Common Applications

The SC-HUB consolidates up to five 4-pin PWM fans (or a pump plus four fans) onto a single motherboard fan header. Power for the connected devices is drawn from a SATA cable off the PSU, while a 4-pin PWM lead from the hub plugs into the motherboard's CPU_FAN or system fan header to relay the PWM duty cycle and tach signal from the first port. The PCB measures 70 x 23mm and ships with double-sided foam tape for mounting inside the case. The included PWM cable is roughly 39.5cm long, which reaches the CPU fan header from most radiator mount locations.

Frequently Asked Questions

Q: How does the SC-HUB get its power?

A: From a SATA connector off the power supply, so it never overloads the motherboard fan header.

Q: How many fans can I connect?

A: Five 4-pin PWM channels. A pump can take one of the channels if it draws 4-pin PWM control.

Q: Can I connect 3-pin DC fans to it?

A: Yes, 3-pin fans will run at full speed because PWM controls the 4th pin only. Use 4-pin PWM fans for variable speed.

Q: Where does the PWM signal come from?

A: From the motherboard header the hub's PWM cable plugs into, typically CPU_FAN. The hub passes that single PWM duty cycle to all connected fans.

Q: What is included in the box?

A: The 70x23mm hub PCB and a roughly 39.5cm 4-pin PWM cable. Mounting tape is included for case-side mounting.
