What software do you prefer that displays the current processor or system temperature of your computer?

I've tried a couple different programs, but either they are not accurate, or they don't detect a lot of system's chipsets.

Looking for a really good one. (for Windows)

SpeedFan or Everest.

I can get the readings directly out of /sys, and can easily build
a better interface around it.

Which I did. I made fvwm menus for CPU frequency and fan
speed, both of which also provide relevant readings.
