Unsnap the two coaxial connectors from the motherboard.

To avoid damaging the wires, wedge a spudger under their rounded, metal ends and gently pop them up from the motherboard one at a time.

Unhook the coaxial wires from the side of the fan by gently pulling them downward and away from the hooks.

During reassembly, these two wires can be surprisingly difficult to reconnect to the motherboard. The easiest method is to hold the wires in place over their terminals and click the metal bases down with the tip of a spudger.
