GELRHONR PC Fan Controller 12V 4Pin PWM USB C 4 Way Splitter Hub 8WThis PWM fan controller is designed for PC enthusiasts who need flexible cooling solutions. It draws power from any USB-C port and uses a built-in voltage booster to convert the 5V input into a stable 12V output for standard 4-pin PWM fans. The controller supports manual speed adjustment via a front knob or automatic PWM control that responds to system load, providing near-silent operation during light tasks and increased airflow when needed. A 4-way fan splitter hub lets you connect multiple fans simultaneously, making it ideal for small PC builds, routers, and custom DIY cooling projects. Maximum power output reaches 8 watts when paired with a 5V/2A power adapter.Itemweight0.15 poundsProductdimensions3.3 x 1.1 x 4.9 inchesPartnumberLH-923Manufacturer
