  • Lift the logic board out of the midplane. Careful, there is a light guide on the lower left that can tear if you are not careful. This guides the light to the power-on light at the front of the iMac.

  • When reinstalling your logic board, be sure to clean and apply a new layer of thermal paste to the U3 chip (highlighted in red) located on the underside of your logic board as well as its heat sink attached to the midplane.

  • We have a thermal paste guide that makes applying thermal paste a snap.
