    • Grab all the wires at once and gently pull straight up to disconnect the fan from the logic board.

    • Do not pry at the socket, or you may rip it from the logic board.

    • Remove the fan.

  6. Mac mini Late 2012 Logic Board Replacement, Cowling: étape 6, image 1 de 1
    • Remove the single 3.5 mm T6 Torx screw securing the cowling to the heat sink.

  7. Mac mini Late 2012 Logic Board Replacement: étape 7, image 1 de 1
    • Lift the cowling from the end nearest the antenna plate.

    • Rotate the cowling away from the outer case and remove it from the mini.

  8. Mac mini Late 2012 Logic Board Replacement, Antenna Plate: étape 8, image 1 de 1
    • Remove the following screws securing the antenna plate to the mini:

    • Two 6.6 mm T8 Torx screws

    • Two 5.0 mm T8 Torx or 2.0 mm Hex screws (either screwdriver will work)

    • When putting back together:

    • It can be difficult to get the hard drive seated correctly such that the antenna plate fits in place correctly. If the screw holes don't line up with those on the hard drive, make sure that the two pins that are in the back of the hard drive are properly seated in the holes at the back of the case, above the housing for the second hard drive.

    • The antenna attaches directly to the hard drive (red markers), therefore attaching the antenna can move the hard drive around and loosen the connection of the hard drive cable to the logic board.

  30. Mac mini Late 2012 Logic Board Replacement: étape 30, image 1 de 1
    • Remove the heat sink from the logic board, minding any cables that may get caught.

    • If the heat sink appears to be stuck to the logic board after removing all screws, it may be helpful to use a spudger to separate the two components.

    • If you need to mount the heat sink back onto the logic board, we have a thermal paste guide that makes replacing the thermal compound easy.

    • Logic board remains.

Conclusion

To reassemble your device, follow these instructions in reverse order. Be sure to follow our thermal paste guide to reapply the thermal compound on the CPU.

I ran a hardware test on my MacMini 2012 an it gave me the error 4SNS/1/C0000008: TAOP--124. I cannot use the Mac mini anymore because the fan is on full speed and kernel_task is on >300%.

I already know that the error is the Ambient Temperature sensor but i haven't got any hint where it is located. Similar threads on forums are always about MacBooks.

Do you know wether this sensor is on the logic board or is it external? What sensors does the Mac mini 2012 has?

Many thanks.

Just a heads up, after step #15, before #16, fishing out the hard drive makes pulling the DC-In cable to the Logic Board exponentially easier.

Step 17 shows the logic board being removed with the port cover intact. Step 30 shows the logic board without the port cover. There’s no mention in between of how that cover comes off. Anyone?

Deroute the wifi cables. You will see a connector to the board on its underside for the wifi: pry up from underneath the cable to free the connector from the board. Then there's 5 T6 screws to remove, 4 on the underside, one on the top. Now there's a small insulator glued to the board between the card reader and USB ports. Pull that off. You'll need to glue that back upon reassembly. Next, you gently wiggle the board away from the port cover. I would do this upside down from the orientation of the last picture, as there are 3 foam insulators that will fall out if you do it the other way. They are not connected at all, so be prepared for them to move around as soon as the board is loose. Reverse to put it back together.
