to effectively cool the Graphics Card, you will need:
* somehow to attach the block/pump to the the GPU
* preferably put some heatsinks on the vRAM
* MUST put some cooling on the VRM.
All of the above are not really "beginners" tasks. So proceed carefully.
Instead of wasting your money on shinny/blingy (crap coolers) toys like NZXT/Corsair/Arctic, invest in more appropriate solution like:
* EK Predator - probably the most convenient
* Swiftech H220 - probably the best performer and smallest footprint
* Alphacool eisbaer and eiswolf
All of the above are:
* reasonably priced starting at 110-160$
* made of "enthusiast grade" components - basically a preassembled custom loop.
* customizable and expandable
