PWM fan controller for six fans

The OwlTree PC042 is a 4-pin 12V PWM fan controller that supports up to six fans from a single hub. It draws power through either a SATA connector or a DC 5.5×2.5 mm jack and provides a combined 60 W at 5 A. A manual knob adjusts the PWM duty cycle from 1 % to 99 %. The unit is built from black plastic and weighs 0.06 kg.

Suits builders with multiple 4-pin fans

This controller is for system builders who need to run up to six 4-pin PWM fans from one power source and prefer a physical speed dial. It is not for users with 3-pin or 2-pin fans, because the headers are not compatible. Buyers who want software or motherboard-based fan curves should look at something else. The package contains only the controller; fans and cables are not included.

Handles six fans within a 60 W limit

Each of the six ports can deliver up to 2 A, but the total current must stay at or below 5 A, giving a 60 W ceiling at 12 V. That headroom comfortably covers several typical case fans running together. If the combined draw of all connected fans exceeds 5 A the controller will not provide enough power. No higher-capacity option is offered in this model.

Questions about this item

What power connections do I need on my power supply to run this controller?

The unit accepts either a SATA 12 V connector or a DC 5.5×2.5 mm (5525) 12 V plug, so you need one of those free on your PSU or an appropriate adapter.

Will my existing 3-pin case fans work with the six 4-pin headers on this hub?

No, the controller only supports 4-pin PWM fans; 3-pin or 2-pin fans are not compatible with its six ports.

How can I confirm the PWM signal is actually reaching each fan after I wire everything up?

Turn the speed knob and watch the LED indicator; the fans should spin from a low 1 % duty cycle up to 99 %, proving the PWM signal is active on every connected port.
