Why bother for warranty ? it could take weeks at best. i'd be bothered ship my card just for replacement fan, in mining time is $$. Just take a look at this https://www.youtube.com/watch?v=-yQHAMz1v5g
Its had a hard time, it comes apart to be cleaned often and I couldn't be bothered to put all the screws back in it.
It runs fine except the failing fan
