Big drop in idle temps...

I returned my Asus P8P67pro B2. I bought an MSI P67A-GD65 B3 instead. Built it tonight and it's working fine straight out the box (are you listening,Asus? [dig, dig;)]).

Anyway, my idle temps with the Asus board hovered around the 36C mark. Not unreasonable I believe. I did spread the paste with a credit card on the cpu when I installed the 2500k in the Asus. This time, with the MSI board, I used the pea method and let the heatsink do its own spreading on contact. My idle temps as I type are 31C. A whopping 5C difference. Clearly the method of application for the thermal paste has made a difference. I was also wondering if the manufacturer of the motherboard has anything to do with this drop in temps. Vcore?

What else might contribute to this perceived drop in temps? I say "perceived" because I can't know for sure now if either board shows accurate temps.

Mind you, this motherboard has only been running for a couple of hours so far. I hope I'm not tempting fate :).


Edit: 10 minutes of prime gave me 42C, 46C, 48C, 50C. Nice.

Oh, all at stock speeds, by the way.

Hi, well the only known varible you've quoted is the way you've used the paste. Other than that it could be the way each motherboard measures the temps. Did you use the same temp software and is it calibrated in the same way?

Arctic Silver5 both times (same tube was used). Coretemp each time. Calibrated? No. Just relying on what core temp says. Good question though. Without calibration then all temps are ball park I suppose.
