Does SETI, Folding, etc. make your processor life shorter? All that time at ~100% usage can't be good for it...or for the machine for that matter... This is just a general question. My G4 is cooled w/ a Delta fan, Swiftech Heatsink, and Arctic Silver thermal paste. As for the internal, it's like constantly ripping a CD. I'm afraid of breaking my processor keeping it on all the time, it's just a couple months old. Thanks for your feedback.
