Swiftech MCW50 T - Manual (Page 2)

IMPORTANT PRE-INSTALLATION NOTE:
The MCW50-T™ ships pre-assembled for installation through the two diagonal holes located on either sides of the graphics processor as
shown in figure 2. This provides compatibility with all ATI
 Radeon 9000 to 9700 families of products, and some nvidia products.
For use with nVidia
 products please read the following:
If the spacing between the two diagonal mounting holes featured on your graphics card match the spacing between the two
mounting screws of the MCW50-T™, there is nothing to do. Simply follow ATI
 installation.
If the spacing if different, then you must use the 4 retaining spring assemblies as shown in figure 1. You will need first to remove
the two 4-40 x 1 ¼” Phillips screws holding the stainless steel frame to the MCW50-T™ body, and replace them with the two 4-40
x ¼” socket screws provided with your nVidia
 hardware kit.
5. Preparing your graphics card
Remove the existing heat sink
Carefully clean the GPU (graphics processing unit) with alcohol, or preferably xylene.
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.
Lightly coat the components surrounding the core with dielectric grease as shown in either figure 3 or 4 depending on your
application. Be careful not to spill or spread dielectric grease over the thermal compound.
You can also use silicone conformal coating instead of dielectric grease. The product comes in convenient sprays, and cures in
less than an hour. Before you apply the spray, make absolutely sure that you protect the GPU core, and the gold AGP contacts,
using masking tape. Then, simply spray around the area surrounding the GPU, and repeat the operation on the backside of the
card, in the area immediately behind the GPU. Most types of masking tape are permeable; therefore, it is a good idea to remove the
masking tape immediately after you applied the conformal coating, and wipe off the AGP gold contacts and the GPU with Xylene.
Where to buy conformal coating? Google search keyword: conformal coating. In house, we use the product made by M.G.
chemicals.

6. Installing the MCW50-T™
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-T™ Inlet and outlet. It is
absolutely imperative to use the provided tube
inserts with clear vinyl (soft) tubing, as shown
below:
Figure 5 Figure 6
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 in figure 6 above.
Inserting the tubes requires a firm push, accompanied by a twisting motion, and a little
bit of grease around the tubing really helps ☺
Install your block onto the graphics card, as shown in Figure 1 or Figure 2 (p.1) according to on 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.
Stick the provided back-of-board gasket directly behind the graphics processor. It is necessary to slightly trim the corners of the gasket
when using nVidia
 4-spring retention assembly.
