VID-NX590 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.
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.
