PWM Temperature Control Support The red interface can read fan speed, while the black interface supports PWM temperature control. Although it cannot read fan speed, case fan hub adapter provides efficient temperature control functionality. Convenient installation with Magnetic Design The fan controller hub splitter includes a bottom magnetic iron piece for easy and secure attachment to the metal plate of your computer case. Dual Power Interface Design The stable power interface of the PC RGB fan cooler ensures continuous and reliable output, even during fullload operation. Multiple Interfaces for Enhanced Compatibility With multiple interfaces, our ARGB and PWM hub allows you to connect and use more products simultaneously, expanding your options. Use scenarios Scenario 1: Upgrade an existing PC with ARGB lighting and PWM cooling by mounting the hub inside the case using the magnetic design, then connect multiple fans and lighting strips for synchronized control. Scenario 2: Build a compact or spaceconstrained setup where you need to power several fans and ARGB devices from a single hub, benefiting from the hub's multiple interfaces and stable dual power supply. Scenario 3: Create a load gaming or workstation rig that requires reliable cooling and lighting control; use the PWM control and tach reading where available to manage temperatures while maintaining consistent lighting effects.
