LORDWORLD USB-C 5V to 12V 4-Pin PWM Fan Controller 8W

SKU CH-V2VH-BB923

Converts a USB-C 5 V supply into a 12 V PWM signal for 4-pin fans up to 8 W

  • Powers 12 V PWM fans from any USB-C 5 V source
  • Boosts 5 V to 12 V with on-board DC-DC converter
  • Delivers up to 8 W for low-power cooling builds
  • Four-pin PWM output enables precise speed control
  • Open-board design lets you 3-D-print a custom enclosure

USB-C 5V to 12V PWM fan controller

This compact board converts a USB-C 5 V supply into a 12 V PWM signal for four‑pin fans. It is aimed at hobbyists and DIY builders who want to run a low‑power cooling fan from a standard USB charger or power bank. The device includes a built‑in boost circuit and requires no soldering for basic use.

8 W maximum output with charger‑dependent headroom

The controller can deliver up to 8 W to a compatible 12 V PWM fan, but actual headroom depends entirely on the 5 V source used. A charger that cannot supply enough current will limit fan speed before the board’s own rating is reached. It cannot drive 3‑pin or 2‑pin fans at all.

Four‑pin PWM‑only output socket

The single deciding specification is the 4‑pin PWM output, which means the board only works with fans that accept PWM speed control on a fourth wire. Builders needing voltage‑controlled 3‑pin fans or simple 2‑pin fans must choose a different solution.

Questions about this item

Will this controller run a 4-pin PWM fan from an older USB-C charger?

Yes, the TYPE-C female input accepts 5 V from any USB-C charger, and the built-in boost circuit converts it to 12 V for the 4-pin PWM fan socket.

How can I confirm the fan speed is being regulated correctly?

Connect a 4-pin PWM fan, power the board from a USB-C source, and verify the fan responds to PWM duty-cycle changes; the tachometer wire on the 4-pin header reports RPM back to the controller.

Does the package include a fan, cables or an enclosure?

Only the controller board is supplied; you must provide a USB-C power source, a 4-pin PWM fan, and any 3D-printed or custom enclosure you wish to use.
