Feature:1. Low Noise Operation: The case fan absorbs high speed vibrations and produces a maximum noise level of only 24.9dBA, equivalent to the sound of falling leaves, ensuring an undisturbed work or gaming environment.2. Efficient Dual Ball Bearing: The cooling fan features highly reliable dual ball bearings, capable of withstanding high temperatures and providing a lifespan of over 40,000 hours, perfect for 24h continuous use.3. PWM Intelligent Temperature Control: Equipped with a 4 pin PWM interface, the computer case fan can adjust its speed according to the operating environment, reaching speeds of up to 3000rpm while reducing noise levels.4. 7 Blade Design: With 7 high pressure fan blades, the case fan delivers a maximum airflow of 12.7CFM at 3000PRM, focusing on enhancing performance by offering stable wind pressure and strong airflow.5. Easy Installation: The cooling fan is compatible with all types of computer cases and features a user friendly power interface design, making it easy to install. With 50mm screw hole spacing. (Hole spacing is the distance between the centers of the two screw holes.)Specification:Item Type: Case FanMaterial: PBTColor: BlackFan Size: Approx. 60x60x15mm/2.36x2.36x0.59inBearing Type: Dual BallRated Voltage: 12VRated Current: 0.03A10%Rated Speed: 3000RPM10%Airflow: 12.7CFM10%Noise Level: 24.9dBA10%Interface: 4 Pin PWM.Package List:1 x Case Fan4 x Screws
