I bought a used I/O board on ebay for $30. Replacing the i/o board solved my problem with the "fan stack" heat sensor which had been unreadable and causing the computer to run very slowly and the fan to run full speed. It was listed like this:
2012 13" MacBook Air MagSafe II DC audio I/O Power Board A1466
HELP NEEDED PLEASE !
While removing the Board I torn apart the pièce at the end of the cable (linked to side) on the l'est of the lasr image. What is it and Howard Can I remplace it ?
