Xbox One X overheating alot

The room temperature can effect a console drastically. Try and keep the temp at a regular temp for a while and see if that helps.

It could be that the Vents are being blocked. It could be either dirty or something just in the way. If that doesn't seem to be the problem you might be eligible for a repair request. You can submit one here Xbox
Repair request.

Hope you get it solved.

Hey sorry that you're going through this serious issue. Have you tried to elevate the console and have it in the open area so it can vent out properly? If that doesn't work call Xbox Support and explain to them what you have already experienced and what
was fixed recently. I hope that this helps.

No I havent, it's been in the in the same place all year

I recently opened up my XBox One X to replace my harddrive for an SSD. While I was at it, I replaced the thermal paste. It was pretty much rock solid on my XBox so the heat transfer between the APU and the cooler must have been extremely poor. If you are
comfortable opening it up and replacing the thermal paste, I really recommend you do so.

There are several videos on YouTube that walks you through the process, and the X is really easy to work on.
