after i updated bios, and the moment i load into windows, my cooler ramps up fast and i look at hwmonitor and im at 90+ degrees on my cpu and then after around 30 seconds it goes back down to normal temps.
it wasnt doing this beforehand
We're going to need a little more information. Which BIOS version are you currently on and what OS version are you working with as well? You might want to keep a bootable USB installer(made using Windows Media Creation Tools) handy while also backing up any and/or all critical content in case you need t reinstall your OS.
