I recently had a 1070 fail. One of the fans stopped and it wouldn't produce video. Tried to clean the fans following an online video.
Unfortunately that didn't help at all.
BUT IT WAS SO DAMN STRESSFUL PULLING APART.
Thermal pads tearing, exact spacing required unknown, dangers to circuit boards, and slips all contribute to fear of ruining a video card.
Does anyone know a service that does card rehab? Replace all the pads and fans?
