Old question, I know. How accurate are the mobo thermal sensors?

[Crazy Jayhawk]

I have an Abit ST6-Raid. I'm not sure how accurate the thermal sensor for the CPU is though. The numbers it gives me are 23C idle and up to 45C under load.

The idle number is pretty good, but I'm not sure if I'm getting the whole picture. Any suggestions other than getting a Digital Doc or something similar? :eh?:

their is no way to tell the real temp using built in hardware monitors, get an external one or software one like motheboard monitor

How accurate are the 8KHA+'S???

Even if you use a diff program it makes no difference it still reads off of the same sensor!!!!

Well, my suggestion is getting some kind of decent thermistor that would fit between your hsf and cpu (you *definatley* don't want that to be too fat).

Here (http://www.overclockers.com/tips507/) is a good article on why they aren't very accurate. :)

Buy a CompuNurse , DigiDoc or any other small themal sensor.

My EPOX 8k7a reads temps 10C to low at idle and at load but when I used CPUcool to basically turn off the processor (experimenting) the onboard sensors read temps higher then they really were. I know when the processor turns off it will go to slightly above room temp , which is the temp CompuNurse shows but the MBM sensors showed the cpu about 7C above room temp which of course waqs wrong.

Not very accurate. I normally add 10c to be on the safe side for approx measurements.

Wouldn't having a sensor in between the cpu and the HSF reduce heat transfer?

[The Overclocker]

the good thing is, your temp can never be too low

NO but if the sensor is in between the core and the hs you will have bad heat transfer you may even fry a cpu like that.
