freestanding four-pin plug when we're done with the build and ready to put
the sides back onto the PC case.
We have one more built-in case fan to power, that being the fan in the back
of the case near the motherboard's I/O shield. Just as we did for the CPU
fan, locate the end of the wire coming from the rear case fan and note its
three-pin connector. Attach this connector to the four-pin CHA FAN three-
pins near the rear of the motherboard. Refer to the next two figures showing
the before-and-after view of the attached wire.

erboard.
Figure 33—The rear case fan wire is connected and ready for a spin.
