I have owned a G5 Powermac Dual 1.8 for about 4 years. And in that time I haven't had any problems with the fan. It very rarely came on and only on very hot days.
I recently updated my OS to 10.4.11 and after installation the fan went ballistic. Now my fan comes on and revs up to frightening speeds several times a day. Surely this cant be normal.
Does anyone have any advice on what could be happening and how I may be able to solve it? Preferably without an expensive trip to Apple.
Thanks in advance.
