5-Way 4 Pin PWM Fan Hub Splitter Cable | Multi-Fan Expansion

5-Way 4 Pin PWM Fan Hub Splitter Cable

Expand your PC's cooling potential with this 5-Way 4 Pin PWM Fan Hub Splitter Cable. Designed for builders and enthusiasts who need to run multiple case fans from a single motherboard header, this compact hub lets you connect up to five 4-pin PWM fans simultaneously — no more hunting for spare headers or sacrificing speed control.

Key Features

• 1-to-5 Expansion: One motherboard fan header powers up to five 4-pin PWM fans at once, giving you full chassis fan flexibility without extra adapters.
• PWM Intelligent Speed Control: Fully supports PWM signal pass-through, so your motherboard's fan curve automatically adjusts each connected fan's speed — keeping your system quiet under light loads and cool under heavy ones.
• Reduced Operating Noise: Because the hub respects your motherboard's PWM signal, fans ramp up only when needed, significantly lowering overall system noise.
• Compact & Versatile: Measures just 7 × 2.3 × 1.1 cm (approx. 2.76 × 0.91 × 0.43 in), fitting neatly inside virtually any ATX, mATX, or ITX case without cable clutter.
• Multiple Color Options: Available in 3 color variants to complement your build's aesthetic.
• Plug & Play: No drivers or software required — connect and go straight out of the box.

Frequently Asked Questions

Q: How many fans can I connect to this 4-pin PWM fan hub splitter?

A: This hub features a 1-to-5 design, allowing you to connect up to five 4-pin PWM fans from a single motherboard fan header. This makes it ideal for builds that require extensive cooling without enough onboard headers.

Q: Does this fan hub support PWM speed control for all connected fans?

A: Yes. The hub passes the PWM signal from your motherboard to all five connected fans, enabling automatic speed adjustment based on your motherboard's fan curve settings. All fans will respond to the same PWM signal, keeping your system cool and quiet as needed.

Q: Is this fan splitter compatible with my PC case and motherboard?

A: This splitter is compatible with any motherboard that features a standard 4-pin PWM fan header and works with virtually all ATX, mATX, and ITX cases. It is plug-and-play with no software or drivers needed — simply connect the hub to your motherboard header and plug in your fans.
