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 24.5-25�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.
Considering the size of the AXP-100, and the fact that I have the cooler in the horizontal position when testing it, the results at stock are pretty good. The TY-100 mm fan is the better choice under PWM settings, due to the lower RPM of the TY-140 in these conditions. Coming in just behind the much large NH-L12, and in front of the NH-L9i and PH-TC90LS is right where it should be in my opinion.
I went ahead and applied the overclock just for giggles to see how well I could abuse the AXP-100. Out of the three coolers I compared in the stock run, there is only one of those three that could even handle this without failing the testing due to overheating, but the AXP-100 was able to hang in there, and after some 45 minutes of abuse, I was reading 93 with the TY-100, and 94 with the TY-140.
I will say this though, while the TY-140 seems like a waste of time and energy, since the plate has 120mm fan mounting, you can easily swap out fans for something you have at home to allow whatever headroom you need, it just won't be near as silent as either of these solutions. All the same, I must give respect for the simple fact that this tiny little cooler was able to even finish this test.
