I've created this topic to list AMD/Nvidia GPU manufacturers that you should buy from if you are the type of person who wants to remove the heatsink to clean it or replace the heatsink with a liquid cooling waterblock
Also inside this topic is the list of AMD/Nvidia GPU manufacturers that you should avoid for the same reason as above
Included is a screenshot of my discussion with each manufacturers to ask where they stand on this matter

Important Note: This does not cover if you cause physical damage/water damage to the GPU

GPU Manufacturers You Should Buy From:
Zotac - Does not void warranty for removing the heatsink


MSI - Does not void warranty for removing the heatsink


Gigabyte / Aorus - Does not void void warranty for removing the heatsink

GPU Manufacturers To Avoid:

AsRock, XFX, EVGA & Palit pending for their reply

1. Can you please not quote the whole post? At least remove the images so your quote won't be too long
2. Why the judgement? I did say this list is about manufacturers who allow their users to remove the heatsink to clean it and replace it with liquid cooling waterblock

I spilt water (distilled which is non conductive) all over my GTX 1080. Dried off with towel and working fine.

Much later on, 2 of the AC coupling caps deteriorated prolly due to the lousy asrock board that i was running. This resulted in the card stuck in x4 mode and randomly crashing the PC.
Removed the caps and bought replacement from element11 for RM2 (10 pcs).

All of the above learnt on my own over the years and from destroying my own stuff. Like blowing PSU (iCute 450W) running volt-modded 4850.

My point is, if one can afford it and should they choose to do insane shit to their stuff, they should know the risks and also deal with consequences.
And i strongly encourage everyone to do so!
edit: Oh! and thanks OP for this useful info. will help in future purchases.
