This product is intended for expert users. Please consult with a qualified technician for installation. Improper installation may result in damage to
your components. Swiftech assumes no liability whatsoever, expressed or implied, for the use of these products, nor their installation. The
following instructions are subject to change without notice. Please visit our web site at
for updates.
1.
Before you install the MCW20-A™ water-block:
a.
Prepare two pieces of tubing
of sufficient length to connect
to the rest of your circuit. The cuts must be square as shown in
figure 1 or leaks may occur:
b
. Install the provided plastic tube inserts
at each end of the tubes,
as shown in figure 2: these inserts are absolutely
imperative
when
using any kind of
soft
tubing, such as vynil, ClearFlex, Taigon, etc...

c
. Spread a little bit of grease
or liquid soap
around the tubing. It helps pushing the tubes in,
particularly with Clearflex
tubing, which
features a very “sticky” surface.
d.
Fully insert both tubes into the fittings
. The tip of the plastic tube inserts should
be flush with the inlet and outlet openings, as shown in figure 4 above. Inserting the
tubes requires a firm push, accompanied by a twisting motion.
2.
Preparing your Motherboard
Remove the motherboard from the chassis
Remove the existing heat sink
Carefully clean the microprocessor, using alcohol
3.
Installing the MCW20-A™ water-block with AMD
platform motherboards
Install the provided screws through the motherboard, using a black fiber washer on both sides of the motherboard, and tighten the
nuts.
Install the motherboard in the chassis
Lightly coat the microprocessor 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
.
TIP! It is preferable to have the tubing inserted into the water-block BEFORE you install the block onto the motherboard.
This is because pushing the tubes into the block while it is already installed could exert undue pressure onto the
microprocessor.
Slide down the MCW20-A over the retention screws, then install the nylon tension limiters (flange facing down), the springs, and
tighten the assembly with the knurled knobs. Over tightening of the assembly is prevented by the tension limiter. Users should be
cautious nonetheless, as nylon can be easily crushed.
