Cooler Master Hyper 612 PWM and GeminII S524 Review


Testing and Setup:

Testing of these heatsinks will involve applying a load simulated by Prime95, using small FFTs in stock and overclocked scenarios, where both idle and load temperatures will be recorded. Load temperatures will be the maximum value displayed in RealTemp after running eight threads in Prime95 for one hour, and idle temperatures will be the minimum recorded value by RealTemp with no computer usage during a period of one hour. The temperature values for each of the four cores will be averaged and displayed in the graphs below. The ambient temperature is held at a constant 23 °C throughout testing of the Cooler Master Hyper 612 PWM, GeminII, as well as the comparison units. All the data shown in the graphs below is in degrees Celsius. The included thermal paste from Cooler Master will be used during testing and thermal pastes on other heatsinks from their respective manufacturers will be used. The fans on each cooler will be run at full speed for these tests.

Testing Setup:


Comparison Heatsinks:





Well, the large size of the Hyper 612 PWM certainly pays off, even using only one fan! I'm sure that adding an additional fan to the mix for a push-pull configuration could have lowered the temperatures even further. For the GeminII S524, the temperatures aren't incredibly outstanding but we see that for a low profile, high clearance cooler that generally low temperatures are achievable. The end-result of the overclocked load test wasn't something to greatly admire, but shows that this heatsink wouldn't be the best choice for someone who had the room for a large cooler and plans to overclock.
