1. Preparing your graphics card
a. Remove the existing heat sink
b. Carefully clean the GPU (graphics processing unit)
c. 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. Before installing the block onto the graphics card cut two pieces of tubing of sufficient length to connect to the rest of your circuit, and
install them into the MCW50™ Inlet and outlet. It is absolutely imperative to use the provided tube inserts with clear vinyl (soft) tubing,
as shown below:
Shown here with an MCW50-T™ version
Make sure that the tubes are fully inserted into the fitting. The tip of the plastic tube inserts
should be flush with the inlet and outlet openings, as shown above. Inserting the tubes
requires a firm push, accompanied by a twisting motion, and a little bit of grease around
the tubing really helps ☺

The MCW50™ retention mechanism can either use the two diagonal holes featured in many graphics cards
families of products. It can also be installed with other graphics processors by using permanent bonding agents, such as thermally
conductive epoxies. We recommend Arctic Silver™ or Arctic Alumina™ epoxy.
Install your block onto the graphics card, as shown in Figure 1 or Figure 2 (p.1) according to your application. A “finger –tight” lock is
sufficient when tightening the spring retention assemblies. Over-tightening will squish the nylon screw spacer body, and result in uneven
pressure over the GPU.
4. Recommended integration of the MCW50™ in an existing liquid cooling circuit:
Radiator

such as ATI Radeon™ 9000 to 9700 families, or the four mounting holes found in NVidia GeForce™

5. Re-install the graphics card in the AGP slot, and proceed with filling and bleeding the cooling circuit.
6. Type of Coolant:
a. For best performance, use 95% distilled water, and 5% Swiftech brand “HydrX” corrosion inhibitor (available here:
http://www.swiftnets.com/store/category.asp?CatID=2
b. In ALL cases, you MUST use Distilled water AND a corrosion inhibitor with the MCW5002 water-block. Regular automotive
anti-freeze is acceptable. Automotive manufacturers recommend that not less than 25% is used.
c. NEVER use tap water, even for a short-term test.
, under the “accessories” section).
d. Not following paragraphs b and c above constitutes misuse (*) of the product, and will void your warranty.
7. 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.
Troubleshooting help is available on our web site at www.swiftnets.com
, or by calling customer support at 562-595-8009.
Final 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 safely pulled out. Do not attempt to pull the tube out without pushing squarely against the collet. This may result in damaging the fitting. Further
details for using quick-connect fittings are also available here: http://www.johnguest.com/install_6.shtm#disconnect
