Best cooling technology: Designed for superior cooling performance. It features advanced aerodynamic design, such as airflow acceleration channels, for superior silent cooling Versatile interface: This fan is equipped with a 3-pin interface and supports PWM control, which can flexibly control the fan speed to the best balance between cooling effect and noise Small and powerful: The fan measures only 40x40x10 mm, which can perfectly fit into small spaces, making it ideal for compact cases or other small spaces that require efficient cooling Intelligent temperature control: This feature allows the fan to automatically adjust the speed according to the system temperature, achieving quiet operation without sacrificing performance (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: plastic Package Contents: 1 * Case Fan Only the above package content, other products are not included.
