I built a ystem using the Intel E8400 (3 GHz Core 2 Duo) and DG35EC Desktop MB. The E8400 comes with a heatsink with pre-applied thermal paste, which I installed correctly (as far as I can tell). When I started up the computer the first time, I was sifting through the BIOS settings and happened across a Hardware Monitor that said my CPU was running at 102 C and the ambient was 42 C. I immediately exited and shut down. I started everything up again hours later and went straight to that screen in the BIOS config - same readings. No changes while I watched (no increasing temps, for example). This seems suspicious to me for a few reasons, but I wonder if anyone can help me out.
First, the CPU temp is obviously very high and I would expect damage from the first time I booted (several minutes @ 100+C) - but everything seems okay. Second, even for a poorly-seated heatsink, that temp seems ridiculously high. Third, the ambient was way above actual - the room is ~15-17 C and I actually had the side cover off during that period. I do not notice any warmth on the heatsink or in the air around the MB. Finally, even if the heatsink were completely off, would the chip heat up so much just from loading the BIOS? I've read that the E8400 has had some temperature reading problems in the past - is that still true today?
Thanks for any advice/thoughts you can give.
