The Test System and Thermal Results
I would first like to thank HIS, GIGABYTE , InWin and AVADirect 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. All of the testing is done with an ambient temperature of 24.5-25°C and humidity is maintained to 35% sometimes less.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. Speed Step is active and the processor idles at 1600 MHz and loads at 3500 MHz for the stock settings. I also set the memory to run at 1600 MHz for stock. As for the overclocked runs, I load the CPU at 4.5 GHz and idle results are obtained with 7.5V to the fans while the load run is set to deliver 12V to the fans. This allows me to gauge the lowest and highest fan ratings for my charts.
At idle, whether stock or overclocked, this custom kit with the EK-Supremacy sits right near ambient temperatures as one would expect from a CPU only on such a robust system.
Using IBT sets the EK-Supremacy and the accompanying kit ahead of all of the competition. At stock it is a degree cooler than the closest competition of another loop and overclocked it took the lead by two degrees.
