How can I get some help?

Make sure your Xbox is somewhere well ventilated so the fans aren't blocked. Also make sure you keep it dust free-- another thing that may help is vacuuming the vent- a small vacuum that you can buy that is used to vacuum out computer towers and vents
on small electronics like small game soles will work best because it is designed not to harm electronic equipment but a Dustbuster hand vac will also work

You know of any ways how to actually cleaning it out? sounds horrible.

Hi, if you are speaking about the 1$/€ gamepass ultimate for 3 months the promotion is valid for all the users only for their first subscription to gamepass ultimate, therefore if you never had a GP ultimate subscription it should be valid for you till january
6th also if you have other active gamepass or gold subscription (they will be converted and merged to ultimate, more info here). Have you tried opening the promotion with
your account? It should show you the final conversion and how much will you pay

If you have already been a GP ultimate subscriber in the past the promotion is not valid for you

Hi there G Doub1e U

It sounds like the fan might be having issues on the console, but how to fix issue means it might be sent way to get console repaired.

Hello. Well, another alternative would be to use the Support form on Xbox.com. That form you just got to fill out your problem and the rep will get back to you. I am not quite certain if they still have live agents there, but you can try that if the phone
service does not work for you.
