Product identity

The EN-Labs PRPWMHUB5 is a 5-port PWM fan hub that expands a single motherboard 4-pin header into five 4-pin connectors. It includes a 1.3 ft PWM extension cable and five solid capacitors to stabilise power drawn from the CPU_FAN or SYS_FAN header. The hub is designed for builders who want to run multiple 12 V fans from one PWM source.

Setup check

Verify that your motherboard has a spare 4-pin PWM header rated to supply the combined current of all attached fans. The red connector is intended for the CPU fan signal; 3-pin and 2-pin fans will run at full speed because they cannot accept PWM control. The 3M double-sided tape on the back requires a clean, flat surface for secure mounting inside the case.

Thermals noise power

The hub itself adds no active cooling and draws negligible power beyond the fans connected to it. Fan speed and noise are governed entirely by the motherboard PWM curve applied to the CPU_FAN or SYS_FAN header. The onboard capacitors help smooth voltage delivery, reducing electrical noise on the header without affecting thermal performance.

Questions about this item

What cables and connectors come with the EN-Labs PRPWMHUB5 hub?

The package includes the 5-port PWM hub board with one 4-pin female input and five 4-pin male outputs, plus a separate 1.3 ft 4-pin PWM extension cable with a latch-locking connector. The hub’s back has 3M double-sided tape for mounting.

Should I choose this 5-port hub or look for a different capacity?

This model provides exactly five 4-pin fan headers from a single motherboard 4-pin header. If you need to run more than five fans from one header you would need a hub with additional ports; if you need fewer ports a smaller splitter would suffice.

What does the 12 V rating mean when the hub is installed in my PC?

The hub draws 12 V power from the motherboard’s CPU_Fan or SYS_Fan header and distributes it to all connected fans. Four-pin PWM fans receive speed control; 2-pin or 3-pin fans run at full speed because they lack the PWM signal wire.
