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 my void your manufac­turer’s hardware warranty. Please consult the manufacturer if unsure,

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

All heat sink assembly screws should be removed.
There should be 16 of these on the back of the
video card (including the cross brackets). There
are an additional 5 screws on the top and side
L-bracket.

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.

Gray thermal pads have plastic fi lm on both sides that must
be removed before application. White/Pink thermal pads only
have plastic fi lm on one side (white) that must be removed.
Do this after cutting the proper shapes.

Two different sets of heat transfer pads
are included, and each set has a different

thickness. The thermal pad sheet should
be cut into pieces required for your video block contact
areas. Please use the below diagram to determine the
proper sizes.

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

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.

Using the Koolance-supplied screws and plastic insulating washers, tighten each
screw on the reverse side of the card. Utilize the original video card screws for
the rear GPU “cross brackets”.

Thumb nuts are
supplied to take the
place of empty screw
hole positions on
the top of the video
card.

Connecting VID Coolers in SLI or CrossFire

When connecting multiple VID coolers in series, Koolance offers an optional direct­connect nozzle. This minimizes liquid routing while avoiding potential confl icts with
hardware in between the video cards.
