Small note... you pay for the cooling block, that means you'll need to order your own fittings / barbs and clamps, do not forget that. Also get some extra and good quality thermal paste.

GPU block Installation

It is always a little weird to completely disassemble a 500 USD product just for some better cooling, but believe me when I say that it is worth it. Let's remove that cooler shall we?

First off, remove all screws on the backside of the graphics card. Now here's the first tip, have a proper quality screwdriver, you'll need a mini-Philips screwdriver, preferably hardened steel from say a brand like Stanley. The screws are secured with blue Loctite and my man... the screws are mounted tight and secure alright! You will probably need to apply some force and I actually destroyed some screwdrivers here as the heads got damaged.

Now before you try to take off that cooler, do not forget on the front side there are two screws that need to be removed as well.
