The 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 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 Speed Step 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.
The stock testing results for this thermal chart is a bit surprising to me, but I ran this test five times with various mounts, but I kept getting back to the 45 degree mark on all of them. That puts it slightly beyond AIO, and right into the mix with some of the custom water cooling solutions.
Thermally speaking, once the overclock was applied, the TD02 does lose a bit of ground. It falls behind custom water cooling as we would all expect, but it is slightly bested by both the H220 from Swiftech or the NZXT Kraken X60 AIO sitting up there in sixth place. Don't let me drag you down in any way though, this 67 degree result still gets the TD02 into the top ten, and that is not an easy thing to do with my CPU.
