I built my first pc today. Everything went fine until I turned it on for the first time. I noticed my wraith prism cooler was loud. So I installed core temp to check the temperature of my cpu. It showed 50 on idle. I immediately removed my cooler and reapplied new thermal paste and installed my cooler once again. This time idle temp went to 30+ degrees but for some reason it kept going from 30 to 45 every second. I thought ok maybe this is normal. Then I closed the glass panel of my case and a new problem started, my cpu temp went to 70+ degrees. I opened the glass panel again then the temps dropped. I don't know what I am doing wrong. I checked if I installed the wraith prism cooler in correct way, it looks like I did. It stays in place. Please help I don't want to ruin my first build
