AHT would be on a separate Disc in the original set.

There aren't many sensors in them, but...

Temperature Monitor...

iStat Menus...

And/or iStat Pro...

Have you reset the PMU? That can sometimes help with fan issues:

Unplug all cables from the computer, including the power cord.
Wait 10 seconds.
Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
Let go of the power button.
Press the power button once more to start up your Mac mini.
