  8. Mac mini Late 2012 Heat Sink Replacement, Antenna Plate: adım 8, 1 resimden 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.

    • To remove the logic board, the two cylindrical rods of the Mac mini Logic Board Removal Tool must be inserted into the holes highlighted in red. Inserting instruments into any logic board holes other than the ones highlighted in red may destroy the logic board.

    • Insert the Mac mini Logic Board Removal Tool into the two holes highlighted in red. Be sure it makes contact with the top side of outer case below the logic board before proceeding.

    • Carefully pull the tool toward the I/O board. The logic board and I/O board assembly should slightly slide out of the outer case.

    • 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.

When reinstalling the heatsink the Platform controller chip has a huge gap, so you have to either use a thermal pad, ton of thermal paste or shim the gap. I ended up using a shim made out of a soda can. I posted photos here:

There is no need for the controller to be cooled. It is the same with the MacBooks of that time. The controller chip isnt even covered by the heatsink.

Hello,

I'll refresh this thread a bit - I replaced the thermal paste on the processor and since then my Mac mini patch 2012 has been raging at tepmperatures between 70 and 100 degrees. What could I have screwed up? The system laughs like crazy, I rebooted and PRAM and SMC and tried with SAFE MODE , changed the paste again and same thing. Do you have any experience with this type of problem?
