I recently got my 24" mid-2007 iMac running Mavericks back from my fiancee, intending to try to learn iOS development with Xcode. One of the first things I noticed was that the GPU Diode was running extremely hot. 100C at idle, and 120C when taxing the GPU with XCOM Enemy Unknown. To try and resolve this, I downloaded a couple of fan control programs, SMC Fan Control and Macs Fan Control. Now I'm running at about 80C idle, which still seems high.
After installing both programs, then disabling Macs Fan Control, I noticed that the iMac wouldn't sleep properly. Figuring that was the price I would pay for fan control, I shut down the Mac for the evening. When I powered it on today, it wouldn't start. After I reset the SMC, it booted fine. Is this related to the fan control programs? Anyone else ever have this problem? To sum up, anyone else have suggestions for keeping my Mac cool? I disassembled the iMac and blew the dust out about a year ago, which helped a lot. Should I do that again? Completely taking the thing apart is a real pain. I've also read that Mavericks pushes the GPU really hard, which may account for the high temps. Any suggestions welcome.
