My CPU fan has been acting up for a few weeks, and its kind of annoying, After turning my PC on it takes the fan 30+ minutes for the RPM to get to the normal 2800 - 2900. It sits around 1000 - 1500 RPM. And once it reaches the 2800+ point it only stays there for around 12 hours, compared to before it would stay at a normal RPM for however long my PC was on. Is there a solution to this other than obviously getting a new CPU cooler? My current cooler has a 3 pin connector thats all I can really say because im not the best with hardware stuff. TY for any help.
