Koolance GPU-180 User manual

The video card or motherboard should be removed from the chassis in order
to install the chipset cooler. The mounting screws are inserted from the back
side of the board.
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.
Koolance does not recommend using a liquid cooler on video cards
or motherboards that lack standard mounting holes, or have heat
sinks that are attached with only an adhesive (rather than screws or
bolts).
Beneath the board, the plastic tabs must be
squeezed together with needle-nose pliers in
order to free the original heat sink. (Some
tabs have locking center pins which must
first be removed from the top.)
Once loosened, remove the original
heat sink. Apply a thin layer of thermal
interface compound onto the chipset if
necessary.
!
Remove the protective tape from the bottom
of the chipset cooler.
To help keep them secure, place rubber
washers over the metal screws from above
the board.
Through the original heat sink
mounting holes, insert both metal
mounting screws from the back of
the board. Make sure the plastic
insulating washers are placed on
each screw.
For ATI Radeon video chipsets, place the
included adhesive foam pad around the chipset
core for a flatter mounting surface.
GPU-180 Installation Guide v 1.1

Place the liquid cooler onto the video or
motherboard chipset and align the mounting
bracket. The bracket is highly-adjustable for
proper alignment.
(NOTE: For some models of GPU-180 coolers,
you may need to re-adjust your nozzles to
provide more clearance for the bracket.)
Use the metal attachment nuts to fasten the
mounting bracket to the chipset. Hand-
tighten all video card components.
It is OK for the chipset cooler to sit
diagonally on the video card or motherboard.
Cooling efficiency will be the same.
Heat sinks are included for attachment to video
memory chips for additional cooling. Depending
on the video card, you may not require all 8 heat
sinks.
Two sets of bracket tabs are included with
the chipset cooler. Use whichever tabs
best align the cooler over the mounting
screws.

Mounting on a P-4 Northbridge Chipset
Many motherboards for P-4 chips feature heat sinks which are “hooked”
rather than bolted to the Northbridge chipset. Use the four attachment springs
included with the GPU-180 cooler to secure the bracket to this type of chipset.
