Test System and Thermal Results
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 24.5-25C 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 1600MHz and loads at 3500MHz for the stock settings. I also set the memory to run at 1600MHz for stock. As 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. This allows me to gauge the lowest and highest fan ratings for my charts.
As you can see I tested both the Quiet mode, designated as QM in the chart and the Performance mode designated as PM. For a cooler of this size, there is nothing really shocking or depressing about the idle results, it is on par with the average to better than average results across both modes.
When we load the processor at both stock and overclocked settings, the HE01 does falter a bit in quiet mode with the OC applied, but that is fine. With the flip of a switch and definitely more noise, I was able to take that 76 degree reading and drop it to 71 degrees. Even at the stock clocks, I was able to get that same five degree improvement.
Keep in mind, if you have a couple of high performance fans, or order a couple of these 140mm fans that comes with the HE01, you can have 513 total CFM blasting through this cooler and I guarantee you would drop the temperatures considerably more for sure.
