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<br><br>(The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: plastic<br><br>Package Contents: 1 * Case Fan<br><br>Only the above package content, other products are not included.
