cool 'n' quiet - negative temp readings

my motherboard reports negative cpu temps (obviously faulty). could this interfere with cool 'n' quiet's ability to throttle the cpu? i would like to know if i have any protection from overheating.
 
I would say that you need to post more info - system specs, reported temps, etc..

What cooling method are you using ? If your using phase change cooling, then negative temps are normal.

I agree with wusy that it most probably will interfere with CnQ functionality.

What motherboard do you have ? Some boards have functions in BIOS where you can configure shutdown temps - however, this may not be useful in your situation if the temp readings are incorrect. I'm not sure that the AMD cpu's themselves have shutdown protection (I heard that Intel cpu's do, but I am happy to be corrected on this - not really sure).

As also previously stated, it's very unlikely that overheating will be a problem, especially with the more recent AMD cpu's with stock hsf. Only in extreme conditions (very high ambient temps, poor air circulation in case, cpu fan failure or badly seated heatsink for example).
 
ok check my sig (that moo thing was getting old)

yes the bios says cpu -10 (system +33). so does speedfan. right now the bios keeps all fans at 100%. not very quiet - another reason to fix these negative readings.

What cooling method are you using ? If your using phase change cooling, then negative temps are normal.

the zalman cnps9500 uses heatpipes. there is a passive zalman (nb47j) on the nVidia n-force4 ultra chipset but man does it get hot. i got a digital heat probe today. being reeeaal careful ill try to get readings.

exactly, the shutdown options available in the bios dont cover negative numbers.

Well, you have a nice hsf on there, and as previously stated, there are no real worries about overheating that cpu.

However, it clearly looks like a faulty sensor on the mobo. You tend to get negative readings when the sensor isn't connected.

The only suggestions I have are to either live with it or replace the motherboard (good option if it's still under warranty).
 
nah i flashed the bios already. last effort, ill try motherboard monitor as i hear it can read temps differently.....

BTW! - C&Q runs fine. it throttles the cpu to save power, not to reduce heat so it doesnt use temperature/rpm's (im assuming from reading at amd's site). i was a little confused - its my first AMD.

still the original concern remains; whatever protects the cpu from overheating i hope isnt using those faulty temps. still looking into it.
