4-Pin PWM CPU Fan Hub – Smart Chassis Cooling Controller

Upgrade your PC's airflow management with this 4-Pin PWM CPU Fan Hub. Designed to solve the common problem of limited motherboard fan headers, this metal-built hub lets you connect and control multiple chassis fans from a single CPU fan interface — all while keeping your build clean and organised.

Key Features

Expands Fan Connectivity: Consolidates multiple fan cables into one tidy hub, eliminating clutter inside your case and freeing up precious motherboard headers.
PWM Speed Control: The PWM interface connects directly to your motherboard's CPU fan header, allowing intelligent, automatic fan speed regulation based on system temperature.
Dedicated CPU Fan Port: The red-marked port is reserved exclusively for your CPU fan and includes a speed measurement (RPM monitoring) function so your system always knows the fan is spinning.
Durable Metal Construction: Built from sturdy metal for long-lasting reliability inside your chassis.
Available in 2 Colour Options: Choose the finish that best complements your build aesthetic.
Easy Installation: Plug-and-play design fits standard ATX cases — no tools or drivers required.

Frequently Asked Questions

Q: What does a 4-Pin PWM CPU Fan Hub do?

A: A 4-Pin PWM CPU Fan Hub expands your motherboard's single CPU fan header into multiple fan ports. This allows you to connect and control several chassis fans simultaneously through one PWM-enabled header, enabling automatic speed control based on your PC's operating temperature.

Q: How does the dedicated CPU fan port with speed measurement work?

A: The red-marked port on this fan hub is specifically designed for your CPU fan. It passes the RPM (speed) signal back to the motherboard, so your BIOS and monitoring software can accurately read the CPU fan speed and trigger alerts if the fan ever stops spinning — an important safety feature for your system.

Q: Is this fan hub compatible with my PC case?

A: This fan hub is compatible with most standard ATX PC cases that use 4-pin PWM fan connectors. Simply connect the hub's PWM cable to your motherboard's CPU fan header, then plug your chassis fans into the hub's output ports. No special drivers or software are needed.

Q: What is the fan hub made of?

A: The fan hub is constructed from durable metal, ensuring it holds up well to the heat and vibration inside a PC case over extended use.
