Ruth's sister 5 Port Fan Hub Splitter PWM

SKU CH-P3JM-501HW

Connects five 4-pin PWM fans to a single motherboard header for centralised speed control

  • Connect five PWM fans from a single header
  • Control all fan speeds together via PWM signal
  • Power fans directly through 5 dedicated 4-pin connectors
  • Simplify cable routing inside the case

5-Port PWM Fan Hub Splitter

This internal power cable splits a single motherboard 4-pin PWM header into five fan connections. It is designed for PC builders who need to run multiple cooling fans from one speed-controlled source. The adapter handles the PWM signal so all attached fans respond together to the motherboard curve.

PWM speed control limitation

The hub passes one PWM signal to every port, so all five fans must share the same speed profile. Builders who require independent speed curves for each fan cannot use this splitter. It also draws combined fan power through the single motherboard header, which has a current limit.

Questions about this item

How does the 5-port hub let the motherboard control fan speeds?

The fourth pin on each 4-pin connector passes the motherboard's PWM signal to every attached fan, so the board can run automatic speed curves across all five fans simultaneously.

What limits the number of fans I can safely run from the single motherboard header?

The motherboard header's current rating caps the total draw; the hub simply splits the PWM signal, so the combined fan amperage must stay within that header's limit.
