4-Pin 1-to-3 PWM Fan Power Splitter Cable for Desktop PC
4-Pin 1-to-3 PWM CPU Fan Power Splitter Cable
Expand your desktop PC's fan connectivity without hassle. This 4-Pin PWM 1-to-3 fan power splitter cable by OULLX lets you connect three case fans to a single motherboard fan header — no extra adapters or hubs needed. Braided with durable snake-skin sleeving and built with tinned copper conductors, it delivers reliable, stable power to all your cooling fans simultaneously.
Key Features
- 1-to-3 Fan Split: One 4-Pin PWM motherboard connector splits into three 3-Pin fan outputs — power three fans from one header.
- Braided Sleeving: Protective snake-skin mesh outer jacket keeps cables organized and resistant to wear.
- Tinned Copper Conductors: Corrosion-resistant tinned copper (11×0.12TS) ensures excellent conductivity and longevity.
- Compact & Lightweight: Just 27–30 cm in length and 16 g — fits neatly inside most mid-tower and full-tower cases.
- Universal Compatibility: Works with most standard desktop PC motherboards featuring a 4-Pin CPU/system fan header.
- CE & RoHS Certified: Meets international safety and environmental standards — no high-concern chemicals used.
- No Assembly Required: Plug-and-play design — ready to use straight out of the package.

Frequently Asked Questions
Q: Will this 4-Pin PWM fan splitter cable work with my motherboard?
A: Yes — this cable is designed to work with standard desktop PC motherboards that have a 4-Pin CPU or system fan header. The input is a 4-Pin connector, and it splits into three 3-Pin fan outputs, making it compatible with the vast majority of ATX, Micro-ATX, and Mini-ITX boards.
Q: Can I run three fans at full speed using this splitter cable?
A: The splitter shares the power from a single motherboard fan header across three fans. It is recommended to use fans with a combined current draw within your motherboard fan header's rated output (typically 1A). For best results, use lower-draw fans or check your motherboard manual for the maximum header amperage before connecting multiple fans.
Q: Does this cable support PWM fan speed control on all three outputs?
A: The input side is a 4-Pin PWM connector; however, the three output connectors are 3-Pin. This means fan speed control via PWM signal is not passed to the output fans — the fans will run based on voltage control. The cable is ideal for ensuring all three fans receive stable power from one header.
Q: How long is the cable and will it reach fans at the top or front of my case?
A: The cable measures 27–30 cm (approximately 10.6–11.8 inches) in length. This is sufficient for most mid-tower case fan placements near the motherboard fan header, though very large full-tower cases may require additional cable management or extension.
