Recently the fan on my macbook pro has been running loudly. I blew the dust out of it however the noise is still there. I'm figuring its probably a bad bearing or something and the whole fan needs to be replace. However, upon doing some research online for a new fan, i find that most places only sell the left and or right fan. My 15" inch macbook pro only has one. Does anyone know were i could get a new fan for this thing? I got it in late 2009 and the model number is (A1286) Any help would be appreciated. Thanx
