Getting CPU and Fan stats without MBM or Everest

PureSpider · Post by **PureSpider** » Sat Aug 09, 2008 8:35 am

Hi guys!
I've been searching for the whole day for any clues on how to do this now, but wasn't able to find anything.
So I'm asking here...
How can I get the CPU Temp and Fan RPM stats without using Motherboard Monitor or something similar?
How do they do it?
I've tried with the GiveIO.sys but I only get rubbish for the adresses/don't know which addresses I should read from...
Any help would be greatly apreciated!

€dit: TO get this clear... I can access any address using GiveIO.sys, I just can't figure out the right ones.

install linux and type sensors;)

Huh? And then?
Does this work with cygwin, too?

SpeedFan ?

... without MBM or Everest or Speedfan or any similar...
I need my own code for doing this as I don't want to display the results but do something different with it!

that information is gotten from the mb, so your going to need a way to talk/listen to it. c++ does not inherently have this ability, so it depends on whether or not you want to do this for windows, linux, or os x.

for m$, somewher ein that big heep of api & visual studio there is probably an api to do it that may or may not be useful.

for linux, there are probably several diffrent packages that provide acess to get that information

for mac, well good luck i have no clue

but all in all, your"own code" for this will be different for each platform you are writing it for.

Pure you're going to have to use SMBUS information to get those, and the addresses and information vary by implementation.

There is an API for it, called WMI; Which needs to be supported by the mainboard drivers... and in 90% it isn't... that's the case for me, too =/

That's right, I just dont know how to get or use them...
€dit: My SMBus is at address 0290 (hex)... now, how to use this?

Restart your computer and go into BIOS. CPU and fan stats are usually somewhere in there.

I imagine that's not the solution you want, though.

I cant use the stats in my BIOS within my own code, and thats what I want to

But thx for the reply

Couldn't tell you how to get the information you want - perhaps a perusal of the manufacturer of the SMBUS chip's website would help? (It's possible they don't even tell you and instead want you to call their own DLL to get the information)

Do you have to be doing this under windows ?
There's libsensors for linux (from which the 'sensors' program reads it's data).

sample output:

Yes unfortunately I need to do this under windows =/

Man, that's a lot of ISA adapters you got there dougal, you must be rockin that new VGA card with 512(!) kb of ram (1024x768?! amazing!)

lol yeah, most sensors still work over an ISA bus. crazy.
