Testing of the heatsink will involve load simulated by Prime95 using small FFTs, in stock and overclocked scenarios. Idle and load temperatures will be recorded. Load temperatures will be the maximum value displayed in RealTemp after running 8 threads in Prime95 for an hour, and idle temperatures will be the minimum value recorded by RealTemp with no computer usage after one hour. The temperature values for each of the four cores will be averaged to get one value for the comparison values. The ambient temperature is held at a constant 25°C throughout testing of the Hyper N620, as well as the comparison heatsinks. All the data shown in the graphs is in Celsius. The thermal paste Cooler Master included was very dry and I had difficulty spreading it over the heatsink's base, so I used Arctic Silver Ceramique as an alternative for all comparison heatsinks.

The temperatures were right about where I expected them. These i7 chips do run quite hot, and I was thinking that overclocked load would be low 70s after evaluating the cooler in-depth. The temperatures stayed at a comfortable level when overclocked, nearly 20°C cooler than the stock Intel heatsink.
