    First Steps
    Open computer, lay it 
    down with access side 
    facing up, and remove:
    • Processor tray
    • Processor heatsink, 
    quad core
    Tools

    • Flatblade screwdriver
    Processor, Quad Core
    Note: This procedure applies to the Mac Pro (Early 2009) quad-core processor configuration. For 
    8-core processor configurations, see “Processor, 8 Core.”
    Important: Mac Pro (Early 2009) quad-core processors require thermal grease for proper 
    operation. Every time you remove a processor heatsink, you must replace the thermal grease on 
    the processor below it. New grease and alcohol wipes for cleaning off the previous grease are 
    included with replacement heatsinks, processors, and processor boards.

    Removal
    Note: You can identify the 
    processor by the speed 
    etched on the processor 
    can. You must clean off 
    the thermal grease from 
    installed processors to see 
    the speed.
    1 Release latch on 
    metal processor 
    holder.
    Note: You may use a 
    flatblade screwdriver to 
    help release latch.
    2 Rotate top of holder 
    to open position.

    up out of holder.
    Important: Do not touch 
    components on processor 
    top or bottom. Hold 
    processor only by the

    Reassembly
    Important: Do steps 1–3 
    with processor REMOVED 
    from processor board. 
    Every time you remove 
    a processor, even for a 
    few seconds, cover the 
    processor socket with 
    a connector cap. Spare 
    caps are packed with 
    replacement parts.
    1 Using alcohol pad 
    included with 
    replacement part, 
    clean off thermal 
    grease from 
    underside of heatsink 
    and top of processor.
    Note: You do not 
    need to clean a 
    new replacement 
    processor with 
    alcohol. Instead, just 
    remove the protective 
    cap covering the 
    processor’s connector.

    replacement part, 
    apply narrow bead of 
    grease to processor 
    chip (raised square on 
    top of processor). 
    Apply in pattern 
    illustrated, using 
    approximately 0.2 cc.
    Warning: Do not 
    apply more grease 
    than recommended.
    Grease must not 
    overflow into 
    processor connector.
