Fancasee 4-Pin PWM Fan Power Supply Cable 1 to 5 Splitter 5 Way PC Case Internal Motherboard Fan Power Extension Cable Cord Wire for ATX Computer Case 4-Pin and 3-Pin Cooling Fans (13 inch, Black) 4.7 out of 5 stars 1,109. The chassis fan controller has 3x4pin and 3x3 pin fan headers that's why I haven't used it for all 6 fans. They are all full power 4pin Corsair ML120 rated for 2400rpm. I agree that SATA for power and mobo fan header for PWM control makes the most sense.

Notes
Fan Header On Motherboard
- Colors may change.
- Chassis and CPU fans may use either 3-pin or 4-pin powerconnectors. 3-pin connectors are usually used for the smallerchassis fans with lower power consumption. 4-pin connectors areusually used by CPU fans with higher power consumption. Fans andon-board fan headers are backwards compatible. Proper fan connectorplacement is shown in the figures below:
- Fan has a 3-pin power connector; desktop board has a 4-pin fanheader: Note: when using a 3-pinpower connector with a 4-pin fan header, the fan will always be on;there is no fan control.
- Fan has a 4-pin power connector; desktop board has a 3-pin fanheader:
