Read CPU temp

VeganFanatic

I was looking for a code snippet to read the temperature of a CPU. I have a project that trashes the machine and watching the CPU temp seems prudent. I speculate there is a Winbond chip integrated into the motherboard. So the is obviously direct calls to the chip. Perhaps there is an API I can call? Direct reading of the hardware is less desirable than an API as the chip may not be the same in all machines.

I personally doubt there is a common API to perform what you want, if i were you i'd try to search for OpenSource motherboard/system monitoring software (e.g. on SourceForge[^]) and study it to learn how they are doing it, it's probably not simple if you want to provide support for multiple systems. If you DO find such an API do tell us, please, good luck.

I looked through the WMI classes and didn't find anything relevant. :)

If needed I guess another template/class can act as an API. When in doubt, drop down to assembler. Then the whole machine is accessible.

Assembler or not, different manufacturers give different ways to access such information, if any, even different versions of the same motherboard might give you different ways, sadly. I wonder if there is some kind of a standard for such an information that is just not ingegrated into Windows / no manufacturer really follows, or no such thing exists at all. I mean, graphic card manufacturers provide DirectX compatible drivers for their cards (they ought to, noone would buy their card if they wouldn't...), why not providing drivers for motherboards with such a compatibility...*sigh*, well, one can dream, can one not?

Looks like a glaring omission, as I have searched MSDN and found nothing, Google, no good and on Soureforge the stuff is specific to certain boards only. I guess I will have to ask users to watch the temps manually when using my benchmarks.

When i was googling for this temperature monitoring API thing i saw a link about using Motherboard Monitor to gain temperature information (Motherboard Monitor is a freeware app. that can give you temp and voltage informations afaik), maybe try googling for it, it could be an option, i think the google hit mentioned something about using shared memory to communicate with MBM, if you think, check it.

You may want to have a look at this : http://en.wikipedia.org/wiki/System_Management_BIOS[^] It is the wikipedia page for the SMBIOS or System Management BIOS standard. Hopefully that has something of value. If nothing else, you have another term to search for. ;)
