Our 2.5 mm nut driver makes a rare appearance (you may remember its role in the Demontage van de iPhone 6s)—removing logic board standoff screws. Thanks to our iPhone Marlin kit, we're covered!

The fanless M1 MacBook Air-sized logic board is housed in the artificial "chin" of the iMac.

Unlike the one in the MacBook Air, this M1 is actively cooled by a pair of fans. Each fan blows inward across the logic board, where the heatsink draws heat away from the M1 with a copper heat pipe and two short heatsinks.

We'll circle back later for a closer look at those fans, but we can't resist a bare logic board!
