1. Preparing your graphics card
a. Remove the existing heat sink
b. Carefully clean the GPU (graphics processing unit)
c. Lightly c oat the GPU with the provided thermal c ompound. Only a paper-thin coat is necessary. It should be applied using
preferably a razor blade, or a credit card, held between thumb and index at a 45-degree angle.
2. Installing the MCW40™ cooler
a. The MCW 40™ retention mechanism uses the four mounting holes standard specified in GeForce™ GPU's as shown in the
schematic above. It c an als o be installed with other graphics processors by using permanent bonding agents, such as
thermally conductive epoxies. W e recommend Arctic Silver™ or Arctic Alumina™ epoxy.
b. The MCW 40™ c an be oriented in any position, as needed to clear components on the board, except for one: the inlet and
outlet should not be oriented towards the motherboard as the block would otherwise interfere with installation of the graphics
card.

c. If the graphics c ard comes equipped with memory heat sinks, it may become necessary to remove or replace the heat sinks
with low profile after-market parts. To re-install thes e heat sinks, Arctic Alumina™ epoxy is recommended for optimum
performance instead of thermally conductive tape.
3. Connecting the MCW40™ to the rest of the cooling circuit
a. Terminate each end of the tubing wit h the provided plastic tube inserts. These inserts are mandatory with vinyl tubing, such as
provided in your package, but are not necessary with harder types of tubing such as polyethylene.
b. Ins ert each tube in the inlet and outlet of the MCW 40™ . It is essential to ensure that the tube is pushed all the way inside the
fitting: with transparent vinyl tubing, a good way to verify correct installation is to make sure that the plastic tube insert is no
longer visible outside of the block.

c. Note concerning removal of the tubing: Push in collet squarely against face of fitting. With the collet held in this position, the
tube can be removed with a firm pull. Do not attempt to pull the tube out without pushing s quarely against the collet. This may
result in damaging the fitting. Further details f or using quick-connect fittings are als o available here:

d. Recommended insertion of the MCW 40™ in a liquid cooling circuit:
Pump

Radiator
e. Re-install the graphics card in the AGP slot, and proceed with filling and bleeding the c ooling circuit. A mix of 75% purif ied
water and 25% antifreeze is recommended

4. Final inspection
Once the installation is completed, it is always a good idea to test the circuit for leaks, prior to powering up the computer.
