to both of you, i'd suggest reseating your processors and using arctic silver 5 thermal compound... 45C is just too high an idle temp for a C2D. I have a scythe ninja cooler, and my e6700 idles at 22-25C... so for a normal cpu cooler, i'd say you should be idling b/w 30-35C.
I am using artic silver 5...I believe I may have used a little too much of it though. Also, I've heard talk of the intel d975xbx having temperature readings off by 10-15 deg C.
use CORE TEMP to get ur temps, 40c is bout normal for a core2 on stock intel hsf in a 20c room
There should be a general rule of thumb here?
19-30c idle would prolly be the most ideal temp.
38-45C idle temp is okay or decent.
55-60C idle temp... NOT okay.
Unless all circumstances are the same (same MB, room temp, perhaps HSF), people shouldn't trust someone elses temp.
Worried about the same thing with my Core 2 X6800. Always around 41c - 43c. Found the Intel info. It's operating perfectly. Here's the link:
