User Manual

Install two G 1/4” threaded nozzles (sold separately) into
the cooling block. Hand tighten all nozzles-- overtightening
can damage the block.
CAUTION: Be sure to attach the Koolance temperature probe to the
CPU cooler during installation. The safety features of your system may
not function properly without the correct placement of this probe, and
hardware damage can result.

Remove any protective fi lm from
the bottom of the cold plate.
Place the temperature sensor
on the edge or side of the water
block’s metal cold plate. The
sensor is required for automatic
Koolance fan control and safety
features.
Trim out a piece of metal tape and apply it to keep the
temperature probe in place. DO NOT stick metal tape or
the temperature probe where the processor comes in
contact with the cooler.
You can use a zip-tie to further secure the temperature
probe wire to the CPU water block’s tubing.
DO NOT attempt to install the temperature probe in
between the processor and cooler. Despite its thin size, it
will interfere with CPU contact or burn-out the sensor.
Apply thermal paste to the CPU directly. Spread the
paste so that it evenly covers the CPU. A piece of thick
paper (such as a business card) works well for this.
Place the CPU cooler on top of the processor. The
temperature sensor should already be installed on the
cooler.
For hinging posts, place the mounting bracket over the CPU cooler. On the end
of each post, insert a metal pivot ball. Finally, use 4 springs and thumb nuts to
secure the water block against the processor. DO NOT OVER TIGHTEN! Keep
the water block approximately centered over the processor when tightening.

For threaded posts,
place the mounting
bracket over the CPU
cooler. Use either 2 or
4 springs and thumb
nuts (depending on
socket type) to secure
the cooler against the
processor. DO NOT
OVER TIGHTEN!

Some processors, like AMD socket
754/939/940, require removal of the
motherboard’s black plastic retention frame in order to install
the Koolance water block.
If present, remove this retention frame by unscrewing its
screws, or if plastic tabs are used, pulling out these locking
tabs.
Your Koolance water block may have threaded or hinging
posts. Installation varies with both types.
Threaded Posts
Hinging Posts
(Refer to bracket diagrams on the following page for
specifi c CPU post positioning.)
Threaded posts are screwed directly
into the CPU block’s rear bracket. Pliers
or a small wrench may be required to fully tighten
the posts.
Hinging posts are simply
inserted through the rear
bracket. However, the
beveled edge of the post
holes must correspond
with the head of the
hinging post. Each post
head should sit fl ush with
the rear bracket.
Hole Bevel
Place the required rubber
insulation pad over the bracket
posts.
For Intel socket LGA 1366, use
the pad with the rectangular
center hole to accommodate the
motherboard’s default plate.
1366 Pad
Use these Koolance CPU bracket diagrams to determine which holes your
mounting posts must be inserted into.

NOTES ON DISASSEMBLY: Both the CPU-345 and CPU-350
can be opened (for cleaning, etc.) by carefully unscrewing
the top cover from the cold plate. This is easier to do with
nozzles installed. Be sure all internal rubber O-ring gaskets
are properly positioned during reassembly.
During reassembly, the CPU-350’s internal constriction plate
should be positioned so that its small corner alignment hole
matches with the cold plate’s corner alignment hole.
