What else is different about the two machines?  What about case fans?  Are
the PS fans blowing the same direction (PS fans really shouldn't suck in
without ducting the hot air right back out, I've found).  When I was trying
to fix overheating on my Athlon, I opened the CPU case and found that the
grease blob on one of the cache chips was way off-center, so I replaced all
the blobs with a nonconducting silver-based grease.  It would be real useful
to have a way to independently sense air temps inside the case - I use a
Fluke DMM with a thermocouple adapter and a bead probe that I can put
wherever I please.  I was checking intake air temp, output air temp,
heatsink surface temp, etc. with it.  http:/www.overclockers.com is a REAL
good place to look for cooling info and links.
