What this cable does

This PWM 4-pin splitter connects a single motherboard header to three fans. It delivers the same speed signal to all connected fans so they spin together. Only the fan plugged into the full 4-pin branch reports its RPM back to the board. The other two branches omit the tach wire to prevent conflicting signals. Three-pin fans attached to the cable will run at full speed without PWM control.

Check your motherboard header

Verify that your board offers a 4-pin PWM header for the splitter's female connector. The cable is 10 inches long, so measure the distance from that header to each fan mounting point. Confirm whether each fan uses a 4-pin or 3-pin plug, because 3-pin fans will ignore the PWM signal and run constantly at maximum speed. Ensure the single reporting fan is the one you want monitored in software.

Build and daily use

A black net jacket sleeves the wires for a tidy appearance inside the case. The 10-inch length keeps routing short between closely spaced fans and the motherboard. Because all fans follow one PWM curve, you adjust every connected cooler with a single software slider. Remember that only the fan on the full 4-pin branch feeds RPM data to the BIOS or monitoring tools.

FeaturesFeatures 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 two 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.

Questions about this item

Does the 10 inch cable include all connectors or must I buy extra plugs?

The 10 inch cable comes with one TX4 female connector and three TX3/TX4 male connectors, so no extra plugs are required.

Which of the three male connectors should I use if I want RPM monitoring?

Only the full 4-pin male connector passes a tachometric signal to the motherboard; the other two lack the sense pin and run at the same PWM duty cycle without reporting RPM.

What happens to 3-pin fans when they are attached to this splitter?

3-pin fans receive the same PWM voltage as the 4-pin fan but run at full speed because they lack PWM control logic.
