I'm using AMD X2 (939) 4400+ with Sapphire PC-A9RD580 motherboard + a Sapphire X1900XT.
My motherboard sensors reports (read from BIOS),
CPU VRM Temperature - 45 C
AMD K8 Temperature - 33 C
Ambient temperature - 46 C
So my questions are..
1. Why is the VRM temperature so high ? Is it OK for this CPU ?
2. The K8 temperature is the actual CPU temp, am I right ?
3. What do you think about the ambient temp ? (its pretty hot here)
Well your CPU temps seen more than ok my INTEL is normally idle at 58 so you wont be melting down any time soon. The only thing that seems high is your Ambience. My ambience actually hit 70 last month but yours is still high. A bit of heatsink paste on the northbridge heatsink helped drop it down to 31 c so i would check if your northbridge is ok. It may have a rubbish heatsink. If this temp droms you may also notice a significant drop of about 3c in everything else.
VRMs run hot but can take a lot of heat since those are very simple components, depending on the design of your motherboard, you can stick ramsinks on them to cool them down if you intend to overclock.
