Hello, I recently built a PC with Ryzen 3 2200G. When I connected the HDMI to my TV to use it as monitor it booted correctly... The BIOS was reporting that my processor was at 41-42 C while being idle... Without installing any kind of drivers i decided to download a game to test it. Beside the low framerate that was about 5fps, I switched to ryzen master and saw that the processor has reached 80-83 C.. I tried many temperature monitors and programs but they all show the same... I have the stock cooler which I don't know if I installed it, having a kind of plastic protection for the thermal paste, or if i have to add more..
had the same issue as you dont put toothpaste on it buy more thermal compound like arctix mx4 and you will be fine and put a pea size one on dont spread it to and just put the cpu back onto place and your good to go.
