13" 2010 MBP fans malfunctioning. It literally sounds like a weed wacker is running in my computer . Its embarrassing too I'll be in class and the fans will randomly start doing it! Its random too! it sounds like they have something stuck in them because they get really loud then a loud ping occurs and the exhaust drops to literally <50rpms...I thought it was my hard drive at first but it has to be the fans...I downloaded an app to try and better manage the heat by controlling fan speed but its still a problem...like when I would encode video I would bump up the rpm's from Apples default of 2000 to 2800 and watch the heat..if it got too hott I would bump the exhaust up to 5500+ RPM's and the CPU would cool down in seconds...but like today the fans briefly locked up completely...scary moment as my CPU was at about 190ºF and my computer just shut down! Thank God it shut down so quickly as the temperature was climbing pretty high and I don't need to fry my CPU! So genius bar appointment? Is there anyway to clean out the fans without voiding my warranty?
