4 Pin 1 Female to 2 Male Y Splitter PWM Fan Power Converter Adapter Cable

4 Pin 1 Female to 2 Male Y Splitter PWM Fan Power Converter Adapter Cable for PC Computer

1. PWM 4-pin fan “Y” cable connects to your motherboard and controls two PWM fans.

2. 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.

3. The other 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.

4. Only one of the two fans sends its tach signal (the one with full 4-pin connector) reports its RPM, but the others will still follow the PWM signal.

5. Compatible with 4-pin PMW fan connector and 3-pin fan connector (Due 3-pin no PWM controller, 3-pin fans would run in full speed.)

Compatibility with: Master Fan: 4-pin Male Slave Fan: 3-pin Male Motherboard PWM: 4-pin Female Notes: 1. 3-pin or 4-pin fan compatible. 2. Motherboard must be able to power 2 fans. 3. All connected fans are following the same PWM signa, speed control is the same for all fans when use fan controller software. 4. PWM capable connectors must necessarily be 4-pin, but not all 4-pin motherboard connectors implement or enable the PWM signal modulation by default. 5. Please carefully consult your motherboard documentation in this respect.
