Koolance VID-NXTTN2-R User Manual

VID-NXTTN Installation Guide v 1.0

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.

All heat sink assembly screws should be removed. There are multiple screws on the rear of the video card, and 2 more on the L-bracket.

GTX TITAN Disassembly Screws (Bottom and Rear L-Bracket)

With all screws removed, carefully remove the GPU heat

sink, followed by the card heat sink. Original thermal paste may present resistance during removal.

Use the shortest provided screw with a nut and washer to secure the PCI bracket to the top corner of the video card. The bracket will be loose after removing the original heat sink.

Thermal paste is only required on the main GPU. The other areas will utilize the included heat transfer pads.

Spread thermal compound on the GPU thinly and evenly using the included paste packet, or a piece of thick paper (such as a business card).

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 needed. Koolance heat transfer pads can have different thicknesses (0.5mm, 0.7mm, and 1.0mm).

After cutting the proper shapes for your block, peel the protective film from each pad.

Apply each thermal pad to the water block as illustrated in the provided thermal pad diagram.

Unplug the heat sink fan wire. Remove the original RAM thermal transfer material, and wipe any residual thermal material from the main GPU chipset.

Basically, any area of the video card in contact with the original heat sink will

need new heat transfer material. Place thermal pads on the corresponding areas of the Koolance water block. Additionally, the VID-NXTTN aluminum back plate will also require thermal pads.

VID-NXTTN Water Block and Back Plate Thermal Pad Locations

Multiple types of heat transfer pads are included with some Koolance blocks. You might not require both (check the pad diagram). This is done because card manufactures change the component height tolerance from time to time. After completing video block assembly, it’ s recommended to remove the block temporarily to check thermal paste and pad impressions for good component contact:

• If the GPU area paste is not evenly disrupted, thinner thermal pads may be needed in corresponding areas to improve GPU contact.

• If thermal pads have no chip indentations but the GPU paste looks good, thicker thermal pads may be needed to improve contact in those areas.

Place the aluminum back plate on the reverse side of the video card. Using the Koolance-supplied screws, tighten each location on the Koolance back plate to assemble the video card and water block. Plastic insulating washers can optionally be used on the back plate to help prevent scratching.

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.

Place the Koolance block onto the video card so the mounting screws will align.
