[QUOTE="chas_m, post: 1146488"] Actually, this (and other forums) mostly reveal the imperfections of users -- myself included -- not the Macs. Actual hardware defects that aren't one-offs unique to that user (or caused by the user) are still pretty darn rare. No, it's not. You just don't know anything (yet) about Apple's ventilation designs. You didn't read the link provided, did you? If your machine was actually "overheating," it would shut off. If it hasn't shut itself off, it is -- ipso facto -- not overheating. That would be perfectly normal. See my response above ... you're just unaware of Apple's cooling design for the iMac (and, to be fair, there's nothing on the box that explains it). The iMac uses "convection cooling" (aka "heat rises") to keep fan use (and thus noise) to a minimum -- and the vent on the top is doing exactly and precisely what it was designed to do -- vent hot air. In other words, it is supposed to get hot. And your hand is not supposed to be there. :) It's an innovative design compared to the rest of the computer world, but its just plain clever. Cool air is drawn in by convection from the bottom of the screen, passes over the components and warms up, which causes it to rise and vent out the slot in the back with an absolute minimum amount of "helping" by the fan system (which is computer-controlled to kick in only WHEN and exactly HOW MUCH its needed). Ingenious. But don't take my word for it ... ask Bobtomay or any other other people with more green dots under their name than I have. Or you could just read the link I provided in my previous post, it's all there. [/QUOTE]
