105C to 110C _internal_core_temp_ is the AMD spec'd failure
temp. Read that as 'fried forever'. Bios temps aren't very
useful. The system has just booted an is under low load. As Ron
mentioned earlier, and AMD docs support (overclockers have long
known), the actual core temp is 10C to 20C hotter than the temp
you see in bios or from lm_sensors. It is afterall, an external
contact temp from a probe. 45 to 55C for current XP's is normal.
Just keep in mind the actual internal core temp is closer to 60
to 75C. If you see less than 40C from a probe, the report is
bogus unless you're usin a water cooler.
Case coolin IME is more important than fancy dan cpu coolers.
Also run fans at 100%, forget the variable speed gimmicks. Use of
thermal grease rather than pads is mandatory. I've seen Volcano's
mentioned in this thread. I favor them (Volcano 11+, 4800rpm big
fan) .... because they're easy to keep clean. Avoid coolers that
have many close together vanes. They're impossible to keep clean,
tho they work just as well when new.
Hoyt, 122F = 50C, so your processor should not be unstable at
temps of 105F. If the readings are accurate, it probly means
you've enabled slowin the fans down when the cpu isn't under
load. The fallacy there is that cpu core temp and load can spike
up instantly .... heatsinks by the nature of their mass, take a
long time to cool to respond. On most laptops this is a
necessary evil. Don't do it with a desktop, certainly not with a
server.
One more thing. cpu's that have been run hot ... don't heal.
