It might be your vrm on the motherboard overheating. Tone down the voltage and frequency to see if that changes anything

What is max CPU/GPU temp? What exact model of PSU do you have? How much RAM?

cpu temp 35% and gpu 30%

What utility are you using to measure temperature? It should °C, not %. I use HWiNFO64 (run "sensors only"). What is your room temperature?
