Included in each step is an overview picture showing the general location and a closeup showing the actual screw. Remove the recessed Phillips screw near the power button securing the internal frame to the bottom housing. Remove the recessed Phillips screw near the sleep light securing the internal frame to the bottom housing.
This screw is the longest of the four screws securing the internal frame to the bottom case. Remove the Phillips screw near the audio ports securing the internal frame to the bottom case. Gently lift the internal frame up from the bottom housing, minding the AirPort antenna and any other cables that may get caught.
It may be necessary to pull up near the interconnect board to separate it from the logic board. Firmly grasp the power button cable connector with a pair of tweezers and lift it straight up off the logic board. Firmly grasp the sleep light cable connector with a pair of tweezers and lift it straight up off the logic board. Use the flat end of a spudger to slightly lift the logic board near the PRAM battery to separate it from the bottom housing.

It will be necessary to gently pull the sleep light shown in red away from the mini to clear the edge of the logic board. To avoid bending the fins, don't squeeze the upper portion of the heat sink perpendicular to the length of the fins. A spring loaded plastic pin at each corner of the heat sink holds it firmly against the face of the processor. The pins have barbs at one end that expand once the pin passes through the logic board. The barbs must be squeezed together to fit through the holes in the logic board.
Use extreme caution when squeezing the barbs together with pliers near the exposed face of the logic board. This step requires working with both hands and may be better accomplished with the logic board sitting in your lap. Using a plastic opening tool or similar in one hand, push down one pin holding the heat sink on the logic board. The spring under the pin will provide moderate resistance.
While holding the pin down from the heat sink side of the board, use a pair of pliers in your other hand on the underside of the board to squeeze both barbs against the plastic shaft of the pin. With both barbs squeezed together, push the pin through its hole in the logic board. Repeat this process for each of the four pins holding the heat sink on the logic board.
Use the tip of a spudger to push the heat sink thermal sensor connector out of its socket.
It may be necessary to work from alternating sides to 'walk' the connector out of its socket. To unlock the processor, use a small flathead screwdriver to rotate the processor lock degrees counter-clockwise until the indicator is near the open lock symbol. Rotating the processor while lifting it out has the potential to break pins off inside the socket. Lift it straight up. Processors are extremely sensitive to electrostatic discharge. Only handle your processor by its edges. To aid in installation, processors and sockets have a small alignment arrow shown in red so the chip is installed in the correct orientation.
Align the chip so that the arrow in its upper right corner corresponds to the arrow molded into the upper right corner of the socket. Use a small flathead screwdriver to rotate the processor lock degrees clockwise until the indicator points toward the closed lock symbol. Apple uses a thermally conductive film that must be removed prior to reinstalling the heat sink. Use a razor blade or anyother flat object such as a credit card, etc. Next use a small amount of rubbing alcohol to remove all traces of the old thermal material. Apply a thin layer of thermal paste to the reflective silicon face of the processor.
Check out our thermal paste guide for detailed instructions on applying thermal paste. Lay the heat sink on the AirPort card and use a spudger to reconnect the heat sink thermal sensor.
SOLVED: Can the processor be changed? - Mac mini Model A - iFixit
Position the heat sink the same way it will permanently sit before lowering it onto the processor to avoid spreading thermal paste on regions not in contact with the processor. While holding the heat sink in place, press the four plastic posts down through the logic board to reattach the heat sink. I did not complete this guide. I'm learning from cpu-world.
Can the processor be changed?
Does this matter in any way? Hi Richard. Thanks, John.

I'm afraid I can no longer answer the question "does it matter in any way", since I eventually upgraded to a new Mac Mini. Parallels running WinXP and some Windows-only legal software, along with Chrome with far too many tabs open, and iTunes. That proved to be too much, and it'd slow to a crawl too often.
But I think the upgrade kept me on that iMac and extra two or three years, and was an interesting exercise. When going to all the trouble of replacing the CPU, a few other upgrades can be done at the same time:. This guide worked very well for me. Entire process took less than 90 minutes, and that was having to pull the upper frame a second time because I'd let the Airport antenna cable get snagged under the fan ductwork. Select a Language: Help Translate iFixit. Walter Galan and 10 other contributors. Difficulty Difficult. Steps If you already have a Mac, Setup Assistant can help you automatically transfer files, applications, and other information from your previous machine to your new Mac mini.
Note that Setup Assistant makes it easy to copy existing saved settings, files, and folders from your old Mac. It shows the user exactly how to connect your old Mac to a new Mac to migrate the network settings, user accounts, documents, photos, applications, and more. Setup Assistant uses FireWire to transfer your files to your new Mac quickly and easily. Indeed, the user must just follow the onscreen instructions. Setup Assistant can transfer:. Open the Applications folder , then open Utilities , and next double-click the Migration Assistant icon. If you transfer information later using Migration Assistant , make sure FileVault is turned off on the older computer.
Fees may apply. When you have finished working with your Mac mini, you can put it to sleep or shut it down. To put the Mac mini to Sleep: If you will be away from your Mac mini for less than a few days, put it to sleep. When your Mac mini is in sleep, its screen is dark.
