Very high idle temps on Ryzen 3700x
I Was using Ryzen 3700x on 3800MHz and having 35-37 idle temps. Today I've discovered that my temps with same voltage and clock speeds are 47-50 now. On 4.2 MHz my idle is around 60 now (was 45-52 before). I'm using Noctua DH-14, And Aorus X570 Elite motherboard. Cooler works in balanced mode, now around 1000-1020 RPM
I've changed nothing in the system, no new software either. I've already update my BIOS (from F3 to F11) and nothing changed. I've changed Windows power mods and it didn't help me to.
Anything that I can do to fix it?
