Test System Setup and Thermal Results
I would first like to thank HIS, GIGABYTE and InWin for supplying products for me to test with.
Testing for the CPU coolers is done with the use of RealTemp to ascertain temperatures, Intel Burn Test to deliver the load to the CPU and CPU-Z to verify the CPU speed and the voltage being used in Windows.
For the "stock" runs, it's more of a plug and play setup where the PWM of the motherboard is in control of the fans speeds for both the idle and load results. For the overclocked runs, I load the CPU at 4.5GHz and idle results are obtained with 7.5V to the fans while the load run is set to deliver 12V to the fans.
For the sound testing results, I obtain those while I am controlling the voltage at 7.5V and 12V as well. Sorry for the change in the charts again, but I got the full effect of AVX support and 104 G-flops now, so the older results don't directly apply to the results I get now.
The Dark Rock Pro 2 delivered really good results with both the stock clocks and the overclock applied to the processor. The added voltage made little difference to this cooler as the results show both of them were at 26 degrees while testing.
Look at that, it's a dead heat tie between this cooler and the Thermalright dual-tower concept. There are a couple of differences yet to cover, though. The Dark Rock Pro 2 is quieter, looks better on more builds in my opinion, but cost a bit more as well. Take a look at the audio results and I will work out the rest in the final thoughts.
