okay so i have been reading about and seeing alot of people putting aftermarket coolers on their new and fairly expensive video cards..... does this void the warranty on the card? I know in the past cards came with plastic clips on them that you really couldnt get off w/o damaging the clips.... now i notice the are actually screwed on... thus making the changing of the cooler quite easy. i was wanting to know cause i was thinking about purchasing a new cooler for my card but aint no way i want to risk voiding the warranty incase i want to step up to the new 9xxx cards when released.
