Note: While positioning screws, keep heatsink level by holding it in place with one hand. Reminder: Hold heatsink by its sides. Never press down on the top of the heatsink. 6 To secure heatsink to processor, again tighten screws (8 lb.- in. or 0.904 Nm torque) in order shown until they are “finger tight.” Then turn each screw (in order shown) 1/4 turn more.
Mac Pro (Early 2009) Take Apart — Processor Heatsink, Quad Core 162 2010-09-27 First Steps Open computer, lay it down with access side facing up, and remove: • Processor tray Tools • ESD wrist strap • Long-handled, magnetized 3 mm flathead hex driver Processor Heatsink, Quad Core Note: This procedure applies to the Mac Pro (Early 2009) quad-core processor configuration. For the 8-core processor configuration, see “Processor Heatsinks, 8 Core.” Important: Mac Pro (Early 2009) quad-core processors require thermal grease for proper operation.
