hi everybody, i have a minor inconvenience with one of my WIP computers, and was wondering if anyone could help.
the problem is that in the bios, it seems that the temperature sensor for the cpu is about 10 degrees above what it actually is, i have quite the reason to believe it is, i mean.
so for this computer, i have been trying different types of fans for this passive cooling heatsink, trying to find the best one for a small form factor build. i tried several, not noticing much of a difference between them all, so i went with the first one i tried that was a fan from a lga 775 heatsink, since it had the best cfm rate.
when i first had this fan hooked up, the cpu would idle in the bios at 50 degrees celsius, now it says its idling at 60. nothing has changed from the first test, not even the physical temperature of the heatsink. why is it telling me this?
the board is a asrock P4i65G mini atx board. it has a 3.2ghz intel pentium 4 installed with a passive cooling heatsink from an old dell dimension 2400.
It has 512mb of ram, a 256mb pci video card, and a 350w psu.
I know for a fact that the physical temperature hasn’t changed because when it had been at 60 before any fans were added it was hot enough to burn my hand a little.
and also, booting from cold, it has never exceeded 45 degrees by the time i got to the hardware monitor screen, it said 57 degrees when i start it cold now.
so what exactly might be wrong with it? should i trust what the bios is telling me? or should i get a digital thermometer for monitoring the temperature?
UPDATE: when i started it up again it started saying it was 89 degrees, something is definitely up here…
