4-Pin PWM Fan Splitter Cable 1-to-4 Ways – 27cm Extension

Keep Your PC Cool & Quiet with This 4-Pin PWM Fan Splitter Cable

Expand your PC's fan connectivity without sacrificing control. This 4-Pin PWM Fan Splitter Cable lets you connect up to 4 fans from a single motherboard header — all while maintaining full PWM speed control for whisper-quiet, temperature-responsive cooling. Available in 1-to-4, 1-to-3, 1-to-2, and 1-to-1 configurations, it's the perfect cable management solution for any build.

Key Features

• Flexible Configurations: Choose from 1-to-4, 1-to-3, 1-to-2, or 1-to-1 splitter options to suit your exact fan setup.
• Full PWM Support: All 4 pins pass through PWM signal so your motherboard retains full control over fan speed — no more always-on fans running at full throttle.
• 27cm Extension Length: Generous cable length gives you the slack needed to route cables cleanly through your case without strain or tension.
• Black Sleeved Design: Premium black mesh sleeving protects wiring and adds a clean, professional look to your build.
• Universal Compatibility: Works with all standard 4-pin PWM PC case fans, CPU coolers, and motherboard headers.
• Durable Connectors: Solid plastic locking connectors ensure secure, stable connections that won't accidentally disconnect.

Why PWM Matters for Your PC

PWM (Pulse Width Modulation) fan control allows your motherboard to dynamically adjust fan speeds based on temperature sensors. This means quieter operation when your PC is idle and maximum airflow when it's under load — all without manual intervention.

Frequently Asked Questions

Q: Will this 4-pin PWM fan splitter work with 3-pin fans?

A: Yes! While this cable is designed for 4-pin PWM fans, it is backward compatible with 3-pin fans. Note that 3-pin fans connected via this splitter will run at a fixed voltage rather than PWM-controlled variable speeds.

Q: Can I run multiple fans from one motherboard header using this PWM splitter?

A: Yes. The 1-to-4 version lets you connect up to 4 PWM fans to a single motherboard fan header. Just ensure your motherboard header can support the combined amperage of all connected fans (most headers support up to 1A; check your motherboard manual).

Q: Is the PWM speed signal maintained across all split outputs?

A: Yes. This is a true PWM splitter — the PWM control signal is distributed to all output connectors, so your motherboard retains full speed control over all connected fans simultaneously.

Q: What does the black sleeving on the cable do?

A: The black braided mesh sleeving provides both protection from cable abrasion and a cleaner, more professional aesthetic inside your PC case. It helps with cable management and reduces clutter.
