  • Triple Fan Connection Solution: The 4 pin fan splitter cable connects up to 3 computer case fans to a single motherboard fan header. This PWM splitter cable lets you add an additional fan to improve airflow inside your PC. A fan speed label on the 4 pin master connector of the fan header splitter is wired to receive the PWM control signal and distribute it to all slave fans for synchronized cooling.
  • Unified PWM Control: The 3 way fan splitter (also known as a motherboard fan splitter, CPU fan splitter, or PC fan splitter 4 pin) connects to a 4-pin motherboard header and splits the signal across 3 PWM fans. Control fan speed uniformly through motherboard software for efficient, balanced cooling performance.
  • Synchronized Speed Management: The 4pin fan splitter features one 4-pin connector that sends the RPM signal back to the motherboard to synchronize fan speed across the other two fans. The 3 pin fan splitter omits the RPM signal pin, allowing all connected fans to run in tandem when supported by your systemperfect for setups where you need to daisy chain PC fans for optimized airflow.
  • Spare Cable Convenience Pack: This cost-effective 2-pack of computer fan splitter 4 pin cables includes a spare for future upgrades or extra fans. Each sleeved and wrapped black 12-inch case fan splitter cable provides a clean, professional look inside an open PC case and helps organize your cable management.

Description

Cable Matters, with headquarters in Southborough, Massachusetts, offers a complete line of cables, adapters, docking stations, and networking products for the home, office, and data center. Cable Matters offers first-class, quality, and affordable products backed by an exceptional customer experience. How many fans can I connect with this PWM fan splitter? Each 12-inch splitter connects up to three standard PC fans to one 4-pin motherboard fan header. The package includes two splitter cables. It works with compatible case, CPU cooler, and radiator fans that use standard 3-pin or 4-pin fan connectors. Why do two fan connectors appear to be missing one pin? This is ot a defect. Only the labeled Master connector includes the RPM feedback pin, preventing multiple fan speed signals from conflicting at one motherboard header. Connect the fan you want the BIOS or software to monitor to the Master connector. Will all three 4-pin PWM fans change speed together? Yes, but all connected 4-pin PWM fans receive the same PWM control signal and adjust speed together. And the motherboard displays the RPM of only the fan connected to the Master branch. Can I connect 3-pin fans to this splitter? Yes, but 3-pin fans do not support PWM speed control. They may run at full speed when the motherboard header is set to PWM mode. If the motherboard supports DC or Voltage mode, all connected 3-pin fans may be adjusted together through the BIOS. Can one motherboard fan header safely power three fans? Check the motherboard specs and add the rated current of all connected fans. The total must remain within the fan header’s limit. This splitter has no SATA or Molex power input; use a powered PWM hub if the combined load is too high. 3 Way Fan Splitter Cable 2 Way Fan Splitter Cable PWM Extension Cable PC Case PWM Fan Hub PWM Extension Cable PCIe to Dual PCIe Adapter

Good quality cable and reliable too
When one needs to increase the number of fans, this is what you want. Good quality construction and good lead lengths make this a cable worth using.

Essential for ITX Builds—Reliable Fan Splitters for Tight Spaces
I picked up this 2-pack of Cable Matters 3-way 4-pin PWM fan splitter cables for my latest ITX build, and honestly, they made all the difference. When you’re working inside a really compact case, cable management is everything, especially if you’re adding extra fans for proper airflow. I needed to connect several 80x10mm fans for top exhaust and side intake, and there’s no way I could’ve done it without these splitters. The extra length (12 inches / 30cm) made routing the cables way easier and helped keep everything neat, which also helps airflow. Both my top exhaust and side intake fans are still spinning strong, and I haven’t run into any issues with power delivery or weird RPM drops, everything just works. If you’re working in a small form factor case, good fan splitters like these are a must-have. Great value for how good they are. I build PCs for gaming and content creation, so cooling is a priority, especially in tight ITX setups. These splitters let me run more fans safely without overloading my motherboard headers, and they made it possible to squeeze out better temps without a mess of tangled wires. Overall, highly recommended for anyone doing an ITX or small form factor build. Solid build quality, reliable performance, and they just make cable management way easier. If you care about airflow and cooling, don’t skip these! ... show more

Nice option for a cheap splitter.
Nice quality, compatibility for 4 PIN. Nice material, long for my fans. In my opinion nice price for a good material. Super flexible.

Works perfectly and feels high quality!
These cable splitters are well made and worked exactly as expected. The connections are secure, the cables feel durable, and installation was quick and easy. They provide reliable performance and are an excellent value for the price.

Must need for PC
It came with 2 cables, and the price is great. If you know how to install it will be easy to connect up to 3 fans with the cable. Its sleek black design and durable insulation will last a long time. Easy to connect to fan and motherboard

Perfect for a clean set up
One of the three connectors is a full 4-pin that reports the fan speed back to the motherboard, while the other two are 3-pin (they still get the 4-pin PWM signal for speed control). This allows your motherboard to control all three fans as a single unit, ramping them up or down together based on temperature. The build quality is great—the black braided sleeving looks clean and is easy to route, and the connectors feel solid and secure. The length is perfect, and the value for quality is 10/10. ... show more

Good multifan connector
This was exactly what I needed to plug multiple fans into my motherboard. It worked as intended and is a high quality cable. Would definitely buy again if I needed more.
