1. Preparing the motherboard
Remove the stock heatsink retention frame (the black plastic frame
that clips down to your motherboard). This will reveal the four
mounting holes used to install the MCW5000-PT
 retention
standoffs.
Install a standoff in each one of the holes. As the diameter of the
mounting holes is much larger than the diameter of the standoff stem,
be careful to keep the standoff approximately centered in the MB
holes. Secure standoffs with hex locknuts, and a fiber washer on
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 TIGHT, WITHOUT EXCESSIVE
TORQUE.
2. 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.
a. Motherboard preparation
• 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
http://www.swiftnets.com/store/category.asp?CatID=11 - Equivalent products can also be used, but sprays are
recommended for their ease of use.
Figure 3
Figure 4
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), and remove
the masking tape. Then let the board dry completely per manufacturer
specs.
