Cooler Orientation
In relation to the cooler’s centrally located fan, air flows from the “thinner”(front)
heatsink to the “thicker”(rear) heatsink. As shown in the diagram below, it is
recommended that the cooler be installed so that air flows from the cooler toward
the enclosure’s rear exhaust fan to be released.

④
Cooler Installation
Align the center of the cooler with the
center of the CPU, and fix by tightening
the bolts on the Clip onto the Clip
Support.
The Clip must be installed lying flat, without leaning at a slant in any direction.
The PWM fan’s operation will vary depending on the motherboard’s BIOS
settings. After installation, the PWM Control Mode must be activated in the BIOS.
For details regarding PWM Control Mode, please refer to the motherboard’s manual.
⑤
Power Connection
Please connect the cooler’s 4-pin connector to the motherboard’s CPU Fan header.
For easier installation, stabilize the
Clip by initially tightening each bolt
by one turn or just enough to latch
onto the Clip Support’s threading.
