Hi. I recently got into some errors with my laptop. I got the question mark screen and what not. It is all fixed. My current problem is that the fan seems to be running anywhere from 4000 to 6000rpm. I've heard the normal rpm it should run is 2000. Knowing that, if it fails or overheats, boom. My laptop is gone. Warranty is up already. I am wondering what is the best way to get through this issue? Should I buy a new fan? If so, where can I buy it from? Links if possible Any tips with this thanks.
