Xbox eventually overheats and crashes games.

Alright, good afternoon everyone. I have a problem on my hands and I truly long for a solution here. So going back a year, I bought an used Xbox 1 off of ebay for a fair price. The xbox wasn't broken, there wern't any issues (besides the one I'm bringing
up), and the owner barely used it extensively. I managed to play multiple games perfectly on it and managed to streamroll through multiple games like COD WW2 Campaign, Overwatch, Watchdogs, City skylines, etc. It was only until I got to
playing GTA online where I noticed this issue occur constantly. Basically everytime I log on to GTA online, I would be able to have a solid 10-20 minutes of playtime before my Xbox crashed the game without any issue warnings/signs. If you
hear the audio basically all you hear when it crashes is a low pitch-yet loud buzzing sound. Then your frame would freeze up for 5 seconds and then you would be yeeted into the home screen. THis sucks when you are doing sell missions for your businesses and
you end up having the game crash half-way through selling, causing you to lose profit margins, and causing you to lose money. I cannot stress how often this happens, and it has gone to the point where I can't enjoy playing GTA online in peace because I am
constantly paranoid of when the game is going to crash. However, I finished the whole GTA 5 campaign without noticeable crashing.
It's only when I play GTA Online where it crashes. I assume it is a hardware issue as it looks like it is Overheating every time I play. Touching the ventilation vents also prove that hypothesis. Anyways, does anyone have any tips
for these overheating issues? I really don't want to buy a new Xbox to solve this issue, and I don't mind getting a hands-on experience to tinker with the xbox to potentially switch out parts, or replace items. So if anyone reading this has an idea of what
the heck is going on, and If I could potentially open up the Xbox's interior to replace fans, or the CPU thermal paste, etc, that would be very much appreciated. Thank you for your time

Sincerely, A very distressed gamer.
