I got SpeedFan and saw my fans weren't on.

They are connected correctly and Precision says they are off also.
What do I do?

??? 120C, what core do you have!? the fail-safe is 100c then it shuts down automatically.
open your case and with one finger try very lightly to move your heatsink, if it's moving more then say hlf a cm then turn off your computer, unplug, and remount the fan. if that doesn't fix it well, i guess you need a new fan also.
EDIT: i also have speedfan but i dont a "CPU" displayed on mine, just the 2 cores.
