Yes, CPU air flow is forced over the cpu copper heat sinks. And the top of
the case is firmly in place.

I let it sit over night to "cool down".  Upon boot-up the CPU temperatures
started around 104-105 F.  Letting them sit in the BIOS noticing the
temperature go up over 130F.

Booting into 5.2.1 with SMP kernel, I ran my perl fork mysql test scripts
six times then it froze. Back into BIOS I went again after a power cycle and
the temperatures were at 185 and 175.  Not as hot as yesterday, but I only
had it up for 10 minutes total from a cold state.

Anybody have any temperature monitoring apps for amd 5.2.1?

Anybody know what the lock-up temperature is AMD sets into their chips?

Or does anybody know how hot their 1U dual opteron 246 servers run? :)
