O.T. Reading computer internals - designnut - 10-13-2011

I have a program called AIDA64 that looks deep into my dcomputer (free trial). I reads ttemperatures voltages and CPU watts in use.
It is a locally built-up, not a name brand. Any idea what it uses to read all that informattion?

All modern CPUs have internal temperature sensors so that they can throttle clock speed and/or voltage to keep it within its thermal envelope.

Most current motherboards have various flavors of "super I/O" chips (Fintek makes some) that can control and report on these values. AIDA64 checks for a number of these chips and probably combines information from them with information from the CPU.
