Its a Core 2 Duo Mac Mini running Leopard.
Everytime, from the second it powers up it runs the fans at 5200rpm (full) -- I've tried resetting the PRAM, resetting the power (where you plug it in with just power cord ...) and even limiting the fan speed with Fan Control -- the fan still runs at full.
Even if I limit the fan in Fan Control to 1200 rpm, it still runs it at 5200.
Any ideas?
