My Macbook Pro just started making a strange sound today.. heres a vid I recorded with cycorder.. does anyone have any idea what it could be? http://www.youtube.com/watch?v=Jum95rBvPfM Does anyone know what this is? It sounds like its on the right side.. could it be the fan? and if it is.. is it possible for me to fix myself? I work from my computer and I really need this fixed as soon as possible..
