PWM fan splitter for four fans

This EN-Labs PWM1X4SPL10IN cable splits a single motherboard 4-pin header into four fan connections. It is designed for builders who want to run multiple PWM fans from one header without adding a controller. The 10-inch length suits compact routing inside typical cases. It does not suit builders who need independent speed curves for each fan.

Straightforward install with one monitoring limit

Plug the female end into the motherboard header and attach up to four fans to the male connectors. Only one male connector carries the full 4-pin tachometric wire so the board reads a single RPM signal; the other three connectors omit that pin to prevent signal conflicts. Compatible with both 4-pin PWM and 3-pin voltage-controlled fans. The braided sleeve eases cable management but adds slight stiffness in tight bends.

Steady PWM control across all connected fans

All four fans follow the identical PWM duty cycle sent by the motherboard, so speeds rise and fall together under sustained load. The single reported RPM reflects only the fan on the full 4-pin connector, while the remaining fans track the same signal without individual monitoring. The 12 VDC rating matches standard fan headers for continuous operation.

FeaturesThis 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.

Questions about this item

How do I confirm the splitter is controlling all four fans correctly after connecting it to the motherboard?

Connect the fan with the full 4-pin connector first; the motherboard will read its RPM while the other three fans follow the same PWM signal and spin at identical speed.

What does the 10-inch cable include and are any extra cables or adapters required?

The box contains one 1-to-4 PWM splitter with a 4-pin female motherboard connector and four male fan connectors; no additional cables or adapters are needed for standard 4-pin or 3-pin fans.

Which connector should I use for the fan I want the motherboard to monitor?

Use the single full 4-pin male connector for the fan whose RPM you want reported; the other three 3-wire connectors omit the tach pin so only that fan's speed is monitored.
