I can confirm that I had a bad GPU heat pipe in my 24” 2007 iMac. The GPU would regularly hit 100ºC when doing anything remotely stressful. Rather than fix it, I compensated by using Macs Fan Control. It didn’t fix the problem, but got enough air flow going inside the chassis to keep the GPU from melting into a puddle. The iMac eventually died from a bad PSU. RIP. Eric -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
