Original Xbox Xbox randomly shuts off

[Asher]

So recently for the past 3 or so weeks I've been having a problem with my Xbox One where it makes sort of a chirping sound and after 20mins to an hour of playing it turns off, i disassembled it and replaced the fan but it still turns off, it is at least 2 inches from everything around it and is getting proper ventilation but i still don't know what the problem is, if someone can help me please do.
