So, with intensive POV-Ray work, I always like to open up speedfan and 

(FREAKING HOT o_O! Normally they run about 50-60) I see no evidence of 
CPU throttling down, though. But the even weirder thing I noticed was 
the voltages. 1.2, 5, etc all seem to be fine and stable -12 comes in 
around -15 and -16, and +12 seems to be all over the place, but never 
anywhere near 12! When under high CPU load, it hovers around 5-6 volts, 
and when the CPU is idle around 1-2v. (!)

The system is stable, seems to do the torture test fine, GPU operates 
normally, and everything appears to be humming along normally.

I may need to pop the heat sink off the cpu, clean it off, and re-apply 
some heatsink goop to get the temps down... All fans are nominal, there 
was some dust collected on the filters on the case, but that has been 
cleared off, airflow is great, it doesn't blow hot. Ambient temperature 
does have a lot to do with it. After the AC kicked on (we've been warm 
lately) CPU temps were arouns 85 under full load.)

The voltage is weird and disconcerting, though. I may wind up buying a 
new PSU as an insurance policy. I don't want a temperamental power 
supply trashing my CPU and motherboard.

Maybe the readings are just totally wrong?
