PWM Fan Hub – 1-to-3 Port 4-Pin CPU Cooling Splitter Cable
Expand your PC's cooling capability without adding extra motherboard headers. This compact 4-pin PWM Fan Hub splits a single CPU fan header into three independent 4-pin male connectors, letting you run up to three case or CPU fans from one interface. Clean, plug-and-play installation means no drivers, no tools — just connect and go.
Key Features
- 1-to-3 Port Splitter: One 4-pin female input expands to three 4-pin male outputs — ideal for multi-fan setups.
- PWM Compatible: Supports Pulse Width Modulation speed control so all connected fans respond to your motherboard's automatic fan-speed signals.
- 12 V Operation: Designed for standard 12 V PC fan headers found on virtually all ATX motherboards.
- Flexible Extension Cable: Lengthened cable design provides routing flexibility inside your chassis, keeping your build tidy.
- Broad Compatibility: Works with CPU cooler fans, case intake/exhaust fans, and most standard 4-pin PC cooling fans.
- Plug-and-Play: No software or drivers needed — ready to use straight out of the package.

Frequently Asked Questions
Q: What does a 1-to-3 PWM fan hub splitter do?
A: This PWM fan hub takes a single 4-pin fan header on your motherboard and splits it into three 4-pin male connectors, allowing up to three PC fans to share one motherboard interface. All three fans receive PWM speed-control signals, so your motherboard can regulate their speeds automatically.
Q: Is this fan hub compatible with my motherboard?
A: Yes — it is designed to work with standard 12 V, 4-pin PWM fan headers found on virtually all modern ATX and Micro-ATX motherboards. It is compatible with both CPU cooler fans and case fans that use a 4-pin connector.
Q: Do I need to install any drivers or software?
A: No. This is a fully plug-and-play accessory. Simply connect the female end to your motherboard's fan header and plug your fans into the three male outputs. No drivers, software, or additional power connectors are required.
Q: Can I use this with 3-pin fans?
A: The hub outputs 4-pin PWM connectors. Most 3-pin fans will physically connect and operate at full speed, but PWM speed control will only function correctly with 4-pin PWM-compatible fans.
