Deepcool Gamer Storm Assassin CPU Cooler Review

Posted by on Sunday, June 23, 2013 - 10:05pm

What made us say the two coolers are direct competitors? Well, they are both dual-tower coolers but they both have a different fan mounting style used for cooling or to dissipate heat away from the fins. We are in favor of the Deepcool Assassin cooler from the start because of the fact that it offers a quieter operation in PWM mode as well as all out full speed.

Deepcool Gamer Storm Assassin CPU Cooler Review


Today, we will be taking a look at our second CPU cooler from Deepcool. That cooler would be the Deepcool Assassin from their new Gamer Storm product series that aims for enthusiasts. This particular cooler is one of the biggest offered by Deepcool. From the looks of it, it should be a direct competitor to the Silverstone HE01 which we also reviewed not too long ago.

Twin Tower Heatsink
The twin tower heatsink sets provides more heat dissipation area than traditional heatsinks. More than 2 fans can be mounted on the heatsink sets to achieve extraordinary cooling performance. Shark teeth fin design not only advocates aesthetics of heatsink but also allow better air conduction between fins. The whole heatsink sets are nickel plated for appealing appearance and also for gaming spirits.

8 pieces of U-shaped Heatpipe
Eight pieces of high cooling performance copper heatpipe ensures the best cooling effect for the processor. The heatpipes are scientifically bended to achieve optimal balance with the heatsink fins.

Mirror Finished Copper Base
Eight heatpipes are firmly soldered onto the copper base to enhance the heat conductivity from the processor to the heatsink. For the quickest heat transfer, the copper base has been CNC machined to extremely flat, just like a mirror.

12+14cm De-Vibration TPE Cover Fan
De-vibration TPE cover is a soft and elastic material which can absorb the operating vibration and noise maximally. Assassin equips with one 120mm and one 140mm fans to fulfill your harsh cooling requirement at lowest noise.

Closer Look

The Deepcool Assassin takes the concept of a lightweight cooler and throws it out the window. With the fans included, the total weight of the Assassin come to a hair over three pounds. To remedy the stress this amount of weight would put on a motherboard, Deepcool does offer a nice mounting system to ease any worries. At 5.6” x 6.0” x 6.3” for the measurements (with fans), we were firm to believe that the cooler will have no issues in mounting it on to our X79 motherboard.

The dual-tower style isn’t something new to processor cooling. We have seen many coolers in the lab with the same configuration with the last being the Silverstone HE01 but the most popular is perhaps the Noctua D14. But so far this style of air-cooling has resulted with the best operating temperatures.

The inside sides between the two towers have a really aggressive look. This design right here not only for styling but also to aid in heat dissipation. With the edges not being flat, heat is offloaded at different locations. It also aids in making the fan stay in place. We all know that vibrations can slightly adjust the placement of the fan even when it is secured using the wire clamps.

The opposite has the same heat dissipation effect but with a different pattern.

Each side of the towers are closed off to keep air produced by the fan blowing over the fins and not out to the sides.

The Deepcool Assassin cooler uses a total of eight 6mm heat pipes to transfer heat away from the base. The heat pipes are all nickel-plated to keep the aesthetics of the cooler shiny and appealing.

Unlike many coolers on the market, the Deepcool Assassin does use the heat-pipe direct technology in the base. The base is a solid piece of copper layered in nickel and it is very shiny and smooth.

Deepcool uses an odd combination of colors on the fans mated with the Assassin which are black and an olive green. Honestly, I don’t think it is bad at all. The fans are in two different sizes: 120mm and 140mm. The smaller fan of the two has a default rotation speed of 1200 RPM while the 140mm fan ranges from 700 – 1400 RPM because of the PWM function. Surrounding the frames of the fans is a rubber coating to help with vibration and noise.

Mounting support comes in the form of Intel sockets ranging from 775 up to 2011 and all existing AMD sockets.

Mounting Images

The mounting of the Deepcool Assassin isn't that difficult at all. We just suggest to do a pre-fitting of the motherboard brackets to make sure you get the cooler facing the way you want it to. The way they are in the first image, the cooler’s fan would be blowing from the middle of the motherboard to the top of the case.

Testing Methodology

For our testing we will be using the following procedures and parameters to acquire the necessary data:

  • Thermal compound used is Arctic Silver 5
  • Idle temperatures are recorded after the system has been allowed to idle for thirty minutes from the point Windows has finished loading.
  • Load temperatures are recorded by running OCCT for twenty minutes on all available threads.
  • Real Temp is used for the recording of all temperature sensor reading.
  • PWM function is disabled via BIOS to allow the fans to run at full speed.
  • CPU model and overclock speed used for testing are outlined below in "Test Hardware".
  • Each cooler is first tested with one fan supplied from the manufacturer.
  • Each cooler is then tested again with a second fan attached if provided by the manufacturer.

Test Hardware:

1. ASUS X79 Deluxe Motherboard
2. Intel Core i7 3930K Processor
3. Kingston HyperX 1866 DDR3 16GB
4. Kingston V+ 200 120GB Solid State Drive
5. ASUS BC12B1LT BD-Rom Drive
6. Thermaltake Frio Extreme CPU Cooler
7. MicrocoolBanchetto 101 Open Air Test Bench
8. Silverstone Strider Gold Evolution 850W Power Supply
9. ASUS Nvidia GTX 560Ti 448 Graphic Card




When it comes to the Deepcool Assassin cooler, we have to say it is one of the better coolers we have tested this year. Ranging in the top half of thermal results, we loved how well it performed with our overclocked i7 processor with added voltage. One particular advantage it has over the Silverstone HE01 cooler that we compared it to earlier in the review is its noise level. Flipping the switch on the HE01 to ‘Performance’ made for a significant increase in noise we observed. With the Deepcool Assassin running at full speed, we did hear it moreover the GPU fans but it was no contest, the Assassin was simply quieter.

When it comes to air-coolers, companies are trying numerous ways to make their cooler stand out. Deepcool didn’t do it with a fancy thermal coating or super large fans but was tackled from a visual aspect. The overall shape of the fans is a little aggressive but not over-the-top. And the sharp ridges do serve a purpose of helping with heat dissipation as well as added aesthetics.

The biggest knock against the Deepcool Assassin would be its sheer size. This is a non-issue with the overclockers and serious enthusiasts because they know what they are getting into with such a cooler. But for those that are not much of a system builder, it would bring us up to the fact the cooler interferes with the usage of memory modules with tall heat spreaders. Fortunately, we had no issues with our X79 setup.

Looking at the prices of many of the AiO water-cooling kits and some of the higher-end air-coolers, the Deepcool Assassin is priced pretty decent at around $80.
