One-to-four PWM fan hub for multi-fan builds
The EN-Labs 11-001-245 expands a single motherboard PWM header into four fan connections using a 30 cm black-sleeved cable. It targets PC builders who need to run several case or CPU coolers from one header without adding a separate controller. The hub includes a self-adhesive backing so the small PCB can be secured out of sight inside the chassis. Power is drawn from a standard Molex connector supplying 12 VDC.
PWM control limited to one speed signal per header
All four fans receive the same PWM duty cycle, so they spin at identical speeds when four-pin models are attached. Three-pin fans connected to the three case-fan ports run at full voltage continuously because they lack PWM input. Only the dedicated CPU-fan port passes a tachometer signal back to the motherboard; the other three ports do not report RPM, so monitoring software will show a reading for just one fan.
Replaces daisy-chained splitters
Builders who previously used multiple Y-cables or a standalone hub can consolidate wiring with this single 1-to-4 assembly. The upgrade is worthwhile when cable routing space is tight and uniform speed across all fans is acceptable. It does not suit setups that require independent speed curves per fan or RPM feedback from every connected cooler.

| Features | It is designed for enthusiasts with need for controlling numerous system fans Capable of expanding one motherboard PWM fan header to support up to four fans. Support PWM Funciton, Speed control, satisfy your control needs. Compatible with 3-pin / 4-pin Fans Support Cable Management Comes with Self-Stick for easy installation and options to hide the PCB itself. Since only one RPM signal can be read by one motherboard connector, only ' CPU Fan' channel of the PWM splitter carries an RPM signal; thus the motherboard will only read the RPM signal of the PWM device that is connected to ch |
Questions about this item
Should I choose the 30 cm length or a longer cable for my case?
The 30 cm length suits most mid-tower builds; measure from your motherboard header to the furthest fan to confirm reach.
How does the single RPM signal affect fan monitoring?
Only the CPU fan channel passes a tachometer signal, so the motherboard reads RPM from the fan plugged into that port while the other three run at the same PWM duty cycle.
What does the 4-pin PWM header cap in practice?
One motherboard 4-pin PWM header powers and controls up to four fans simultaneously, with 3-pin fans running at full voltage.
