GPU is toast? Tried reheating soldering points
I had green square artifacts on my iMac, and I read about being able to heat the gpu to reflow the soldering points.
The iMac started up just fine before, aside from the artifacts.
I heated the gpu with a creme brulee toaster (open fire) and used an IR thermometer to monitor the heat. Probably heated for 20 minutes until the GPU reached 210-215 degrees C. (420F) I had aluminum foil around the gpu and had cut open so the gpu was exposed.
Now the screen is black, and the fan is running on low speed when I try to start it. No start up chime either. Is the GPU toast?
I think I probably went too high, heres a pic (underneath unfortunately, heated on top of the gpu only)
It is a discrete card.
Will this gpu fit my iMac? Is it worthwile replacing it?
