Testing and Setup:
The testing of the heatsink will consist of a load simulated by Prime95, using small FFTs in stock and overclocked scenarios. 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 after one hour. The temperature values for each of the four cores will be averaged and displayed on the graphs below. The ambient temperature is held at a constant 25 °C throughout testing of the HR-02, as well as the comparison heatsinks. All the data shown in the graphs is in degrees Celsius. The included thermal paste from Thermalright will be used during testing, and thermal pastes as packaged from the other coolers were used with each heatsink respectively. Even though this heatsink is supposed to be passive, I will also be testing it using a CoolerMaster fan regulated to 1300 RPM to test the low noise performance of the HR-02. This same fan will be used on the only other heatsink in the comparison listing that does come without a fan, the Super Mega. Two fans are used with the Super Mega in a push/pull configuration at the fans rated maximum speed of 2200 RPM each pushing / pulling 94CFM. All other comparison heatsinks are tested with the fan system that was factory installed.

Operating passively, the Thermalright HR-02 performs exceptionally well. Run passively the HR-02 delivered a better cooling performance than two of the four heat sink it is compared against. When paired with a low speed (1300 RPM x 1) fan the HR-02 hangs within 6 degrees of the top of the line offering from Prolimatech (2200 RPM x 2) in the load testing while using only the one fan, actually beating it in the idle scenarios with much less noise. This is most likely due to the larger amount of surface area on the fins, which allows heat to be dissipated more quickly. On the next page, I will wrap up this review in my conclusion.
