Chosen Solution

I just replaced my old fan with a new one. But when I turn my PS4 on, the fan keeps increasing speed until it is VERY loud. At it’s climax, the PS4 shuts off completely. This happens within a timespand of 10 seconds immediately after turning my PS4 on. It’s like the fan doesn’t know when to slow down, but maybe I accidentally made a mistake with the wiring when putting my PS4 back together? Please help!

sounds like you dont have the heat sink clamp on tight enough
