1. Preparing your graphics card
a. Remove the existing heat sink
b. Carefully clean the GPU (graphics processing unit)
c. Install the block gasket. W e recommend coating the surroundings of the graphics processor with dielectric grease, as shown in
the example below. This will prevent condensation to f orm on the surf ace of the circuit board.

d. Lightly coat the GPU with the provided thermal compound. 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-T™ cooler
a. The MCW40-T™ retention mechanism uses the f our 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-T™ can 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 gr aphics card comes equipped with memor y 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.
d. Install the back gasket c entered between the 4 retention screws/springs assemblies.
e. Connect the thermo-electric element to your power supply. Minimum required amperage is 8 amps at 12 volts. A good quality
400 Watts power supply is rec ommended.
3. Connecting the MCW40T™ t o the r est of the cooling circuit
a. Terminate each end of the tubing with 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. Insert each tube in the inlet and outlet of the MCW40™ . It is essential to ens ure 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 MCW40™ in a liquid c ooling circuit:
Pump
Outlet

Outlet
Radiator
e. Re-install the graphics c ard in the AGP slot, and proceed with filling and bleeding the cooling circuit. A mix of 75% pur ified
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.
