gpu GPU suddenly Overheats

[B-Rex]

Hey,

some time ago my PC suddenly started shutting down when playing COD:MW after a while. I first thought it was the Power Supply but when I checked the temps of the GPU it was around 90°C. When I changed the settings for the cooling fans to almost 100% my PC didn`t shut down, but the temps were still at 70-80° with almost full fan speed and I have a ROG RX480 with three fans. When I took the GPU of another System (RX580 Dual Fan) it got temperatures of about 65-70° with automatic fan speed.

Does anybody know why my GPU suddenly Overheats that bad?

 

Thanks for the help.

 

The PC specs are:

 

CPU: Ryzen 7 1700

GPU: ASUS ROG RX480
RAM: Corsair Vengeance DDR4 32GB

CPU Cooler: Cooler Master Masteliquid 240

PSU; Cooler Master G650M 650W

Does the GPU sag when fitted?

Try and replace the thermal paste, go watch a guide to tearing down your GPU.

A little bit but not much, but it worked before also with sag

Yeah thouht of that, too, but I wanted to ask first if there's another way

Sometimes over time the PCB can warp slightly eventually creating a very small gap between the coldplate and die.

 

Would recommend a tear down, clean and re-paste.

it doesn't look like there's another way honestly. Buy some high quality CPU paste and you'll most definitely see improvement.

no problemo, keep me updated after teardown and paste replacement.

If its sudden, as noted above, the thermal interface material (TIM, thermal paste, etc) has likely dried up and is no longer doing its job well at all
