2. Mount the Heatsink: Place the SEC cartridge face down on a flat surface and lay
the heat sink flush on the back (metal side) of the SEC cartridge. Check the orien-
tation of the heatsink against the pictures. The thicker fin must be orientated
toward the bottom. The top clamp is wider than the bottom clamp so only this
orientation will fit. With a screw driver, push the clamps one at a time into the
SEC cartridge. Be sure that the heatsink is firmly pressed against the SEC car-
tridge. When correctly installed, no light must be showing through between the
thermal pad of the heatsink and the SEC cartridge.
WARNING! If the heatsink is not mounted tightly against the SEC cartridge,
the CPU will overheat. You may install an auxiliary fan to provide adequate
circulation across the processor’s passive heatsink.
