Cooler Master ARGB & PWM Hub — 1 to 6 Port Fan/LED Splitter

The Cooler Master ARGB & PWM HUB is a compact controller that expands one ARGB and one PWM header into up to six ports, letting you power and synchronize multiple fans and addressable LEDs with tidy cable management.

Designed for builders who need more fan and lighting connections than their motherboard provides, this hub combines addressable RGB (3‑pin) and PWM distribution in a small, magnet‑mountable unit. It uses a single SATA power feed to maintain stable output even when all six ports are occupied, making it a practical way to scale cooling and lighting while keeping the interior of your case neat.

How many fans and ARGB devices can this hub control at once?

The hub splits one PWM header and one 3‑pin addressable RGB header into six paired outputs, so you can connect up to six compatible fan and ARGB sets. Each set receives PWM for speed control and a 3‑pin ARGB signal for independent lighting effects (assuming your motherboard/software supports addressable RGB).

• Six PWM fan connectors (shared single PWM input)
• Six 3‑pin 5V ARGB connectors for addressable lighting
• Requires one motherboard PWM header and one 3‑pin ARGB header
• Powered by a single SATA power cable for stable delivery

Will it fit inside my case and how do I mount it?

The hub is intentionally compact and includes built‑in magnets that fasten to any metal surface inside your case, so installation is tool‑free and reversible. Its small footprint also helps keep cable runs short and organized behind drive cages or along the chassis interior.

• Compact form factor fits behind motherboard tray or drive bays
• Integrated magnets for quick mounting to steel surfaces
• Short connector cables reduce clutter and improve airflow

Does it require additional power and is output stable under load?

The hub is powered by a SATA power connector to supply consistent power when multiple fans and LEDs are connected. Cooler Master designed the unit to maintain stable PWM and ARGB signals even when all six ports are used, preventing dimming or erratic fan behavior associated with insufficient power.

• SATA power input supplies steady voltage under full load
• Maintains reliable PWM speed control across all connected fans
• Preserves ARGB signal integrity for consistent lighting effects

How does this hub affect cable management and system airflow?

By consolidating multiple fan and LED cables into a single, centrally mounted unit, the hub reduces the number of long cable runs and messy splitters. Cleaner cable routing improves airflow and makes future upgrades or troubleshooting easier.

• Reduces clutter with grouped fan and ARGB connections
• Shorter cables improve airflow and simplify routing
• Magnetic placement lets you position the hub for optimal tidy runs

Who this is for: The Cooler Master ARGB & PWM HUB is ideal for PC builders who want to add multiple ARGB fans and maintain centralized PWM control without extra wiring chaos. If your motherboard has limited headers but you plan to install three or more ARGB fans, or if you prioritize clean cable management and reliable power delivery, this hub provides a straightforward, compact solution.
