Xbox series x fan not spinning while in instant on mode

Kindly reset your console to factory default keeping your games and apps to remove any corrupted file that may be causing the issue.

Don't worry because as long as you're connected to Xbox Live your saved progress, games, will not be deleted. It will remove all of your accounts but you can add all of them later on.

Press the Xbox button to open the guide.

Select Profile & system > Settings > System > Console info.

Select Reset console.

Reset and keep my games & apps.

If the steps worked it means that it just needs to be reset and nothing is wrong with your Xbox console.

It can be corrupted system data as well which can be fixed by resetting the console that's why we need to perform a step by step troubleshooting steps to get to the bottom of the issue.

How It can be done or use that what you suggested in the previous comment?

That's indeed alarming. It can be a hardware problem but we just need to perform troubleshooting steps to isolate what is causing the issue.

I cant do it right now but what I did when I found out this morming , I turned It on and Its working. My problem its not that it doesnt work the fan, It Is that while in stand by, obviously if i get closer my ear (20cm from the console) I can hear the console working and if I let It in this state for all night, in the morning I find It warm but the fan not spinning to cool down.

Before almost has Always spinned the fan or the console was cold.

Yesterday a noted that even the logo at cold start doesnt appear.

Can they Be caused by the latest update or they are hardware problem?
