8-Port 4-Pin PWM Fan Hub Splitter Regulator 12V CPU

Expand your PC cooling system with ease using this 8-Port 4-Pin PWM Fan Hub Splitter & Regulator. Designed for desktop PC builders and enthusiasts, this hub lets you connect and control up to eight 4-pin PWM fans simultaneously from a single motherboard header — keeping your build cool, quiet, and organized.

Built with oxygen-free copper wiring for reliable signal and power transmission, this fan hub reduces the load on your motherboard by drawing power directly from a 12V molex connector. The result is better fan longevity, a healthier motherboard, and full PWM speed control across all connected fans from a single signal source.

Key Features

• 8 × 4-Pin PWM Fan Ports — Connect up to eight fans simultaneously with full PWM speed regulation
• 12V Molex Power Input — Powers fans directly from your PSU, reducing motherboard header load
• Single PWM Signal Control — All fans respond to one PWM signal from your motherboard for synchronized speed management
• Oxygen-Free Copper Conductors — Ensures low-resistance, high-quality power and signal delivery
• Compact & Lightweight Design — Easy to mount or tuck away neatly inside any PC case or chassis
• Universal Compatibility — Works with standard ATX desktop cases, CPU coolers, and case fans
• Packaged in Pearlescent Film Bag — Protected and ready for gifting or storage

Frequently Asked Questions

Q: What does the 8-Port 4-Pin PWM Fan Hub Splitter do?

A: This PWM fan hub allows you to connect up to eight 4-pin PWM fans to a single motherboard fan header. It draws its power from a 12V molex connector on your power supply, significantly reducing the load on your motherboard. All fans are regulated by a single PWM signal, enabling synchronized speed control for efficient and consistent cooling throughout your PC case or chassis.

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

A: Yes — this hub is compatible with any standard ATX desktop PC that uses 4-pin PWM fans. It works with CPU coolers, case fans, and chassis cooling setups. Simply connect the molex power cable to your PSU, plug the PWM signal cable into your motherboard's CPU or system fan header, and attach up to eight fans to the output ports.

Q: What material are the cables made from?

A: The cables feature oxygen-free copper conductors, which provide superior electrical conductivity, minimal signal loss, and long-term durability — making them a reliable choice for continuous 24/7 operation in a desktop PC environment.

Q: Will all fans run at the same speed using this hub?

A: Yes. All connected fans receive the same PWM signal from your motherboard header, so they operate in unison. This makes it easy to manage overall system cooling with a single fan curve set in your BIOS or fan control software.
