Small black rectangular PWM fan hub with ten 4-pin ports and SATA power connector, magnetic mounting

Cooler Master

Cooler Master 10-port PWM Fan Hub (SATA power)

SKU CH-MHN4-5HKJ7

Connects up to ten PWM fans using a single SATA power cable with magnetic mounting for tidy cable management

  • Controls up to 10 PWM fans from one header
  • SATA power connector feeds all ports directly
  • Magnetic base attaches to any steel chassis surface
  • Compact hub body keeps cable routing tidy
  • Ten 4-pin ports support simultaneous fan operation

Ten-port PWM hub

The Cooler Master hub connects up to ten PWM fans through a single motherboard header. It is built for builders who want centralised speed control without running multiple cables to the board. A SATA power connector supplies the hub directly, keeping the load off the motherboard. The magnetic base lets it attach to any steel surface inside the chassis.

Capacity and headroom

Ten 4-pin ports run in parallel, so every connected fan receives the same PWM signal. The SATA feed handles the combined current of all ten fans under full load. Headroom ends when the total draw exceeds what the SATA line can deliver or when a builder needs independent curves per fan.

What it replaces or upgrades

It replaces a tangle of splitter cables and the limited headers on most motherboards. The jump is worth it when a case holds many fans and the board lacks enough 4-pin headers to control them. It is not for systems that require per-fan speed profiles or builders who prefer software-controlled RGB ecosystems.

Questions about this item

Will the hub draw power from my existing SATA power cables to run ten PWM fans?

Yes, it uses a SATA power connector to supply up to ten PWM fans simultaneously.

How can I verify the hub is controlling fan speeds correctly after installation?

Connect the 4-pin PWM lead to your motherboard header; fan speeds should then respond to BIOS or software curves.

Does the box include mounting hardware such as the magnetic base for chassis attachment?

The hub features a built-in magnetic design that attaches directly to metal surfaces inside the case.
