[plug] CPU temps [OT]

[John Usher (Maptek)]

We've tested a fanless Celeron II 400 system at various temperatures (ie
cooked it) and it actually ran OK up to at least 80 degrees C. After
that though, it just got hotter and hotter. We got it past 100 degrees
before we shut it down. Once you reach the critical temperature, the IC
just becomes a heater and sucks as much power as it can to produce as
much heat as it can. There was a 20 degree temperature rise in almost no
time at all.

It was rated for 70 degrees, just like most ICs seem to be.

After that test and the resulting bending of silicon, the processor had
a lot less heat tolerance, and 60 degrees would kill it.

But it did still work! Amazing.

I have heard that cooling is the one area where AMD falls down compared 
to Intel.  I've never had a problem myself but then again it hardly ever

gets above 40-45deg outside in Fremantle; I've just heard people say 
that they've had AMD boxen crash in any sort of heat.
