So I have been dealing with my CPU overheating for a few months and haven't been able to find any solution. I can't count how many times I have reapplied thermal paste. So recently though I have isolated the issue to my liquid cooler. Originally I accidently bumped the tubes and my temps went down then slowly back up. So I tapped them again harder and my temps went down and stayed down. Until I turned my computer off then same problem. So today I went and while it was runnig I jiggled the radiator and bumped the tubes a few times and everything seems to be OK even after turning it off. Thanks for reading that and my question is, is it likely to be an air bubble and since I don't think it would have anywhere to go is this going to turn into an ongoing issue? or what could it have been? Thanks again for reading that text wall and have a great day.
