Gamer Storm Assassin CPU Cooler Review

Hardware Secrets Golden Award

The Assassin is the first CPU cooler from Gamer Storm, a brand of cooling products from Logisys/Deepcool, aimed at gamers. This huge cooler has two twin tower heatsinks, eight heatpipes, one 120 mm fan and one 140 mm fan. We already reviewed the Dracula VGA cooler from this brand.

The Assassin box is enormous. It comes in black, as seen in Figure 1.

Figure 2 shows the contents of the box: heatsink, fans, a syringe of thermal compound, a manual, a case sticker, and installation hardware. Although the Assassin comes with two fans and supports up to three, it comes with four pairs of wire fan holders.

The very large base of the Assassin is perfectly mirrored, as seen in Figure 8. It is made of nickel-plated copper and soldered to the heatpipes.

Figure 9 shows the fans that come with the Assassin. At the left is the 140 mm fan with PWM control. The 120 mm fan is shown at the right and has a three-pin connector, which means it is not PWM-compatible. Both fans have a rubber-covered frame that reduces vibration.

The installation of the Gamer Storm Assassin is easy. Just insert the screws in the appropriate holes of the backplate, as shown in Figure 11. There are rubber pieces that hold the screws in place.

Insert the backplate on the solder side of the motherboard, and then install four spacers and two metal holders on the component side, as shown in Figure 12.

Next, put the cooler in place and secure it by screwing a metal bar on the holders. Afterwards, install the fan between the heatsinks.

How We Tested

We tested the cooler with a Core i5-2500K CPU (quad-core, 3.3 GHz), which is a socket LGA1155 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 4.0 GHz (100 MHz base clock and x40 multiplier), with 1.3 V core voltage (Vcore). This CPU was able to reach 4.8 GHz with its default core voltage, but at this setting, the processor enters thermal throttling when using mainstream coolers, reducing the clock and thus the thermal dissipation. This could interfere with the temperature readings, so we chose to maintain a moderate overclocking.

We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)

We compared the tested cooler to other coolers we already tested. Note that the results cannot be compared to measures taken on a different hardware configuration, so we retested some “old” coolers with this new methodology. This means you can find different values in older reviews than the values you will read on the next page. Every cooler was tested with the thermal compound that comes with it.

Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings.

During the tests, the panels of the computer case were closed. The front and rear case fans were spinning at minimum speed in order to simulate the “normal” cooler use on a well-ventilated case. We assume that is the common setup used by a cooling enthusiast or overclocker.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top opening of the case. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

Error Margin

We adopted a 2°C error margin, meaning temperature differences below 2°C are considered irrelevant.

Our Tests

The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the full speed.

In the graph below, you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

Main Specifications

The main specifications for the Gamer Storm Assassin CPU cooler include:

* Researched at on the day we published this review.


By looking at the size, the quality of construction, and the number of heatpipes of the Gamer Storm Assassin, you can see that it is a high-performance cooler. This time, appearances were not deceiving; the Assassin reached about the same level of cooling performance that we saw on the best air coolers we tested to date. It is also relatively quiet for a high-end CPU cooler.

The Assassin is very versatile as well. You can use it with only one fan if you want it to be even quieter, or you can install a third fan (or even change the stock fans with stronger ones) if you need more cooling performance.

Due to its high performance with low noise, versatility, and stunning overall quality, the Gamer Storm Assassin from Logisys/Deepcool receives the Hardware Secrets Golden Award.
