10.5: More control of fan speeds on iMacs and laptops
Authored by: Graeme_Smith on Jul 17, '08 10:14:49AM

So can machines actually get ruined due to running to hot? Is this an issue one should actually worry about? I've noticed my iMac (aluminum) gets very hot on top but I assumed they were meant to run that way and that Apple had everything under control...

Yes. All other things being equal, the hotter a system and its components run, the short its life. While this is not a practical concern at some temperatures, modern-day systems are quite capable of generating enough heat to significantly shorten their lives. See another reply for additional comments.

Personally, I think that something like Fan Control should be part of Mac OS X.

BTW, on my old PowerBook G4 the excessive heat fried the optical drive connector (it couldn't write DVDs anymore) and the firewire ports. On the new MacBook Pro I always try to keep the temperature as low as possible (reasonably)
