both fans had audible clicking the genus's couldn't hear it..

My Problem

my macbook has just turned 3 and the fans actually started making noise at 2.5 years but tolerable took in to apple 2 weeks before applecare expires but they find nothing...

My Fix

i ordered the fans from IFIXIT replaced them within 15 minutes and now i have silence

My Advice

this is such an easy replacement and now my macbook is good as new.
