To test the coolers we used an Asus P8Z68-V motherboard and an Intel i7 2600K which we overclocked to 4.6GHz for overclocked part of the testing.

To stress the CPU we ran the Small FFT's test of Prime95 for 20 minutes using the RealTemp utility to measure the core temperature's, averaging out the temperature for all the cores.
