Black 40cm mesh cable with 5 4-pin fan connectors and Molex plug

Ruth's sister

Ruth's sister 40cm 1 to 5 4-pin Molex TX4 PWM Fan Hub Splitter Adapter

SKU CH-GDDJ-ZJFEX

A 40 cm Molex-powered hub splits one motherboard PWM header into five 4-pin fan connectors

  • Connects up to five PWM fans from one header
  • 40 cm cable length reaches across full-tower chassis
  • Molex power input supports high-draw fan arrays
  • Back-adhesive pad secures hub without extra hardware
  • Only the CPU-fan port reports RPM to the motherboard

40 cm PWM fan hub for CPU and case cooling

This 40 cm adapter splits a single motherboard 4-pin PWM header into five fan connections. It is built for PC builders who need to run multiple CPU or chassis fans from one controlled header. The hub weighs 14 g and includes adhesive backing for secure mounting inside the case.

Motherboard 4-pin PWM header required for speed

The hub itself does not regulate fan speed; it passes the motherboard's PWM signal to all connected fans. Only the fan plugged into the designated CPU connector reports its speed back to the board. Four-pin fans receive full PWM control, while three-pin fans run at fixed voltage.

Power limited to motherboard header rating

The supplier notes that a typical 4-pin motherboard header supplies about 12 W, so the total draw of all attached fans must stay within that limit. The hub adds no active cooling or noise of its own. Exceeding the header's capacity can cause instability or shutdown.

Spurningar um þessa vöru

What does the 12 W figure mean when this hub is plugged into a motherboard 4-pin header?

A typical motherboard 4-pin header supplies about 12 W, so the hub lets you run multiple fans whose combined draw stays within that limit.

How does the PWM interface on this hub control fan speed in practice?

The hub passes the motherboard PWM signal to all connected 4-pin fans; 3-pin fans receive voltage only and cannot be speed-regulated.

What physical space and mounting does the 40 cm cable and 14 g hub need inside a case?

The 40 cm lead reaches most fan headers, and the 14 g hub has adhesive backing for securing it to a flat surface.
