I recently built my first rig and am having issues with my cpu core temp. The CPU runs at 50C idle, and under load it spikes to 100C. As soon as I saw it spike to 100C I stopped the load test and it went right back to 50C. I’m using an i9 9900k cooled with a Corsair h100i pro. When I first started the system I heard crackling coming from cpu area for 15 seconds. I assumed the sound was melting of the pre applied thermal paste. Any ideas on trouble shooting?
