Fan tries to spin but it can't
My PS4 is presenting a blue screen with the overheating warninng, and then shuts down.
I exchanged the thermal past but, later, I saw that the fan wasn’t working. It tries to spin, twitches a little bit, but stops. It’s spinning freely when I try to help with my hand, however when it doesn’t work at all.
My question is: How would I know if the problem is either the fan, actually or the motherboard connection. Or even the power supply.
I couldn’t find any scenarios like mine in the internet.
Thank you for the help!!
