PC cooling accessory that simplifies fan management by letting a single PWM header control multiple case fans. Gain neater wiring and matched fan speeds with the J&D 4 Pin PWM Splitter Cable. Is a two-pack of 30 cm splitters the sensible choice for larger builds and tidy cable runs?
⚡ At a Glance
- • Fan Control: Synchronous PWM control for up to three fans from one header
- • Best for: PC builders and system enthusiasts who want simple, synchronised fan control
- • Not ideal for: Users who need individual fan RPM control or powered fan hubs
One 4-pin PWM input splits to three fan connectors, including two 3-pin and one 4-pin interface. PVC-sleeved wiring and oxygen-free copper cores improve durability and connection quality.
Synchronised fan speeds – with a 4-pin PWM splitter
A single 4-pin PWM header connects to the splitter and duplicates the motherboard or controller PWM signal to each fan connector, so all connected fans receive the same speed control input. Two 3-pin and one 4-pin connector allow a mix of fan types to be connected.
Matched fan speeds help maintain consistent airflow across the case, reducing hotspots and keeping noise levels in check during heavier loads.
Flexible compatibility – with two 3-pin plus one 4-pin connectors
The cable includes two 3-pin interfaces and one 4-pin interface, and is compatible with most motherboards and fan controllers that support PWM fan control. Passive connection means no special drivers or configuration is required beyond the usual fan header settings.
Mix and match existing fans without changing headers, useful when upgrading or adding extra case fans.
Tidy routing and durability – with 30 cm length and PVC sleeve
Each cable measures 30 cm, suitable for routing behind the motherboard tray or across larger ATX and mid-tower cases, and features a PVC flexible sleeve with oxygen-free copper conductors for stronger connections and reduced wear.
Neater cable runs make builds look cleaner and reduce the chance of loose connections, while durable materials extend service life in everyday use.
✨ The 4 Key Reasons for J&D 4 Pin PWM Splitter Cable
- Two-pack – Spare cable or fit two separate PC builds immediately
- 30 cm length – Reaches behind motherboard tray in larger ATX or mid-tower cases
- PVC flexible sleeve – Protects wires during routing and reduces abrasion risk over time
- Oxygen-free copper – Improves conductivity for stable fan connections under load

❓ Frequently Asked Questions
Q: Can one PWM header control three fans?
A: Yes, the splitter duplicates one 4-pin PWM header to control up to three fans, allowing one header to manage multiple case fans.
Q: Are 3-pin fans supported?
A: Yes, the cables include two 3-pin connectors and one 4-pin connector, making them compatible with both 3-pin and 4-pin fans as described.
Q: Is installation difficult?
A: No special tools or professional knowledge are required; plug the PWM input into the motherboard or fan controller header and connect the fans to the splitter.
🏆 Our Verdict
Suitable for PC builders and system maintainers who want straightforward fan synchronisation without extra hubs. A two-pack with mixed 3-pin/4-pin connectors, PVC-sleeved wiring and oxygen-free copper delivers flexible compatibility and reliable connections. Practical and durable, a small upgrade that expands cooling options without altering motherboard headers.
