So i have a Ryzen 5 3600 and use a Cooler master 212 black edition radiator with a Nocuta NF-F12 PWM 120mm fan mounted on. When im just idle without anything running, my cpu temp is around 35-43 C. Then when im watching youtube or just browsing the internet, it goes up to around 46-58C. Is this normal? I dont have the best case for airflow. I dont know exactly what the case is called but i think its a fractal tower?
