I. Preparing the motherboard

You must uninstall your MB prior to installing the MCW462-U water-block.

• Install standoffs in MB

Determine which standoff washers to use, depending on your MB mounting holes:

• Large holes .230”(5.8mm) diameter : use .220x.046 Nylon spacers. The washers fit inside the MB hole.
o Small grounded holes .150”(3.8mm) diameter: you can recognize grounding by a silver ring around the holes; no washers

needed nor necessary.

o Small holes, NOT grounded (bare circuit board): you must use black fiber washers, or damage to the MB may occur.

• Re-install the MB inside the case.

II. Water-block installation

• The case should be laying flat on a table.

• Insert the processor into the socket, and lightly coat the processor core with high quality 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 45­degree angle. It is critical to ascertain that the entire core is covered with a uniform coat of thermal compound. Thermal performance
will dramatically decrease if any portion of the core is not covered by thermal compound. We recommend Arctic Silver or similar
high-end compound for superior thermal conductivity.

• Insert the tubing into your MCW462-U water-block prior to installing it onto the CPU. The reason is that inserting the tubes

into the fittings requires some strength, and it is preferable not to do this while the block is sitting on the CPU. If you are going to use
soft vinyl tubing (transparent tubing), it is IMPERATIVE to use the two plastic inserts provided with your kit.

• Prepare 4 assemblies composed of a 1 ½” screw, 1 nylon spacer, and 1 spring as shown in Figure 2. Drop each assembly into the

MCW462-U mounting holes.

Install standoff in each one of the
four holes surrounding the socket.
Keep the standoff & washer
centered over the MB holes, and
secure with nylon hex nuts on
backside of the MB. If you are
going to assemble/disassemble the
heat sink frequently, we
recommend finishing the installation
by putting a drop of “Crazy Glue “ at
the junction between standoff & MB,
and between nylon hex nut & MB.
This will lock the standoff onto the
MB, and further prevent it from
spinning lose during frequent
assembly and disassembly
operations.

Information subject to change without notice

• Orientation of the block is important for bleeding

purposes. Please look-up the critical bleeding instructions

paragraph below prior to installing the block on the CPU.

• Install the MCW462-U block on the CPU. The copper base

of the MCW462-U features a large step for clearance with the
socket cam box. Make sure to respect this orientation. Keep
the heat sink mounting holes lined up with the standoffs.
Avoid twisting the block to prevent smearing the thermal
compound.

• Gradually tighten the screws in a crisscross pattern until

you feel that they reach the bottom of the standoff. A “finger­tight” lock is sufficient. Over tightening may result in stripping
the nylon hex nut. Conversely, adjustments such as
tightening the screws only partially are strictly prohibited
Such attempts will result in improper contact between the
CPU core and the heat sink, and result in CPU overheating.

CRITICAL BLEEDING INSTRUCTIONS:

The following applies mostly to dual processor installations.
Depending on the orientation of the socket, it is critical to
observe the position in which your water-block is oriented for
bleeding purposes. Assuming that the computer is standing
up, and that the water-block is facing you as shown in Fig.1A
and Fig 2A. below, Fig. 1A shows the two positions in which
the MCW462-U will bleed correctly, and Fig. 2A shows the
two positions in which the MCW462-U will not bleed.

Two solutions are available to bleed the water-block correctly:

1. Bleed the water-block prior to installing on the CPU. Simply rotate the block in the position shown in Fig. 1A.

2. If you prefer to install the block first, then bleeding should be done with the computer laying down flat so that the Swiftech
logo is facing downwards, as shown in Fig. 3A

III. Temperature troubleshooting

IMPORTANT WARNING: AMD compatible motherboards measure the CPU temperature via a thermal probe located inside the socket. The

probe only measures the air temperature underneath the CPU. Motherboard manufacturers use mathematic formulas to extrapolate the actual
CPU temperature. Such formulas use correction factors to account for airflow around the socket generated by a conventional heatsink fan
cooler. In a liquid cooling environment, there is no airflow at all around the socket, since there is no fan attached to the water-block. This
leads to erroneous readings from the motherboard thermal probe, which reports much higher CPU temperatures than actual. Troubleshooting
