Why 2011 iMac GPUs Fail

The discrete AMD GPUs in 2011 iMacs run hot over years of service. Repeated thermal cycling creates micro‑cracks in solder joints and stresses VRAM. Dust build‑up and dried thermal paste aggravate the problem until the system shows artifacts or won’t boot.

What We Do Differently

Isolate fault: GPU core vs. VRAM vs. power rails
Reball or replace GPU with correct revision
Replace thermal pads/paste with high‑quality materials
Clean heatsink and verify fan curves/sensors
Stress‑test (graphics and thermal) before hand‑off
