I ordered a part and got it. Great Job.
The water block has a fantastic look if you can figure out how to assemble it around your video card. It comes with lots of extra screws. Most of which look like are not needed. The one important item is missing is an assembly guide. There was none in the box.
An assembly instruction diagram is shown in the product image gallery, although the proper locations for the thermal pads may not be totally clear. They should be applied to the mosfets and VRAM on the card. The GPU core should have thermal paste applied to it. Pre-spreading the paste to ensure full coverage of the die is recommended, as any part of the die not having thermal paste spread onto it could result in damage to it. The screws and washers should be used as shown in the diagram.
GPU runs 20 degrees C cooler than with original fans, and the RGB looks good. (GPU mounted vertically with riser.) My only issue is with Corsair, not Bykski. It took two sets of adapter cables to get the RGB to the Corsair Core Commander. It would be great if Bykski would make a Corsair specific cable available.
First time building a water-cooling system. Bykski.us was the only company who made a block for my gpu. I am very happy. The order was shipped on time, and it arrived quickly. I have not installed it yet. Will give update. So-far so-good. :)
The pump is very quiet pumps liquid extremely well and the LEDs look great.
