6-Port PWM Fan Controller Hub

The AJMRTC AJ*FAN*CTL06 is a manual fan controller hub that manages up to six 12V 4-pin PWM cooling fans inside a desktop computer case. A large rotary knob provides stepless speed adjustment from 0 to 100 percent without any software installation. It is built for PC builders who want direct hardware control over chassis airflow and noise levels.

Dual SATA and DC 5525 Power Input

The hub accepts power from a standard SATA connector or an external DC 5525 barrel jack, delivering a maximum total output of 5A at 60W. This dual-input design removes the load from motherboard fan headers when running multiple fans. Upgrade from a basic splitter when you need higher combined current capacity and independent speed control for all connected fans.

DIY Builders Needing Manual Multi-Fan Control

This unit suits enthusiasts building gaming PCs, workstations or water-cooling loops who prefer a tactile knob over software curves. It is not for users who require motherboard-reported RPM feedback or automatic temperature-based fan curves, as the manual controller does not return speed signals to the system BIOS.

Questions about this item

Does the hub need a SATA cable from the power supply or can it run from the DC 5525 jack alone?

The unit accepts either a SATA power connector from the PSU or an external DC 5525 barrel jack, and either source can deliver the full 12 V 5 A 60 W budget.

How do I connect the PWM fans so the knob actually controls their speed?

Plug each 4 pin PWM fan into one of the six 4 pin ports on the hub, then power the hub via SATA or DC 5525; the rotary knob then varies voltage to all connected fans from 0 to 100 %.

Will I need to replace the controller if a fan header stops working?

The hub has no user serviceable parts; if a port fails the whole unit would need to be swapped, but the solid PCB and protective housing are built for long term use inside the case.
