PWM Fan Splitter Hub 1-to-10

The RIITOP PWM10-D expands a single motherboard PWM header into ten fan connections. It is built for enthusiasts who need to run multiple chassis or radiator fans from one control point. The hub includes a self-adhesive pad for tidy mounting inside the case. A 40 cm lead connects the hub to the motherboard header.

Molex Powered Expansion

The CPU fan header draws power and the speed signal from the motherboard, while the remaining nine ports are supplied by a Molex LP4 connector from the power supply. This layout lets the board monitor one fan and regulate PWM duty cycle for all attached 4-pin fans. Builders moving from a basic two-way splitter gain the ability to run up to ten fans without adding controller software.

Compatibility and Header Limits

Verify that your motherboard offers a standard 4-pin PWM header and that your power supply provides a free Molex LP4 lead. Only the red CPU port reports RPM back to the board; the other nine ports send PWM signals but return no speed data. Three-pin fans will run at full constant speed on any port because they lack PWM control. Ensure the 70 x 47 x 17 mm hub fits your chosen mounting spot.

Questions about this item

What are the hub dimensions and cable length for fitting inside a case?

The hub measures 70 by 47 by 17 mm and the included PWM cable is 40 cm (15.7 inch) long.

How do I connect the splitter to the motherboard and power supply?

Plug the 4-pin PWM lead into the motherboard CPU fan header and the Molex LP4 connector into a PSU Molex cable; the red CPU fan port gets speed monitoring, the other nine ports share PWM control.

Which fans will run at full speed and which support PWM control?

Only the fan on the red CPU port reports speed; the other nine ports provide PWM signals but no speed feedback, so 3-pin fans on those ports run at full speed while 4-pin fans obey PWM curves.
