I recently got a new CPU from an FX-8320 to the Ryzen 5 2600 a few months ago. Yesterday I noticed my idle temps were 110+. I opened it up and fixed the problem as whoever screwed my CPU fan on didn't screw it in all the way. I screwed the fan on and got it on all the way and my idle temps are still a little high. (80-90 Celsius) I wasn't sure if I needed to reapply thermal paste or anything like that. I was wondering if anyone might know a fix. It's the stock cooler that comes with the Ryzen 5. Thank you!
