Right now the CPU is at 49 and the GPU is at 67.  But.... I don't trust 
the sensors.  The CPU is a dual-core Athlon; one of the cores reports 45 
and the other 51 - but both cores are in the same CPU. 

One of the GPUs is at 67 and the other is at 62.  (the third card 
doesn't report a GPU temp but it's a lot hotter to touch.) That's more 
believable except that the temps are like that at boot - 5 deg. 
difference.  So the sensors are basically giving out bogus info.

All I know is that when the reported GPU temps nick above 69 I get video 
corruption, so a $15 cooler isn't a bad bet - it beats replacing 3 video 
cards.
