Hi all - my first post so be gentle I just bought a couple of fans from the bay for my Macbook Pro. No real reason other than I'm looking to sell it soon and want to make sure the fans don't give out just after a sale! Anyway - the fans arrive which were specified for my machine. However - the left side fan has a faint but distinct rattle when my machine is slightly inclined - and the right side fan doesn't even fit properly. What's more the right side fan has some paint chips to the edges - and a part missing 'warranty void if removed' sticker. They came in unsealed 'zip' bags. Pictures below. Should these have come in sealed bags - and what about the warranty sticker? They came from a company with a very high feedback rating on the bay - but I would like some opinions as I'm just about sick of some sellers trying it on... Thanks!
