I'm using a Toshiba Satellite M40X and I'm trying to use SpeedFan to control temperatures and stuff. But the thing won't recognize my fans or my cpu -- only the S.M.A.R.T hard drive. I'm supposed to be able to alter fan speeds, etc. but I can't.

On the SpeedFan website it says: "A simple ON/OFF function is available and it needs the device driver from Toshiba in order to work" for the toshiba boards. http://www.almico.com/forumvotes.php?id=126812
it's just not working! help!

If you're interested in checking temperatures, there is usually a function in the BIOS for that. Programs like Speedfan, and Motherboard Monitor tend to be unreliable at least in my experience. Best way to check is in the BIOS, short of using one of those nifty infrared thermometers.

Aha! But it is not possible to alter fan speeds from the bios, or is it?

I have no idea where to find it in the bios

In my experience, many laptops don't have the sensors, or they're not compatible with most of the utilities that read the temperatures. I've had a bunch of different laptops of various brands, and I can only remember one that actually had any sensing of the processor temperature.

I've been browsing around, and I've somewhat discovered that there really are sensors but the something to do with SMbus is hidden by the Bios... ? Am I right?

I can't say, but they're hidden from most diagnostic utilities. :)
