My 2010 MBP fans suddenly started making a really loud noise (like a hair trimmer) and it doesn't stop. The CPU temperature is at about 45° right now and both fans are only spinning at about 2000. I've tried quitting every running app, restarting and even resetting SMC. Please help, thank you!
Got a tip for us?

I would wager that theres some sort of debris in or around the fans. If something is lightly touching the fan blades as they spin you will easily get a loud whirring/buzzing sound. You might pull the bottom case off, possibly remove the fan/s as well, and blow a bit of compressed air around the fan areas.
