i was with ReV:-O on tuesday when one of his fans failed... it seemed totally random... no debris, no obvious broken conections... and he wasn't even bashing it hard ;) just some wimpy jumps... and a few crash's
upgrading to a different fan should help...

try that one...
if you do go for it, just plug it into your reciever... i would guess the power regulator to the fan has gons (is it on a different branch to the bec?) because the fans arent mechanically damaged in any way... just seem to be fried...
oh and if you get one... order me one too ;) i'll get it off you next bash
