Power adapter for three fans

This 20 cm cable splits a single Molex 4-pin LP4 connector from the power supply into three 3-pin fan headers. It is intended for builders who want to run multiple 12 V DC fans from one PSU output without occupying extra motherboard fan headers.

PWM sharing and RPM reporting limits

The splitter passes the PWM control signal to all three fans so they spin together, but only the header wired with four pins returns a tachometer signal to the motherboard. Consequently the board monitors the speed of just one fan while the other two follow the same duty cycle without independent feedback.

Single 4-pin header for RPM monitoring

Only the connector that retains all four pins delivers an RPM reading back to the motherboard; the remaining two headers lack the sense wire. This design prevents conflicting speed reports and suits setups where one representative fan is sufficient for thermal control.

Questions about this item

Should I use this splitter if I need all three fans to report their speeds to the motherboard?

Only the fan plugged into the full 4-pin connector sends a tachometer signal; the other two 3-pin connectors lack the sense pin so the motherboard reads just one RPM value.

What does the 12 V label mean for the fans I connect?

The cable draws 12 V DC from a Molex LP4 connector, so every attached fan must be a 12 V model — 5 V fans cannot be used.

How does the Molex LP4 connector limit the power available to the three fans?

The single 5.25" Molex 4-pin plug supplies all current, so the combined draw of the three fans must stay within what that one PSU lead can deliver.
