5-Way 4 Pin PWM Fan Hub Splitter Cable
Expand your PC's cooling potential without sacrificing control. This 5-Way 4 Pin PWM Fan Hub Splitter Cable lets you connect up to five 4-pin PWM fans from a single motherboard fan header — giving you a cleaner build, smarter airflow management, and quieter operation, all in one compact accessory.
Key Features
- 1-to-5 Expansion: One input header splits into five independent 4-pin PWM fan outputs, solving motherboard fan header shortages instantly.
- PWM Intelligent Speed Control: Fully supports PWM (Pulse Width Modulation) signal pass-through, allowing your motherboard to automatically adjust all connected fan speeds based on system temperature — balancing cooling efficiency and noise levels.
- Compact & Lightweight: Measures approximately 7 × 2.3 × 1.1 cm (2.76 × 0.91 × 0.43 in), fitting neatly inside virtually any PC case without cluttering your build.
- Multiple Color Options: Available in 3 color variants to complement your build's aesthetic.
- Plug-and-Play: No drivers or software needed — simply connect and your system recognizes all fans immediately.
- Broad Compatibility: Works with standard 4-pin PWM fans across ATX, mATX, ITX, and most modern PC form factors.
Why Upgrade to a Fan Hub Splitter?
Many motherboards ship with only one or two fan headers, making it impossible to directly connect multiple case fans without losing PWM control. This hub solves that problem elegantly: all five fans remain under the motherboard's intelligent thermal management, so they spin up when your CPU or GPU runs hot and quiet down during light workloads — keeping your system cool and your workspace peaceful.

Frequently Asked Questions
Q: How does the 5-Way 4 Pin PWM Fan Hub Splitter Cable work?
A: The hub connects to a single 4-pin PWM fan header on your motherboard and expands it into five independent 4-pin PWM outputs. Each connected fan receives the PWM signal from your motherboard, allowing automatic speed regulation based on real-time system temperatures — keeping your PC cool and quiet without manual adjustments.
Q: Is this fan hub splitter compatible with my motherboard?
A: Yes — as long as your motherboard has at least one standard 4-pin PWM fan header (found on virtually all modern ATX, mATX, and ITX boards), this hub will work. It is compatible with the vast majority of 4-pin PWM PC case fans from all major brands.
Q: Will all five fans be individually controlled, or do they all run at the same speed?
A: All five fans receive the same PWM signal from the motherboard header they are connected to, so they will respond to temperature changes together as a unified cooling zone. This is the standard behavior for PWM fan splitters and ensures consistent, intelligent thermal management across your entire chassis.
