[QUOTE="pm-r, post: 1807178, member: 175845"] And of course Apple sets the temperature and the fan speed to prolong the life of the Mac and of course they wouldn't want you to have to buy a new one sooner than expected — THEIR expected time!!! I have come across some users iMacs as well as our own, that ran so hot you could not keep your hand on the top left of the display just during normal use. The fan speed control software fixed that problem and I don't know of any user who has had to replace a fan in their iMac, and that even includes our own oldest 2007 24" iMac still gets used daily. BTW: Here's a older summary of fan life at different temperatures: Sintec sleeve: 45'000h @ 20oC; 15'000h @ 60oC Superflo: 50'000h @ 40oC Ball: 70'000h @ 40oC; 40'000h @ 25oC HydroWave: 50'000h @ 40oC Note: 1 year = 8766 hours. Quite a drastic difference I'd say. I'll go with running ours at a cooler temperature thanks, and especially when considering that heat is all electronics worst enemy for all components. I'd say [I][B]Think Cooler[/B][/I]!! :Smirk: - Patrick ====== [/QUOTE]
