Sleeved SATA Power to 3x 4-pin TX4 PWM Splitter Fan Power Adapter Converter Cable with one 4in Female Header to Mohterboard for RPM Feedback & PWM Fan Speed Control - 16.9 inch

SATA to 4-pin PWM Fan Power Splitter Adapter Converter Cable gives you a simple, cost-effective way to connect multiple computer case fans to a single motherboard fan header.
The black sleeved jacket not only enhances cable management, but also provides a sleeker look that seamlessly integrates into the interior of any case.
The SATA3TX443CM features one 15-pin SATA male connector at one end for connection to your computer PSU, and offers three TX4 male connectors and one TX4 female connector at the other end, which allows for easy connection up to three PWM fans at the same time.
For PWM Function
The TX4 female header must connect to your motherboard, for sending the RPM signal to the motherboard and PWM controlling, allowing all fan speed to be synchronized with CPU load.
Only one of the three fans sends its tach signal (the one with full TX4 4-pin tips) and reports its RPM, but the others will still follow the PWM signal. Two of Three male TX4 connectors are missing the pins of tachometric signal, ensuring your fan speed monitor won't bounce all over the place from getting three sense signals. You motherboard can always get an accurate RPM signal.
Note:

1. Power from PSU 12V DC only; do not utilize for 5V DC fan

2. The TX4 4-pin male connectors are compatible with both 4-pin PMW fan connector and 3-pin fan connector.

3. Only one TX4 female header have full 4 tips. please make sure this special header connect fan priority
