Prolimatech Armageddon 6-Heatpipe CPU Cooler ReviewFri, May 21, 2010 - 12:00 AM
To kick things off I compared the Prolimatech Armageddon to the random samples collecting dust on my shelf. For comparison I have the Spire Thermax Pro and the Thermaltake Contact29. For the testing I first measured the idle load by letting the system sit idle at the Windows desktop for 15 minutes. Then I loaded OCCT and set it on a small data set for 30 minutes and measured the peak temperature achieved during the test. For temperature measuring I used Core Temp and averaged the temperature across all six cores. My Core i7 980x seems to report cooler temps than possible as ambient was between 19 Celsius and 20 Celsius, so figure a few degrees warmer than the reported temperatures for accurate temperatures.
It is no surprise that the Prolimatech Armageddon walked all over the other two heatsinks. The interesting thing to note is that the Armageddon also was far quieter than the Contact29 at full load and slightly quieter than the Thermax Pro even with two fans spinning away. Since the above results were so underwhelming I decided to push the heatsink a bit further. Below is the Prolimatech Armageddon run at 3.33GHz and 1.05vcpu and then a run at 4.2GHz with 1.275vcpu.
With the ~900MHz jump in CPU frequency and an additional +0.2vdc the heat dump from the processor jumped dramatically. The idle temperatures were averaged to 22.8C due to me swapping boards and the Rampage III Extreme running the fan at a higher speed at idle. Load temps though jumped to 70.8 Celsius, a little over 20 Celsius jump compared to the 3.33GHz run. For the testing though we weren’t thermally limited but voltage limited so those of you willing to push more voltage through your CPU could easily see upwards of 4.3GHz to 4.5GHz stable through OCCT while keeping temperatures under 80 Celsius.
