The other day I took apart my PS4 and replaced the thermal paste on the CPU/GPU. I've been replaying Monster Hunter and right from the opening menu the fan has been on takeoff mode, now it's barely even audible. It's so quiet now that I was worried I'd broken the fan at first. The thermal paste was a sorry state before, but it's a day 1 PS4 so it's done it's job.
