I was about to slap an aftermarket heatsink on an XFX 6870 when I noticed the tamper stickers on the heatsink screws. It's the first time I've run into those on a GPU in a while, but I've mostly been modding more downmarket stuff that isn't worth putting stickers on.
Anyways, are there any GPU vendors that explicitly allow aftermarketing heatsinks to be installed without voiding the warranty? Or at the very least, are there any ones that don't put tamper stickers on the things?
If anyone has a 6870 and can take a look at it to see if there's any visual tamper indicators, I'd appreciate it.
