Run 1 was Arctic Silver 5 which had cured for approx 52 hours. I ran mprime as noted above for 4 hours.
Run 2 was with MX-4. I ran mprime as noted above for approx 1-1/2 hours.
Histograms in blue show the temperature distributions for AS5 and those in pink show the same for MX-4. The solid black line for each core is the average temp for each core. You can clearly see differences between the two of 2-4 degrees (allow for +/-1 C due to the ambient temp range). AS5 was the superior TIM in the test experiment.
Test system
Processor: i7-4790K @ 4.40 GHz (vcore 1.232 volts under load)
HSF: NH-14D with 120mm and 80mm fan running at max
Motherboard: MSI Z97 MPOWER MAX AC
EDIT: I have to totally invalidate my findings based on a configuration oversight: it seems that $HOME/prime.txt on linux dictates what size FFT mprime uses. I have found that using "large FFTs" as I did the the experiment allows for values of 128k-1024k which is a range that causes a given CPU various levels of stress. The trend is for smaller values to give more stress and as a result, higher heat. In short, I have no way to go back and see which FFT size prime was using when I compared these two. Here are my findings using the same TIM, but varying the FFT size. Each run is a average of 20 min of running.
I have since locked the FFT size to 400k and will repeat this experiment.
