 12V. The fan has 70 CFM rated airflow rate. A 120mm fan included in the package works as the second fan for heatsink. having rated speed of 1200 RPM (+/-10), it ensures effective airflow should reach to the desired area without sacrificing on noise environment. Both the fans have FDB (Fluid Dynamic Bearing) and High-Quality ICs technology, which delivers extremely low noise behavior, is newer and reliable technology however with slightly shorter lifespan than the fan equipped with double ball bearing technology. The purpose of FDB is to minimized the noise and keep the environment noiseless. The fan offers lowest 300 RPM, thanks to PWM function for extensive speed control. The 120mm fan takes 1.08W on 12V. The rated noise in dBA for 140mm is 17.8 – 26.5 dBA and for 120mm fan, it is 17.8 – 27.3 dBA.
To begin with, we first setup the prior items i.e. motherboard and CPU. We are using Asrock Z170 Professional i7 Gaming. We readied the CPU on the socket by removing previous cooler and cleaning the old thermal paste.
Get started with mounting the back plate, which apparently black in color. We filled the 1151 compatible holes with Screw Bolt x4 and put the De-Vibration Buckle x4 in all the possible bolts. Yes, we know what are you thinking about these Buckles, but one thing is pretty certain that these buckles are extremely worthy here. These De-Vibration Buckles hold the Bolts tightly, which indeed is an impressive move.
When done from back. We moved to the front and pace up the installation by sliding in the Insulation Pillar A x4 on the Screw Bolts, firmly. For the first time installation, manual is helpful. We check some instructions and guidelines and headed towards the brackets. Now it is time to mount the Brackets (for Intel) x2 and Nut A x4 and then tightly screwed down the brackets by using a locally made screwdriver. We made sure all four corners have been tightly screwed and no loose ends on any side.
Time to surface the Assassin II on the CPU. The installation kit comes with a Retention Plate x1. We place down the Retention plate on the copper plate which met it’s one end with top bracket and other end has met to bottom bracket. Screwed it quickly with a screw driver and done.
Finally, we mounted the cooling fans one by one using steel clips, which apparently has a solid construction, too. These clips are of very high quality and even better than premium products, in this regard. I personally inspired with the quality of the cooler plus, all the things related to the cooler is absolutely top notch in quality and of course the looks.
The overall installation of the cooler is quite easy. It took a few minutes to figured out the right way to install via manual. There is not much to look at since the 115x kit is pretty easy and straight forward. We would rate it 9 star out of 10.
The final look on the coolers is fantastic and since the motherboard’s theme is also playing in red, those red fans are completely justifying the theme collaboration. We are proudly presents the Assassin II as the one of the best looking CPU Air Cooler to date. Maybe some of you thinking about the black fans, that are quite optimized to all themes, but we also know most motherboards offer red and black colors schemes (exclusives of purely dedicated single odd colors like Yellow and white), and this cooler absolutely perfect choice if you’re looking for matching scheme.
We also observed that Assassin II has an 8mm gap between the middle fan and the heatsink. Honestly, out of many Air cooler that we have reviewed, this sort of design has been encountered for the first time. We are not yet sure if such design effects the performance. Though, it sure looks nice and a stand out version.
The Assassin II cooler comes with extra accessories (other than the installation kit). The GamerStorm labelled fan hub that is meant for cooling solutions. So we tried this product and connected both fans with the Fan Hub. There are four headers on the fan hub and we connected on two headers I.e. 1st and 3rd. The fan hub’s connector has single cable, which is 4 pin PWM, connector to CPU_FAN to make the cooling fan works. As for control, though it has a 4pin PWM cable, it doesn’t have capability to control all the fan connected to the hub. So a white header appears in the hub, which offers controllable feature. There is a 3M sticker, which works as a glue for fan hub. So you may stick the hub on to the metal case, depending on your requirement.
Compatibility and Clearance:
The Assassin II cooler is meant to be used in every single socket released yet. Whether you have Intel’s oldest 775 or newest 1151/20xx socket (Skylake and onwards) all carries supportive brackets in the accessories box. Apparently, the Cooler has included the kit that offers AMD’s every single socket support and hence, Assassin II is fully compatible with sockets across the platforms.
Coming to Clearance and tolerance. The Assassin II is a Dual-Tower air cooler, which measured 143mm wide and that includes the fans as well. The cooler has full clearance to the RAMs, but it exceeds the DRAM slot a bit, which apparently hides one RAM (A2) completely and most part of second RAM (B2) as well. If you have all four slots populated with RAM, then that would also be hidden. Here, the idea behind showing off the beauty of RAM (RGB and Cold colors) is entirely being wasted just because of the wideness of cooler. This is one appealing attitude of this cooler, I must say. With that being said, even Noctua and other Dual tower coolers have the similar presentation.
We were very interested to see if the Cooling fan or the heatsink touches the RAM’s heatsink or not. We find that at stock placement, the cooling fan does permit 44mm RAM to be sit without obstructive behavior catches from top, although with 4pin cable touches the RAM. But that is futile, as you can always change the orientation of 120mm fan. Conversely, if you have even more heighted RAM, like the Corsair LED (49mm) or Dominator (55mm), which exceeds the 44mm height then you will need to raise up 120mm fan as according to the necessity. The gap measured is 4-5mm between the RAM’s heatsink tip and the cooler.
Note that we installed our RAM units in dual channel A2 and B2 after installing the heatsink and everything, which caused us a slight hassle. So take a piece of advice, install your dual channel memory kit before you done with cooler. On the other hand, Low profile memory modules are free from any hassle.
