I bought a replacement supermicro motherboard off fleabay that has
dual Opteron 250 @2.4GHz. The cpus have passive heatsinks, it is in
a supermicro 2U chassis with 4 front fans.
do you have the air shroud? this plastic thing that forms a "tunnel"
over the heatsinks? it is required.
No, the motherboard didn't come with that. If I can find one will
that mean I don't need the active heatsinks?
Thanks!
As a followup, here's what I have done to try to alleviate this:
I bought and installed the plastic air shroud using the passive
heatsinks that came with the motherboard. System still overheats and
shuts down within a couple of minutes.
I bought 2 AMD brand active heatsinks, specific to this processor, and
installed them. That meant I had to ditch the plastic air shroud, but
the motherboard manual says that active heatsinks are suggested for 2U
chassis and the air shroud was only $10. I also used new heat sink
compound when I put everything together.
System seems to run okay at idle. but make it work a little--like
compiling a kernel or tar-ing up a big file and the temp indicator comes
on and sysctl reports
temps (on both the kate and lm sensors) finally exceeding 100 degrees C
on one processor, with the other is not that far behind at over 80 deg C.
At that point the system shuts down.
I'm at a loss as what to try next. If I've read the AMD specs correctly
these processors should not exceed 71 deg C but I see temps near that at
inear dle.
Did I just get a lemon motherboard/CPU combo? I still have a couple of
days on my 30 day exchange if this is the case.
Thanks to all,
Jeff
