-[* red] Loosen but do not remove the four captive T9 screws securing the heat sink over the CPU.
+[* red] Fully loosen the three captive T9 screws securing the heat sink over the GPU.
[* orange] Remove the two 5.4 mm T9 screws securing the heat pipe to the logic board.
-[* icon_note] Some iMac models have a straight heat pipe rather than a curved one—regardless, the screws will be the same size/type and the ones over the CPU will be captive to the heat sink.
