Heatsink Fan getting loud
So 2 days ago 5/19/20 my heatsink started making noise and i don't know why. i have a AMD Ryzen 7 3700x. and im using the heatsink that comes with it. At first i thought it was dirty so i pulled it off and used an air duster to clean it and replaced the thermal paste and put it back on the same way i took it off. but when i turned my PC on it just began to ramp up again. i went into the bios to try something there and i also downloaded fan control but i don't know what to do. i built my PC but i am not by any means a tech expert. Can anyone give me any insight or info of what it could be? Thanks
