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

VID-385/387 Installation Guide v 1.0
The VID-385 is designed for ATI Radeon HD 3850 cards. The VID-387 is designed
for ATI Radeon HD 3870 cards. The video card should be removed from the
chassis in order to install this cooling device.
Most cards using the VID-385 and VID-387 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.
The rear GPU retention bracket and backplate screws should be
removed fi rst (on the video card’s bottom side). There should be
about 9 of these on the video card. There may also be heat sink mounting screws
on the side of the L-bracket.
HD 3870 Disassembly Screws
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 heat sinks and thermal
material, and wipe any residual thermal material from the main GPU chipset.

Insulating Washer
Thermal paste is only required on the main GPU. The
3
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 is not required
on the surrounding metal support frame.
Apply a small amount of thermal paste to the junction between
the voltage regulator block and the main VID cooling block.
Attach the voltage regulator block to the main VID block using the included 3
large screws.

Heat transfer pads have plastic fi lm on one or both sides that
must be removed before application.
Place the 4 heat transfer pads on each
additional area cooled by the Koolance liquid
block. This includes 3 rows of memory, and
one VReg area.
Place the Koolance block over the video
card.
Tighten each screw on the reverse side of the card. If the original mounting screws
do not fi t, use the Koolance-supplied screws and plastic insulating washers,
Koolance VID water blocks 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 Koolance VID-series
coolers which can be placed
opposite the desired nozzle
locations.
