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.