Afterwards, when we moved down to PCIe area, there was an adequate gap observed between heatsink and first PCIe slot. It’s approx. 23mm gap held between them, which is good enough for a back plated GPU to be installed on PCIe. So, from this angle, Assassin II is perfect.
The best thing is we already have the RGB fans which also offers the red color theme. So, with the combination of SilverStone FW142-RGB fan, specifically the Red color, this cooler has took over the charge and outcome looks extremely worth watching. Quite impressive, to say the least.

- HWiNFO64 5.30v
We took consumer grade processor from i7 range i.e. Core i7 6700K and plugged on ASRock Z170 Professional i7 Gaming motherboard to achieve some overclocking clocks for tests. Further, we utilized Noctua NT-H1 thermal paste application using “Dot” method technique. FYI, NT-H1 ranked in top thermal compound around. There are three Silverstone FW142 RGB fan running (Exhaust) in the case at a speed of 1500 RPM maximum and one Noctua NF-F12 3000 RPM on front (Intake).
We have used manual settings in BIOS on stock and overclocking clocks. The Core i7 6700K run at 4.0GHz (Stock) with manual voltage at 1.15 vCore in BIOS (1.184 vCore on Desktop) and OC at 4.5GHz vCore at 1.25 in BIOS (1.28 vCore on Desktop). With Prime95, we determined the temperature results at extra high load. This program tells the capability of CPU in stock and overclocked condition, of course under extra-normal loads. All the test ran long for 15 minutes, which is an adequate duration to probe and get satisfactory results.
We are using Also, we have used Delta temperatures (Ambient Temp – Reported Temp) = Delta T
This method is especially suitable for variable room environment.
We tested the Assassin II with alone and comparatively analysis. We took Idle and Load temperature figures and ranked them up in charts. The results are as follows
The idle temperatures at 4.0 GHz clock were sitting at 10°C and on load, it maxed out 31°C Delta T (originally reported was 63°C), while on overclocked clocks i.e. 4.5GHz at 1.25v, it maintained at 42°C Delta (originally reported 74°C) as the max reading being reported in HWiNFO64. Here, we can see the difference between the single tower Noctua U14S and Twin Tower Assassin II is 1°C on stock, which is marginal, but matters. On the other hand, it does manage to stretched the gap by noticeable figures to Noctua and Scythe; single Tower CPU Coolers. Additionally, OCed temperature tells a different story as the Celsius degrees is about 3°C better than the competitors, which is impressive. However, under our test procedures, Assassin II couldn’t come near to Reeven Okeanos in Celsius performance.
The Deepcool Assassin II is one of those CPU Cooler that offers highly flexible fan speed vai PWM equipped feature; to allow users to effectively control the speed of fan, which further mitigate the noise. Of course, users do love to have a silence environment because the higher the noise, more disturbance would be made in the quieter environment. The Assassin II at 100% fan speed does generate little noise but that’s only noticeable when you close down your ear on it. our experience tells, that still unnoticeable thanks to FDB technology that Deepcool has used in those fans. In our comparative analysis, the Reeven Okeanos was the noisiest cooler and Assassin II with two fans is far from actual hearing.
- Outstanding quality
- Excellent finishing
- Twin Tower performs Good
- Brilliant Showcase
- Full Clearance
- Red matches Gaming theme
- Hides RAMs outlook
The Deepcool Assassin II Air cooler has turned out to be one of the great looking product in the cooling category. The Twin Tower heatsink design offers extensive air cooling with the effective 1500 and 1300 RPM (being reported in software), helps dissipating the hot air quickly. There is no doubt that a single tower CPU Cooler is most compatible and fine looking coolers, but GamerStorm’s Assassin II on the other hand, has one of the best finishing as a whole. And If we had to compare the finishing work with any other cooler, we’d choose Noctua D15S (not present in comparison). Honestly speaking, we are leaning more towards Assassin II now, well, not because it is here for review, but the theme presentation is actually very impressive, especially when you have or opt for red themed gaming rig. The 8 heat pipes design is a noteworthy here, is quite effective and not to mention nickel plated copper base has a mirror finishing is truly amazing piece of work.
Performance wise, Assassin II is a very good against the popular single tower coolers. In our observation, the heatsink has offered much better performance delivery, especially in high overclocking situation. The max reach up point is 42°C, which turns out to be better than what competition has manufactured. However, under our testing procedure, we encountered a quite noticeable Celsius difference between Twin Tower Deepcool Assassin II and the competitor Reeven Okeanos RS 1402. Except for this, Assassin II has done marvelously great. The noise operation in addition is fairly good. Nothing that we could hear from sitting closely to the system with even fans running at 100% speed.
Among those likings, we still have one disliking about this cooler, is the RAMs being hidden under the cooler. The cooler is 143mm wide, which covers all DRAM Slots hence, kills the purpose of Showcasing RGB/LED Memory modules. Optionally, you can remove the fan, but that would affect the performance and kills the beauty of cooler outlook. It’s typical in Twin-Tower Coolers, so whichever cooler you go with; the same dilemma would come across.
Selling at $99 US Dollar (at the time of this review) on Newegg. The cooler has a marvelous look especially for red theme lovers. The cooler comes with bundle of accessories and not to mention the fan hub, in generosity. With being offering full compatibility support to across the sockets on INTEL and AMD, the cooler is future proof across the platforms. Therefore, if you’re not worried about the RAM beings hidden, then DeepCool Assassin II Cooler could be a fantastic upgrade for your new gaming build.
