NOTE: The video card should be removed from the chassis in order to install this cooling device. Most cards using the VID-series blocks are disassembled the same way, although heat sink assemblies of any given model can vary.
CAUTION: Removal of the original heat sink or liquid cooling may void your manufacturer’s hardware warranty. Please consult the manufac-

turer if unsure, and keep all original parts in case of a return/RMA.
There are several small screws around the edges of the plastic fan enclosure. Remove these to open the outer half of the fan enclosure.

Remove both copper GPU heat sinks by unscrewing their 4 large mounting screws.
With all screws removed, carefully remove the larger heat sink frame. Original thermal paste may present resistance during removal.
Unplug the heat sink fan wire. Remove the original RAM thermal transfer material, and wipe any residual thermal material from the main GPU chipsets.
All heat sink assembly screws should be removed. There should be about 19 of these on the back of the video card, and 2 more on the rear L-bracket.

The thermal pad sheet should be cut into pieces required for your video block contact
areas. Please use the diagram included with your water block to determine the approximate sizes that will be needed.
Basically, any area of the video card in contact with the original heat sink will need new heat transfer material. Place heat transfer pads on the corresponding areas of the Koolance water block.
Thermal paste is only required on the main GPU’s. The other areas will utilize the included heat transfer pads.
Spread thermal compound on the GPU’s thinly and evenly using the included paste packet, or a piece of thick paper (such as a business card).
Different sets of heat transfer pads may be included. Each set has a different thickness, and one should be chosen that offers best contact with your video card.
Gray thermal pads have plastic film on both sides that must be removed before application. White/Pink thermal pads only have plastic film on one side (white) that must be removed. Do this after cutting the proper shapes.

Tighten each screw on the reverse side of the card. If the
original video card screws do not fit, use the Koolance­supplied screws and plastic insulating washers. Original video card rear brackets or back plates can be used if they still allow the water block to be mounted.
Place the Koolance block onto the video card so the mounting screws will align.
Socket plugs are included with the VID coolers which must be placed opposite the desired nozzle locations.
G 1/4 BSP inlet/outlet nozzles can be screwed into the top or bottom side of the cooler, as long as coolant flows from one half to the other (left to right or right to left).
Connecting Multiple VID Coolers
When connecting multiple VID coolers, Koolance offers an optional direct-connect nozzle. This minimizes liquid routing while avoiding potential conflicts with hardware in between the video cards.

One Slot (CNT-VDA2) Video Connectors
