I bought a prebuilt msi gaming computer that worked great for about a year, then one day all of a sudden my fps in games would go from 130fps to 15 after about 3 minutes. I noticed my cpu was at 94 degrees. So assuming it was my water cooler that went bad I purchased a new one and installed it and my cpu was still running at 90 on idle. Sent that one back and just ordered a cheap air cooler, finally! Temp went back down to 40 idle. Then after about a week my cpu starts up at 90 again. I have tried new thermal paste on all the coolers and it didn’t help. Anyone have any suggestion?
