VID-428 Installation Guide v 1.0

NOTE: The video card should be removed from the chassis in order to install this
cooling device.

CAUTION: Removal of the original heat sink my void your manufac­turer’s hardware warranty. Please consult the manufacturer if unsure,

!

and keep all original parts in case of a return/RMA.

Most cards using the VID-series blocks are disassembled the same way, although
heat sink assemblies of any given model can vary.

The spring-screws on the bottom
side should be removed fi rst. There
should be about 10-12 of these on
the video card, including mounting
screws on the side of the L-bracket.

Example: GTX 280 Disassembly Screws

Removing the rear
outer casing will reveal
two more screws which
must be removed.

This will free the front
heat sink and casing
for removal.

The heat sink and fan can now be carefully removed. Original thermal paste
may present additional resistance while removing the heat sink. Unplug the heat
sink fan wire. Remove the original RAM thermal transfer material, and wipe any
residual thermal material from the main GPU chipset.

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).

Carefully pry apart the rear outer casing starting at the L-bracket. The plastic
assembly tab hooks can be gently depressed with a fl at screw driver to unlock
this area. Exercise caution-- these tabs can be easily broken.

After cutting out each piece, place the heat transfer
pads on each additional area cooled by the Koolance
liquid block and its rear heat sink plate. This includes 16
memory chips, 7 power/VReg chips, and 1 PCI-Express
controller chip.

Thermal Paste Area

Two different sets of heat transfer pads are included. Each
set has a different thickness, and one should be chosen that
offers best contact with your video card.

The thermal pad sheet should be cut into
pieces required for your video block contact areas. A paper
stencil with the proper shapes and sizes is included for
reference.

Thermal pads may have plastic fi lm on one or both sides
that must be removed before application.

Two G1/4 “caps” are included
with the VID coolers which can
be placed opposite the desired
nozzle locations.

Koolance VID coolers include redundant
G 1/4” threading on both sides. This
means the input/output nozzles can be
placed on either side of the cooler.

Connecting VID Coolers in SLI

When connecting VID coolers in series (such as in SLI), Koolance offers an optional
direct-connect nozzle. This minimizes liquid routing while avoiding potential confl icts
with hardware in between the video cards.

VID-428 Thermal Pad Areas (Rear Heat Sink Plate)

Place the Koolance block over the video
card, and position the rear heat sink plate
beneath it.

Using the Koolance-supplied screws, tighten
each screw on the reverse side of the card
through the rear heat sink plate.
