Question about Gigabyte GeForce GTX 1080 Xtreme Gaming Water Cooling

If you want to replace the cooling, it's best to buy Asus cards. As long as you don't do any mechanical damage to the card at Asus (scratches with a screwdriver), the warranty remains valid. You only have to send it in with the original air cooler installed if something goes wrong.

Yes, everything works but the warranty is goodbye.
