I recently disassembled my PS4, model 1215a, to clean it and reapply thermal paste (Arctic MX-4). When I got it together I played it for a couple hours to make sure everything was good but I noticed the fan is now quieter than it was when it was new. I can still hear it and feel the air it’s moving but even playing for a couple hours it doesn’t spin up much. It hasn’t overheated but the fan just seems too quiet now, should I be worried or is this normal? This is the first time I’ve taken my PS4 apart but had done the same thing with my PS3 prior (cecha01).
Thats normal lol… You replaced the thermal paste, you should expect it to be quieter.
