OK bit of waffle so bare with me..!
Just been testing that my new build (DFI LP ultra-d, Opteron 146, Zalman CNPS9500 HSF, XFX 7800GTEE, 1x 512mb Corsair XMS3200C2LLv2.2 in Antec Sonata II case/PSU) would power up before i take the plunge and fully install the rest of the bits from my old P4 setup so i had just the mobo, GFX card, 1 stick RAM, CPU and PS/2 KB connected up.
All went seemingly well on first power up (after first removing BIOS battery for 5 mins and resetting CMOS jumper) until i noticed the CPU's fan wasnt spinning!
I was in the PC health staus part of the BIOS and noticed my CPU fan speed was flicking between zero and 9000rpm! As the Zalman CNPS9500 is connected to the fan header via a manual speed controller i tweaked this and it started but was acting a bit odd (turn it down a little bit and it'd stop completely etc etc).
So i changed the
CPUFan Fully on if CPUTemp > 50c to 25c saved and rebooted and it now seems ok, CPU fan speed is reported normally and changes as i change the fan speed via the manual controller. All this time the CPU temp in the BIOS wasnt going above 40c no matter what speed the fan was working at (full or not at all!
).
So now at a fan speed i like ie low rpm & quiet! the CPU temp is at ~33c in BIOS, does this sound like a normal temp for a stock Opteron 146?
Can i turn off these
'turn fan off at x temp' type options for the CPU, NB, PMW completely somewhere?
(I have Cool'n'Quiet disabled).
