Prepare 4 assemblies composed of a 1 ½” screw, 2 nylon flat
washers, and 1 spring as shown in the picture to the right. Drop each
assembly in the bracket mounting holes. While gently pressing at the
center of the heat sink, start tightening the screws gradually in a
crisscross pattern until you feel that they reach the bottom of the
standoff. A “finger-tight” 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.

Fan Installation: Place the fan over the heat sink. The airflow should
be blowing down (fan label facing down). Place the fan guard over the
fan. Tighten the four 6-32 x 2” screws. The fan is equipped with two
connectors: a four pin molex connector which must be connected to the
power supply, and a 3 pin single wire connector which connects to the
MB fan sensor header.

Optional fan rheostat: a rheostat model # RH070 is sold separately,
and allows to adjust the fan speed. It connects between the fan power
connector and the power supply connector. Please consult your
distributor if you wish to purchase this item. Reducing the fan speed
reduces fan noise up to 9 dBA. It also reduces thermal performance,
and will affect overclocking performance accordingly. It is however
perfectly appropriate for non overclocked processors.

III. Final inspection

Now that the heat sink is installed, startup your computer, go into the BIOS and observe the CPU temperature. Under normal ambient
temperature conditions, the processor temperature should never exceed 55

C (130

F). If it does, shut down the computer immediately,

and review your entire installation. Troubleshooting help is available on our web site at
