40 cm PWM Fan Hub Splitter
This 40 cm cable turns one motherboard 4-pin header into five fan connections. It is aimed at PC builders who need to run several case or CPU coolers from a single PWM source. The hub handles both 3-pin and 4-pin fans for mixed cooling setups.
Oxygen-Free Copper Wires in Nylon Mesh
Each lead uses 22 AWG 1007 wire with 17 strands of 0.12 mm tinned copper wrapped in black PVC insulation. The 40 cm loom is sheathed in a wrapped nylon mesh that resists abrasion and keeps routing tidy inside the chassis. Five connectors join at a compact 5 cm by 1.8 cm hub block.
Passive Hub Runs Cool and Quiet
No active electronics mean the adapter adds no fan noise and draws no extra power beyond the fans themselves. Wires are rated for 80 °C continuous operation so they stay safe near hot components. The first port passes the CPU fan signal while the remaining four provide standard PWM control.

Questions about this item
Does the 4-pin PWM hub pass speed control to all five fan headers?
Yes, the hub connects to the motherboard 4-pin CPU fan header and forwards the PWM signal to each of the five outputs so every attached fan responds to the same speed curve.
What clearance does the 5 cm × 1.8 cm hub housing need inside the case?
The hub body measures 5 cm long by 1.8 cm wide, so allow at least that much flat space behind the motherboard tray or in a cable-routing channel for the connector block to sit without bending the 40 cm leads.
Which header should I plug the CPU cooler into for proper RPM reporting?
Connect the CPU cooler to the dedicated first header labelled for the CPU fan; the remaining four headers are standard PWM fan outputs that follow the same signal but do not report speed back to the motherboard.
