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 24.5-25°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.
You will also see that the charts have been slightly adjusted. From now on I will mention the idle temperatures if there is something worth noting other than an average of twenty-five to twenty-seven degrees as the PWM controls and SpeedStep allow for almost ambient results in most instances. What you are now getting is a stock speed loaded temperature chart and an overclocked loaded temperature chart. To clean up the audio results, I also removed all of the fans that aren't on the thermal charts. If you want to compare those results to new coolers, the old chart is still available in the older reviews.
I know we are dealing with a thinner than average fan, and I was in the configuration that had the fan blowing up off the motherboard. At the stock level of the 2600K which delivers 95W of heat to the cooler, and from the chart I am pretty much right on specs for this test. That in mind, I do think that a 50 degree result with a cooler intended to only cool exactly this TDP is respectable, and good for a cooler with its short stature. I mean, it beats out quite a few larger coolers on the list, which has to say something for it.
While the results here may not look all that good, you have to keep it in perspective. This test applies 125 to 150W of power to the coolers, and for a cooler rated to only work up to 95W with this fan on it, I have to say the simple fact that the test didn't make the CPU throttle is a good sign of its efficiency. If room is not an issue, I could see a pair of 25mm thick 140mm fan with about 3.0mmH20 static pressure and some good CFM could take this cooler right on into the TPC-812 range, which is really good for a cooler of this dimension and C-Style design.
