Hiya, The fans started screaming on my MBP during a bit of light mid-afternoon web surfing (damn flash adverts...) then noticed it was only the right hand fan. Fired up iStat and it's showing 6000rpm on the right and 0 rpm on the left. Given it a restart etc and it's still the same. I guess the left hand fan has failed. Anyone know a way of confirming this with some diagnostics in case something else more expensive has failed? I'd also appreciate any suggestions of where I can get the replacement part in the UK. Taa muchly in advance.
