4-Pin 3-Way Y Splitter Fan Cable for PC & Notebook
4-Pin 3-Way Y Splitter Fan Cable for PC & Notebook
4-Pin 3-Way Y Splitter Fan Cable — One Header, Three Fans
Expand your PC's fan connectivity without adding extra motherboard headers. This 4-pin PWM 3-way Y splitter cable lets you power and control up to three case fans — 4-pin or 3-pin — from a single CPU or chassis fan header, keeping your build tidy and your airflow optimized.
Why This Splitter Stands Out
- Premium tinned-copper conductors — low-resistance connections for stable, consistent fan power delivery.
- Braided outer sleeve — the wire jacket adds a clean, professional look inside your case while protecting the cable from wear.
- Advanced welding & injection-molded connectors — the SATA-to-fan junction uses a modern welded and overmolded process (replacing the older crimped-copper-buckle method) for greater durability and a cleaner finish.
- Universal 4-pin PWM & 3-pin compatibility — works with standard PC case fans, CPU coolers, and notebook cooling pads that use 4-pin or 3-pin connectors.
- Plug-and-play — no drivers, no tools; just connect and go.

Frequently Asked Questions
Q: How many fans can I connect with this 4-pin 3-way Y splitter cable?
A: This splitter lets you connect up to three fans — either 4-pin PWM or 3-pin fans — from a single 4-pin fan header on your motherboard, effectively tripling your fan connectivity from one header.
Q: Will this 4-pin fan splitter work with both 4-pin and 3-pin fans?
A: Yes. Each of the three output connectors on this Y splitter cable is compatible with standard 4-pin PWM fans and 3-pin DC fans, making it a versatile addition to any PC or notebook cooling setup.
Q: What makes the connector quality better on this splitter cable?
A: Unlike older-style cables that used a crimped copper buckle at the SATA-to-fan junction, this splitter uses an advanced welding and injection-molding integrated process, producing a more durable, cleaner-looking connection that holds up better over time. The tinned-copper conductors and braided outer sleeve further enhance both performance and aesthetics.
