Expands one PWM header to ten fans, powered by SATA with self-stick mounting
This PWM hub expands a single motherboard header to ten 4-pin connectors so systems with many fans or large radiators can run all units from one control point. It draws 12 V power directly from a SATA 15-pin PSU cable, removing the load from the motherboard. Enthusiasts who need centralised speed management for up to ten fans will find it practical.
Only the red header passes an RPM signal back to the motherboard, so the board can monitor just one fan while the other nine follow the same PWM duty cycle. Three-pin fans connected to any port run at full speed because they lack PWM control. Builders who require individual speed curves or RPM readings for every fan cannot achieve that with this hub.
The board includes a capacitor on each of the ten outputs for stable power delivery. A self-sticker lets you secure the PCB out of sight behind a tray or on a radiator shroud. The 16 inch PWM lead reaches most motherboard headers in mid-tower cases, and the SATA power plug connects directly to the PSU without extra adapters.
Measured against everything we stock in Internal PSU & Riser Cables, at today’s prices. Recalculated every night.

This hub expands one motherboard PWM header to ten fan outputs, each with its own capacitor, and draws 12 V power from a SATA connector instead of the board.
Four-pin fans connected to the hub follow the motherboard PWM curve; three-pin fans run at full 12 V speed because they lack a PWM control line.
All ten fans share the single SATA 12 V rail, so total current draw is capped by that connector and the PSU cable feeding it.
