  41. Replacing/Upgrading Mac Pro Processors (Early 2008), Replacement Note: 3.2 GHz Processors Heatsink: stap 41, afbeelding 1 van 1
    • The Mac Pro (Early 2008 Dual 3.2 GHz) computer uses a special coating on the processor heatsink and processor to manage the temperature in the computer. The silver-colored coating comes applied to the underside of the heatsink and the top of the processor.

    • Use the following guidelines when handling the processor heatsink and/or processor:

    • Wear disposable nitrile or latex gloves

    • Avoid touching the silver-colored coating on the underside of the heatsink and the top of the processor.

    • Always make a visual inspection of new or existing heatsinks and processors before installing them in the computer.

    • When removing or replacing the heatsink and/or processor, do not allow the heatsink to be separated from the processor for more than 30 minutes. The special coating on the heatsink and processor degrades with exposure to air; more than 30 minutes exposure could result in damage to the computer and a repeat, multi-part repair.

  42. Replacing/Upgrading Mac Pro Processors (Early 2008), Replacement Note: 3.2 GHz Processors Heatsink 2: stap 42, afbeelding 1 van 1
    • Before installing a new or existing heatsink, check that the gasket that surrounds the silver colored coating on the underside of the heatsink is in good condition, as shown in the graphic. Replace the gasket if it shows obvious damage, such as cracks, folds, and broken-off surfaces, or if it is dislocated from the heatsink.

    • The gasket is available through GSX as part of the Mac Pro Grease Kit, part number 076-1258.

    • Rotate the top of the holder to the open position.

    • Lift the processor out of the holder.

    • Important: When removing or installing a processor, always hold the processor by the edges. Be extremely careful not to touch the gold pins on the bottom of the processor, as this type of connector is very sensitive to contamination. Also be careful not to touch the gold pins in the processor socket on the logic board.

    • You can identify the processor by the speed etched on the processor. You must clean off the thermal grease from installed processors to see the speed.

  45. Replacing/Upgrading Mac Pro Processors (Early 2008): stap 45, afbeelding 1 van 1
    • Replacement Note: Before installing a replacement processor, remove the protective cap covering the new processor’s connector.

  46. Replacing/Upgrading Mac Pro Processors (Early 2008): stap 46, afbeelding 1 van 1
    • Replacement Note: When installing the processor on the logic board, align the processor notch with the tab on the processor holder, as illustrated. Then lower the processor straight down onto the socket.

    • Note: Unlike in earlier Power Mac G5 computers, replacing a processor in Mac Pro (Early 2008) does not require running Apple Service Diagnostic for thermal calibration.

Anyone know the specifications on the captive mounting screws for the heatsink? I'm doing an out-of-case build for a 2007 Mac Pro and need to know so that I can get the appropriate threading on my mounting board.

Hello - Antwoord

Hi there! Can you recommend which processor best fit with my machine: QUAD CORE XEON 3.0 (intel) 2.1 (mid 2008) with LION (10.7.6). I wish to run El Captain (10.11) or Sierra (10.12)..

Ricardo Magron - Antwoord

Hey, buddy, how you doing?

Has a problem with your Mac Pro 2008

After the device is turned on for a few seconds, it is stopped

Please, what's the problem?

Hi!

I just bought a 2008 3,1 MacPro with 1cpu and I was wondering if it is possible that I can add a 2nd cpu… Do I have to order another Heatsink or anything else?

Elias Wirtz - Antwoord

You will need a matching processor, a heat sink, (be careful to get the muliti copper pipes for a 3,1, not eh 1,1 or 2,1 although the older ones will work, it wont be matching), and some thermal paste.

If you are getting the 3.2 2 processor upgrade, then you will need 2 new 3.2 specific heat sinks. See the guide above for those.

Also you will need a long 3mm hex head screw driver. The Ifixit drivers barley worked.
