Koolance VID-487 - Manual

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 manufac-
turer’s hardware warranty. Please consult the manufacturer if unsure,
and keep all original parts in case of a return/RMA.

VID-485,487 Installation Guide v 1.0
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 12-14 of these
on the video card. There may also be smaller
mounting screws on the side of the L-bracket.

Connecting VID Coolers in SLI or CrossFire
When connecting multiple VID coolers in series, Koolance offers an optional direct-
connect nozzle. This minimizes liquid routing while avoiding potential confl icts with
hardware in between the video cards.

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

Place the Koolance block over the video card
and tighten each spring-screw on the reverse
side of the card.
Using the Koolance-supplied screws and plastic insulating washers, tighten each
screw on the reverse side of the card.
Koolance VID coolers include redundant G1/4 threading on both sides. This means
the input/output nozzles can be placed on either side of the cooler.
Two G1/4 “caps” are included
with the VID coolers which can
be placed opposite the desired
nozzle locations.
Place heat transfer pads on each additional area cooled by
the Koolance liquid block. This includes 2 rows of memory,
and 1-2 power/VReg area.

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 thinly and evenly
using the included paste packet, or a piece of thick paper
(such as a business card). Thermal paste should not be
placed on the surrounding metal support frame or small
surface soldered components.
