When I start up the PS4 there is some air movement so I know that fan is moving, but it never gets faster. It also does not overheat and shutoff. I’ve replaced the fan and thermal paste to try and resolve this issue, but that did not do the trick.

Hi! If the PS4 does not overheat, you don’t need to worry about it. If you don’t trust it at all, you could place a sensor to check the temperature. Important to know, where is the PS4 located?
