I have a 24"Aluminum iMac, of mid-2007 vintage I believe. After a few months, I started running games on it in Windows - and promptly encountered video artifacting. After much research, I found that overheating was the cause of the problem. Installing fan control software, like smcfancontrol and Input Remapper allowed me to crank up the fan and prevent video anomalies. Lately though, the wireless began cutting out and I noticed high temperatures. I raised the fan speed, and the problem went away for now, but I seem to have some "thermal creep"going in.
I assume this is due to dust build up on the inside of the iMac, in addition to whatever problem originally existed (too much thermal paste, perhaps?) The obvious solution is to blow out the inside of the iMac and perhaps apply new thermal paste to whatever heatsinks lurk on the inside. How difficult is working on the inside of an iMac? I have worked on dozens, if not hundreds, of PCs and PowerMacs, but working on laptops always makes me twitch. How much potential is there for error in disassembling, blowing out and re-pasting an Intel iMac? As an aside, how much would it be worth as I sold it as-is as a fixer- upper? -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
