1.
Preparing the motherboard
Remove the stock heatsink retention mechanism to reveal the four-
motherboard mounting holes.
Install a standoff in each one of the holes. As the diameter of the
mounting holes is usually larger than the diameter of the standoff
stem, be careful to keep the standoff approximately centered in the
MB holes. Secure the standoffs with the provided hex locknuts, and a
fiber washer on the backside of the MB as shown on fig. 1, using the
tools described fig. 2
Figure 2
Use a ¼” socket tool to drive the standoff, and a small pair of pliers
to prevent the locknut from spinning. Torque value should not to
exceed 16 in. lbs. In other words JUST FIRM AND TIGHT, BUT
WITHOUT EXCESSIVE TORQUE.

Condensation control measures
The following instructions are crucial to long lasting & reliable operations. Do not skip these steps, and do not take shortcuts. Permanent damage to
your components is likely to occur otherwise.

Conformal coating application: This step will positively ensure that any micro condensation occurring on small surface
mount components will not corrode or short-circuit the motherboard.
Procure a spray can of silicone conformal coating. We use M.G. chemicals Acrylic Conformal Coating, part # 419B-340g.
The product can be purchased at our online store here

products can also be used, but sprays are recommended for their ease of use.

Figure 4 - Front of the motherboard
Spray the back of the motherboard, concentrating on the area
immediately behind the CPU. Also spray all the way down, in a
vertical path directly under the CPU area. Allow time to dry, per
manufacturer specs.
Use masking tape to protect the CPU socket, and any connector sockets
in the immediate vicinity of the processor. A double layer of tape is
recommended for all sockets, as the spray may soak a single layer of
tape and contaminate the contacts.
Spray the area immediately surrounding the socket. It is not
recommended to spray further than the area circled in the above picture.
Allow the coating to be “dry to the touch” (20 minutes approximately),
