Graphic card overheating, CPU fan in full speed, then black screenI am a newbie to Mac and this forum, so please be gentle. I recently acquired an early 2008 iMac A1225, EMC 2211 - 2.8GHz CPU...
Answer to: Overheating , fans running high , shuts screen off after 15 minsDarren, the only way to permanently fix the symptom is replacing the video card. I can confirm this because I just replaced my video card. I do not have GPU overheating issue any more. I have been watching full HD online movies for several days (stress test for the card), the overheating issue is gone. The highest GPU die temperature is 61C, normally it is around 50C without online videos. Before replacing the card, my old card can easily reach 128C in completely idle. I have been trying many ways to fix the old one, however none of them worked. Ways I have tried: - replacing GPU heat sink compound - adding an extra heat sink to GPU - removing air wall under GPU - reflowing GPU (the GPU died after this, don't try)
