3. P REPARING THE TUBING
Now that your radiator and water-block are in place, it is time to cut
segments of tubing and connect the devices together. Please look-up
paragraph 4. Section a) below to estimate the tube length that will be
necessary for the MCRES-1000 pump & reservoir assembly.
In addition to the water-block pre-installed tubing, your kit comes with an
additional 4 feet of ½” OD tubing which is normally sufficient to
accommodate most configurations, including dual processors.
Your kit also comes with a 40” length of Coolsleeves
coils which, when
extended is a sufficient length to cover 6 feet of tubing. Use of these coils is
mandatory in order to prevent kinking and flattening of the tube over time.
Start by wrapping the included Coolsleeves coil around the 4-foot
piece of tube. Leave yourself enough Coolsleeves to wrap the water-
block(s) pre-installed tubing.
Wrap the Coolsleeves coils around the tubing
Gather the Coolsleeves coils towards the center of the tubing, then pull on
the ends of the tubing. This will allow the coils to expand to their natural pitch.
Tight radii sections require that coils be close to each other (1/8” spacing coil
to coil). In straight sections, coils can be spaced up to ¼” or more, coil to coil
Then, with one end of a tube connected to a startup component such
as the water-block for example, roughly estimate the length that you
will need to the next component, and cut the tube and coil squarely
with a pair of scissors. Work your way through the entire circuit in
the same fashion, until you are satisfied with the tube routing.
Quick-connect fittings: If you are going to use a component
featuring a quick-connect fitting such as the MCW50 VGA cooler for
example, make sure to allocate approximately ¾” of tube to go into
the fitting, and install a tube insert (shown below) at the extremity of
each tube.
TIP!
Rubbing the extremity of the
tube with a little bit of liquid soap will
greatly facilitate insertion of the tube
into a quick-connect fitting.
When attaching the tube to a quick-connect fitting, rollback
the coil by a couple of inches, as this will give you a better
grip onto the naked tube to insert the tube into the fitting. The
tube will go in freely for the first ¼” and you will then feel a
resistance: this is the O-ring inside the fitting. Push through
the O-ring by twisting the tube back-and-forth for another ½”
until the tube reaches the tube-stop at the bottom of the
fitting. The tube is properly installed once the visible
extremity of the tube insert is flush with the face of the quick-
connect fitting. Then bring the coil back to the face of the
fitting.
Once everything is connected, you should then adjust the
Coolsleeves coil spacing: adjust to a wide space between
each coil (up to ¼” or more if needed) when the tube is
straight, and very close to each other in tight bends
(approximately 1/8
th of an inch or less).
With everything in place, carefully double-check each
connection. If it all looks tight and secure proceed to the next
step.

TIP!
Verify that each cooler will ‘hang’ naturally in very
close to its mounted position. If the stiffness of the tubing, or
the tight radius of the necessary bend, will not permit such,
then it may be necessary to externally support the tubing:
typically some strategically placed cable ties will facilitate this
restraint. This precaution is particularly important with AMD®
K7 class processors, but less so with Intel® Pentium® 4,
Xeon, or AMD® K8 class processors.
