PWM Fan Splitter Cable Hub 1 to 4 Power Adpater,Motherboard PMW 4-pin Fan Sleeved Braided Y Splitter Internal Power Extension Cable for Computer CPU/Case Fan 1x4 Converter - 10 inches

Features
This TX4 4-pin multi-fan splitter cable connects to your motherboard and controls three PWM fans.
Since only one RPM signal can be read by one motherboard connector, only one 4 TIPS CONNECTOR of the fan splitter cable carries an RPM signal; thus the motherboard will only read the RPM signal of the PWM device that is connected to full 4-pin connector.
The other three male connectors are missing the pins of tachometric signal, ensure your fan speed monitor won't bounce all over the place from getting three sense signals. Guarantee motherboard getting an accurate RPM signal.
Only one of the three fans sends its tach signal (the one with full 4-pin connector) reports its RPM, but the others will still follow the PWM signal.
Compatible with 4pin PMW fan connector and 3pin fan connector
Sleeved in a black is enhanced cable management, enclosure to provide a sleeker look that seamlessly integrates into the case's interior

Note:

Only the fan on 4-pins connector is used for monitoring.
All connected fans are following the same PWM signa, speed control is the same for all fans when use fan controller software like AI stuite/Xspert FAN and EASY TUNE, etc
PWM capable connectors must necessarily be 4-pin, but not all 4-pin motherboard connectors implement or enable the PWM signal modulation by default. Please carefully consult your motherboard documentation in this respect.
