USB Type-C PWM Fan Controller

The diymore A1_GBAA0052-002_US is a compact fan speed controller that draws power from a USB Type-C or USB Type-A port. It provides 5 V DC at up to 2 A for a single PWM fan, with speed set by a rotary knob that turns clockwise to increase speed and counter-clockwise to decrease or power off. The plastic housing measures 3.0988 cm x 8.9916 cm x 11.9888 cm and weighs 0.068 kilograms.

Makers and hobbyists adding variable cooling

This unit suits makers, hobbyists and anyone wanting stepless speed control for a 5 V PWM fan powered from a laptop, phone charger or power bank. The extendable cable socket allows flexible placement. Buyers who need to drive fans with a different voltage requirement or who require automated temperature-based control should look at other solutions.

5 V 2 A PWM output rating

The controller delivers a maximum of 5 V at 2 A (5 W) to the fan header, so the connected fan must be rated for 5 V operation and draw no more than 2 A. Exceeding this current limit will trip the built-in USB protection circuitry.

Questions about this item

How do I install the diymore A1_GBAA0052-002_US fan controller and what step is often missed?

Plug the controller into a USB Type-C or Type-A port supplying 5V 2A, connect the fan to the output socket, then turn the rotary knob clockwise to start; the step often missed is verifying the power source can deliver the full 2A rating.

What maintenance or replacement will the diymore A1_GBAA0052-002_US need later?

No scheduled maintenance is required; if the rotary knob or USB protection circuitry fails after extended use, the entire controller would need replacement.

What limit appears first on the diymore A1_GBAA0052-002_US during sustained use?

The 5V 2A (5W) power ceiling is the first limit; a fan drawing more than 2A will trigger the built-in protection and shut down the output.
