Fan hub Singularity Fan-Node 2x4 SC-PWM-N-2x4 — PWM splitter for 2×4-pin fans

Singularity Fan-Node 2x4 is a compact PWM fan hub that splits a single 4‑pin PWM signal into two groups of four 4‑pin fan connectors. Designed for PC builders who need centralized fan speed control and tidy cable routing, this splitter allows multiple case or radiator fans to be managed from one motherboard header or compatible controller. The device provides synchronized PWM control while delivering power to each connected fan through individual 4‑pin sockets.

Advantages

The Fan-Node 2x4 supports synchronized PWM signaling to ensure consistent fan speed across connected fans, reducing noise variation and simplifying cooling management. Its compact form factor and clearly arranged connectors make cable routing easier and help maintain a clean build. The hub distributes power to up to eight 4‑pin fans while requiring only a single PWM input, which minimizes header usage on the motherboard or controller.

Suitable for

• Custom PC cases with multiple intake and exhaust fans
• Radiator setups with several fans per radiator
• Small form factor builds where motherboard header count is limited
• Systems where synchronized fan speed and neat cable management are desired

Key specifications

• Input type: single 4‑pin PWM signal
• Output connectors: two groups of four 4‑pin fan sockets (total 8 outputs)
• Control: PWM speed control replicated across outputs
• Power distribution: dedicated power lines to each fan connector
• Form factor: compact hub designed for internal PC mounting

How to use

Connect the hub's PWM input cable to a motherboard 4‑pin PWM header or to a compatible PWM controller. Plug up to eight 4‑pin PWM fans into the available fan sockets, dividing them between the two groups as needed. Ensure each fan is compatible with 4‑pin PWM control. After connection, configure the motherboard or controller fan profile to manage the collective fan group through the single PWM source. Check that the total current draw of connected fans does not exceed the power capability of the system supply and motherboard header used to feed the hub.
