So I have an i9 9900k and had a cooler on it from EVGA, replaced it with a Corsair H100i and all is fine except that my temps are all over the place while using HWMonitor. I ran Lightroom and the PC restarted, take it temps got too hot. I put a small pea sized thermal paste and all, making sure all connections were good. Temps at idle are about 30 Celsius. Thoughts?
