The motherboard fan connectors are:
CPU_FAN - CPU cooling tower;
CPU_OPT - CPU colling tower;
CHA_FAN1 - fan wire splitter - 3 wires - rear,
- 2 wires - projector extra;
CHA_FAN2 - front high;
CHA_FAN3 - front low.
All connectors are 4-pin. "Projector extra" is a fan
located outside the computer.
I would disconnect the fan wire splitter, disconnect projector extra
fan, and connect the Corsair fan directly to CHA_FAN1:
CPU_FAN- CPU cooling tower - be quiet! Pure Wings 2, 120 mm, 4-pin
CPU_OPT - CPU cooling tower - be quiet! Pure Wings 2, 120 mm, 4-pin
CHA_FAN1 - location? - Corsair, 120 mm 3-pin
CHA_FAN2 - front high - be quiet! Shadow Wings 2, 140 mm, 4-pin
CHA_FAN3 - front low - be quiet! Shadow Wings 2, 140 mm, 3-pin
It is unwise to power external devices from a computer motherboard. I
would get a 12 VDC power adapter with suitable ampere rating for the
projector extra fan.
