I'm trying to figure out what actually voids my warranty on ASUS 4850. I've gone to the Asus website (terrible) and found the grounds for "no-repair". The information included with my video card is out of date (claims that I only have one DVI port) and I can't really find more info. I've tried searching the forum but can't find a search that returns specific Asus information. But the basic question is does removing the heatsink / fan void my warranty, especially since I've read that these cards can have problems.
