Good to know that someone else has the same spikes
Haha, yeah, I did the same thing as you did, basically sitting a fan on my video card. Eventually I'll figure out a better method.
Should I worry about not knowing the temp of my southbridge? I'm definitely overclocking the "FSB" at 1GHz right now, but the southbridge is watercooled.
One thing that I'm concerned about is the CPU temp that Motherboard Monitor displays. In the BIOS, the CPU temp is around normal, about 40C. Right after booting into XP, however, MBM shows the CPU temp as 70C+! I've tried other temp monitors like speedfan and MBProbe, but all do the same thing, so I've been putting an artificial correction of about -31C to the 70C+ reading, making the final reading around 40C. I've got the latest BIOS, and this is the second AN51R board that I've gotten with the same problem. Should I be worried about this incorrect temp reading?
