i've encountered quite a situation with my new workstation. i'm running an
asus sk8n mobo with an opteron 144 processor. when i enable the "q-fan"
option in the bios (which regulates fan speed according to heat output), upon
restart, it STOPS

....sorry, i pressed the wrong key. anyways, i contacted the company
from which i purchased the computer, and all tech support could offer
was to turn the option off. of course, now the fan always runs at top
speed, and is quite loud; to say the least.
the latest bios update that asus offers does not include any fixes relating
to my situation, so i was hoping to reach out to anyone who may have
some ideas.
i run amd athlon 1.8 at home, and i know that i would have serious a
meltdown if my cpu fan wasn't running; so this is quite strange. perhaps
that becasue the mobo if fairly new, they haven't worked out all the bugs?
thanks in advance. any suggestions are welcome. sorry for the lenghty
novel.

What you are trying to do is use the cool and quiet feature which I don't think it is supported for Opteron's yet.

Furthermore, this is also a function of the BIOS so you may need to combine this function with an Athlon 64 FX, not the Opteron and then make sure you have the latest BIOS for your board and then it should work.

I run a FX-51 on the SK8N, and YES my CPU fan can and does stop.
(Running Q-Fan in the BIOS)

It is because Q-Fan has four levels:

Fan OFF
Low
Med
High

I find once my CPU heats up to the low setting the fan does kick in and everything is safe.

But if you are running cool-n-quiet also, you CPU will go down to 800mhz, and run VERY cold, cold enough no fan may be needed, but don't worry the fan should turn on if the CPU heats up.

Runs some tests first!

BTW...I wish Cool-n-quiet worked on FX's
