Cooler Master MFX-ZHHN-1NNN6-R1 ARGB PWM Hub 6-Port Fan Controller

The Cooler Master MFX-ZHHN-1NNN6-R1 ARGB PWM Hub is a compact controller designed to expand your motherboard's fan and lighting connectivity. It provides six 4-pin PWM fan headers and six 3-pin addressable RGB headers, allowing you to connect up to twelve devices from just one PWM fan header and one ARGB header on your motherboard. Power is supplied through a single SATA connector from your PSU, and the hub is rated to maintain stable output even under full load across all ports, so you do not need to worry about voltage drops when running multiple fans and LED strips simultaneously.

Installation is straightforward thanks to built-in magnets that let you attach the hub to any steel surface inside your case without screws, brackets, or adhesive tape. Its small footprint means it tucks easily behind a cable management panel or onto a drive cage, keeping your build clean. The hub passes through whatever PWM signal your motherboard sends, so fan speed is controlled by your existing BIOS or software fan curves. Similarly, ARGB lighting is managed through your motherboard's compatible software — the hub itself does not process or modify the lighting signal, it simply distributes it to all connected devices in sync.
