Xbox One Fan Starts and Stops

Hello there.

I have a problem with my Xbox One Original console, and it is with the fan.

I’ve cleaned the whole Xbox, put new thermal paste, cleaned all dust inside and outside.

Console worked fine until it went to Sleep Mode while Downloading a game (my cat did not peed on the motherboard, yet).

Fan tries to start, but it is like he doesnt have enough power in it. I’ve plugged all cables inside again, and nothing happens.

I repeat it worked all normally, I tried unplugging adapter from the power and same problem.

Here is the problem: www streamable com /hm02di

Thank you.

Please? :confused: Still same problem.

It releases some buzzing from motherboard when it is in standby mode.
