Really?

What happened and why?
TBH I seen a sh1t ton of people WC their GPU with these type of WC similar to those typical CPU WC
It burnt his VRM and VRAM as it went into service centre as there is tons lots of artifact showing around.
The 92mm fan could not cool the VRM sections. It isnt enough and its very hot. It went over 100deg. And it will throttle further.
As for the VRAM section, there is nothing to protect it from overheating.
There are people whom get away with it. Yes, for instance you buy GPU with strap on VRMS heatsinks. Then yes you could buy it and get it cooled.
But however most 970 VRMS are located at the back of the card instead of the front. So the g10 is out of the question to fit it.
