I have a
K7S5A rev. SO board by ECS. No hiss and boo's. Its cheap and so am I.
I just put a Radiator that has a fan running on it, wired to my CPU fan pinout. The hmonitor display shows that my temperature is all over the place.. 80 F - 200 F. The socket has a green plastic bulb thing just under the cpu. (I think this is the temp guage) The mobo is new. The temp is wrong.. I would have killed my comp if the temps were that.
I also have a thermal probe with my block. The probe is inserted in a hole about 1 mm over and ovset from the core. It shows my temperature WAY more accurately. If I pull it, it shows great room temperature and goes up instantly when a load in placed in the cpu when back in system. I believe its right. It shows the comp at good temps.
QUESTION: Why would my onboard temp sensor be so far off? Does the calculation for the cpu temperature have something to do with what fan is in the cpu fan plug?
Should I just ignore the onboard cpu meter? I would like to have wired my case using internal measurements to shut down my comp, but cant do that if its on the fritz. Should I take back the board, and replace it with another, or does the fan plugged in play a factor?
Constructive suggestions appreciated.
