dust always builds up everywhere and can clog up the fan and vents so you should take an air hose and blow it all out. i do this for my cp and my playstion and i still have the first ps4 when they came out. you would be surprized how much less noise you pc will make.

Thing is my PC is clean and there is no dust or very little, just when i play this game my GPU temperature starts rising from 50C to 85C

temperature means usage. Obviously, your hardware is being used hard, thus resulting in excessive heat being generated.
Valheim is NOT light on your system regardless of the seemed visual simplicity. In my opinion, the game was made "low quality" because its so taxing on your hardware. People who ask for "better visuals and more quality textures" just don't understand the consequences of their request.
