? About temp sensors...

[deepinya]

Ive been reading about all sorts of programs to measure CPU temps but which is the most accurate?

I just got a XaserIII and it comes with a thermal probe that sticks to the bottom side of the CPU. Then it displays the readout on the LCD screen. Is this the most accurate way of measuring CPU temps? Or is it more accurate to go with a program? ie...speed fan, asus probe...

Thx

Wow, none of you brainiacs know the answer? :frown:

I'd wager that it'd be more accurate, but not quite as convenient as using a program which allows logging, voltage monitoring, rpm monitoring, alarms, etc. It would be a good idea to use it to calibrate your motherboard's indicated temps, as they can sometimes be off.

In most cases an external temp sensor is the most accurate way to measure your processor temp. You'll never be 100% accurate though. Most of the on-board (built into the motherboard) and even on-die temp (built into the processor) senors are "dumbed" down a little by the motherboard manufacturer by as much as 10 degrees. An example would be my Epox 8RDA+ motherboard. The temp sensors on the board read about 5-7 degrees higher than the ones from my external probe (Vantec Nexus Multifuncion Panel). I saw a thread (http://www.aoaforums.com/forum/showthread.php?s=&threadid=14862) where an Epox technician explained that this was to reduce support calls due to the "overtemperature protection system" on this board. They give themselves a little headroom (i.e. intentionally have the senors report higher) so that someone doesn't set the OPS (see above) to go off at 110 degrees or something like that. Anyways, most processors are built to operate up to 160 degrees f so you shouldn't worry about temp differences too much as long as their under 130-40 you're ok. My 2 cents
