Installing Processor Heatsinks
Depending on your configuration, the heatsink for each processor’s S.E.C. cartridge
might notbe attachedto thecartridge. Inthis case,you must attach one heatsink to each
S.E.C. cartridge. Use Figure 2-8 and the following steps:
1. Remove the heatsink from its protective cover.
2. Pull the tab on the bottom of the heatsink to remove the plastic film and expose the
square of adhesive thermal grease that will help attach the heatsink to the S.E.C.
cartridge. This square is offset, so that more of it is on one side of the center screw
hole than on the other side. This offset side (see Figure 2-8) must point toward the
connector end of the S.E.C. cartridge.
3. Orient the heatsink on the silver metal side of the processor so that:
■ The side with more of the grease square points toward the S.E.C. cartridge
connector
■ The side with less of the grease square points toward the processor tabs
■ All five screw holes align correctly with the holes in the S.E.C. cartridge
4. Because of the adhesive grease on the heatsink, be careful to orient the heatsink
properly before placing it against the S.E.C. cartridge.
5. Attach the heatsinkto the S.E.C. cartridgewith five 6-32x 1/4screws, and tighten to
8-10 inch-pounds.
