3. Cutting Tube lengths, and installing the tubing
In order to better estimate the appropriate tube lengths between each
device, it is necessary to temporarily install all the cooling components first.
The water-blocks are shipped with pre-installed tubing on the inlet and
outlet (2 feet each). Your kit also comes with 5 feet of ½” OD tubing which
is normally sufficient to accommodate most configurations, including dual
processors. Also included, are two 2 ½” feet pre-cut pieces which will be
used for filling and bleeding the system, and 1 ½ foot of 5/8” OD tubing
which will be used to connect the pump.
You should start by wrapping the Coolsleeves coil around the 7-foot piece
of tube. The coil measures 40” at rest. You can stretch it to approximately
6 feet once it has been wrapped around the tube. Pulling on each extremity
of the tube itself will “even out” the spacing between the coils.
With one end of the tube connected to a startup component such as the
pump for example, roughly estimate the length you will need to the next
component. If you are going to a component with a quick-connect fitting,
make sure to allocate approximately ¾” of tube to go into the fitting. Then
cut the tube and coil with a pair of scissors, 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 the fitting.
Work your way through the entire circuit in the same fashion, until you are
satisfied with the tube routing.
4. Coolers final installation
Dismount the coolers from the motherboard and VGA adapter, remove the
protective paper, and connect the tubes to each cooler as follows:
Rollback the coil by a couple of inches, as this will give you a better
grip onto the naked tube for the next step.
Insert the tube into the quick-connect 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.
Work your way to the next components in the same fashion to daisy
chain all the components together.
Proceed to the final installation of the coolers with thermal
compound, following the instructions provided in the
individual coolers installation guides (reprinted in
Appendix)
Once everything is in place, 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).
5. Pump installation & connection to the rest of the circuit
Please refer to the separate installation guide for specific
information regarding the pump (reprinted in Appendix). Preferable
position is at the bottom of the chassis. However, the pump can
operate in any position. For optimum safety, the pump can be
bolted to the chassis. TIP! Do not peel-off the protective sticker until
you are satisfied with the position of the pump, as subsequent
removal is destructive to the foam gasket.
The pump’s inlet and outlet are ½” in outside diameter. A
1 foot
supply of ½” ID tubing is provided with your kit together with two
reducers to make the transition to the rest of the circuit. TIP! Use
approximately 1ft length at the inlet, and a few inches at the outlet,
as shown in figure 5.

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.
TIP!
For this temporary installation, interposing a piece of paper
between the cooler and the processor will protect both the cooler
and the processor surfaces.
