Computer overheats and then dies.
I bought a flex subscription from NZXT. The computer was working fine for 6 months. Now the computer doesnt stay on very long before it overheats and shuts down. (Maybe 5 mins if I am lucky.) I reached out to their support and of course it said it could be a few days before I hear back. The cpu temp quickly gets to 115⁰ and then shuts down. I have made sure all vents are cleared and dust free. All fans turn on and run at max speed right away. The aio pump seems to be running. I can feel liquid running through both pipes. One stays pretty cold, the other is warm. I replaced the thermal paste and made sure the pump was securely against the cpu. It made no difference. After only a few minutes it shuts down. No load or anything running. At max it has like 12% cpu usage while sitting idle. Any suggestions on things I could troubleshoot or look into first until I hear back from their support? Thanks.
