5. Cutting the tubing, & connecting components
Now that your mock-up installation is in place, it is time to cut segments of
tubing and connect the devices together.
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 sufficient 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.

Figure 5
Gather Coolsleeves ™ towards the center of the tubing, then pull on the ends of
the tubing. This will allow Coolsleeves ™ to expand to its 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 a component featuring a
quick-connect fitting, 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.
6. Preparing the coolant
Your kit comes with a 2 Oz (60ml) bottle of Swiftech’s specially
formulated HydrX
 concentrated coolant. The product should be
mixed with distilled or demineralized water only. Simply empty
the concentrated coolant into a 33 fl oz (1 liter) plastic bottle, and
complete filling with your distilled water. Your coolant is ready.
7. Filling up the circuit
Please refer to the MCRES-525 installation guide in appendix for
specifics on how to fill-up the system. In this paragraph, we will
discuss safety measures.
It is good practice to pre-test that your system is liquid-tight away
from sensitive electronic components. Two strategies can be
employed:
Dismount all the components that you installed in
the mock-up, and fill-up your system outside of
the case, or
Remove motherboard, VGA adapter, hard drives
and CD Rom (if any), from the chassis, which is
our preferred solution.
In either case, you will need to start-up your pump in order to
completely fill-up the system. Since your MCP650 is a 12Volts
pump feeding off the computer power-supply, you must be able
to start the PSU without it being connected to the motherboard.
While the Internet is full of references on how to short-out pin 14
and 15 of the ATX connector to start up the PSU independently,
we really do not recommend this method. The safe and proper
method to start-up the PSU independently is to use a power-
supply tester. A wide variety of these common devices is
available on the Internet (google key word: “PSU tester”), and
among Swiftech resellers (
www.frozencpu.com ,
www.Directron.com , www.newegg,.com etc..)
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.
