My XboxOne has just started completely powering off without warning. It has just started recently after starting to play Madden 19. I have had it for years with no issues. I noticed that the top of the Xbox was pretty hot, so I decided to try this out. It did nothing for my problem. The Xbox still shut down after 30 minutes of use, and the top of the xbox and the top of the fan were both hot. Of course this could be a more serious issue with my Xbox, but this fan really did nothing to cool down my Xbox at all.
