CPU runs hot since update to 7.0.1

Hi, As the title says I updated from 6.12.15 to 7.0.1 yesterday, everything seems to be working but my cpu that before idled around 40-45C now won’t cool below 50C and sometimes hits 70C now! The temperature also seems to be quite jumpy one second it’s around 38C the next it’s at 65C, Didn’t change my Noctua cooler or the settings of the fancurve. Any idea what might cause this?
