4-Pin PWM Fan Splitter Cable 1 to 3 Ways – Black Sleeved
4-Pin PWM Fan Splitter Extension Cable – 1 to 3 Ways
Expand your PC cooling setup with this 4-Pin PWM Fan Splitter Extension Cable. Designed to convert a single 4-pin PWM female connector into three 4-pin PWM male outputs, this cable lets you power and control multiple case fans or CPU fans from one motherboard header — keeping your build clean, organised, and fully ventilated.
Key Features
- 1-to-3 Fan Splitter: One 4-pin female input splits into three 4-pin male outputs — ideal for CPU fans and chassis case fans.
- Black Sleeved Design: The braided black sleeving gives a clean, professional look inside any windowed PC case.
- Heat-Shrunk Connectors: Each connector is neatly heat-shrunk for a secure, durable finish that resists fraying and disconnection.
- Oxygen-Free Copper Conductors: Pure oxygen-free copper wiring ensures reliable signal transmission and minimal resistance for consistent PWM fan speed control.
- Universal Compatibility: Compatible with standard 4-pin PWM headers found on most desktop motherboards — works with CPU coolers and 120mm/140mm case fans.
- Approximate Cable Length: 26.5 cm — long enough to reach multiple fan mounting points without excess slack.
Why Choose This PWM Fan Splitter?
Managing multiple fans from a single motherboard header has never been easier. Instead of running separate cables to separate headers (or relying on a fan controller), this splitter delivers clean PWM speed control to all three connected fans simultaneously. The sleeved, heat-shrunk build quality means it looks as good as it performs — a great addition to any custom PC build or cable-managed workstation.

Frequently Asked Questions
Q: What does this 4-pin PWM fan splitter cable do?
A: This 4-pin PWM fan splitter cable takes one 4-pin PWM female input (from your motherboard header) and splits it into three 4-pin PWM male outputs, allowing you to connect and control up to three PWM fans from a single motherboard fan header.
Q: Is this fan splitter compatible with my motherboard?
A: Yes — this cable uses the standard 4-pin PWM connector that is universal across the vast majority of ATX desktop motherboards. It is suitable for CPU cooler fans and standard 120mm or 140mm PC case fans.
Q: What makes the oxygen-free copper wiring important?
A: Oxygen-free copper (OFC) conductors provide lower electrical resistance and better signal integrity compared to standard copper wire. This ensures accurate PWM speed signals are delivered to all three fan outputs consistently, giving you precise fan control without signal degradation.
Q: How long is the cable and will it reach across my PC case?
A: The cable measures approximately 26.5 cm in length. This is sufficient for most mid-tower and full-tower PC cases to reach fan mounting positions near the top, front, or rear panels from a centrally located motherboard header.
