I have this sound coming from my macbook pro for about 2-3 days now.. I just want to make sure it's the fan before I buy a replacement and open up my MBP. Heres a vid http://www.youtube.com/watch?v=lm8Ru7fu2LY When using smcFanControl and I boost the RPM to 6000 on both fans the fan on the right (possible noisy fan) only goes up to 3902 rpm while my other fan goes up to 5772. Theres also a little vibration in the upper right of the MBP.. Is there any other way I can make sure it's the fan? Or can any1 tell if its the fan or possibly the HD?
