High idle temperatures on the Ryzen 7 3800X are common.
Related specifications: Ryzen 7 3800x, Xigmatek Aurora 240mm AIO, B550 Gaming Edge Wi-Fi, strong airflow.
With my 3800x I reach about 42-45°C during idle, climbing to 55-60°C when launching programs, sometimes up to 65°C. In games it stays around 59-61°C, but can hit 70°C under heavy CPU load. In Cinebench R20 it reaches 85°C (110W), while AIDA64 shows 65-70°C.
I’m considering lowering the voltage but haven’t noticed any thermal throttling. I prefer not to set static voltages/frequencies because I think it’s harmful. These temps are unusually high for a 240mm AIO. I’ve heard people achieve 9900K at 60-65°C with similar CPUs or others.
I cleaned the thermal paste with a paper towel and used MX-4 paste, changed the rad position (reduced temperature by 4°C), reset BIOS (it’s up-to-date), used AMD Balanced power plan and updated drivers. Nothing helped.
I didn’t install the backplate for the AIO, but I’m wondering if it significantly impacts cooling. Should I try re-mounting it? If yes, I’d like to do this as the final option since it would be quite time-consuming.
Ryzen third gen often faced issues with high idle times. However, as long as temperatures stay normal, it should be fine.
