4-Port PWM Fan Hub with Dual Knobs

The LORDWORLD hub connects four 12V 4-pin PWM fans to a single controller. Two independent knobs each manage a pair of fans, allowing separate speed profiles for different cooling zones. Power comes from either a SATA connector or a DC 5521 jack, delivering up to 100W. A full-height PCI bracket mounts the unit inside the case.

Builders who want hardware fan control without

Suits desktop, NAS and server builds that lack enough motherboard fan headers. The pure hardware PWM circuit needs no drivers and runs continuously. Not for systems using 2-pin or 3-pin fans, because the headers accept only 4-pin PWM connectors. Users who prefer automatic temperature curves should look at motherboard-controlled headers instead.

Installs in a free PCI slot

The bracket occupies one rear expansion slot, keeping cables inside the chassis. Only one power source — SATA or DC 5521 — must be connected at a time. Four onboard headers accept standard 4-pin fans, and splitters can be added to run more fans per channel. This leaves motherboard headers free for CPU or GPU cooling.

Questions about this item

Do I need standard 12V 4-pin PWM fans for this hub to work?

Yes, the hub only supports standard 12V 4-pin PC cooling fans; 2-pin or 3-pin fans are not compatible.

Can I power the hub from both a SATA connector and the DC 5521 jack at the same time?

No, you must use only one power source at a time; connecting both simultaneously is not supported.

How can I verify the PWM speed control is functioning after installation?

Turn each knob and confirm the two fans assigned to that knob change speed smoothly and quietly without software.
