Mauknci 12cm Quiet Cooling Fan with Adjustable USB for Small and More Airflow, 5V, Long-Lasting Operation, PCs, Amplifiers, Routers,

[Please note: The fan guard must be installed with the bulge facing outward for the fan to function properly!] Place your electronic device on the USB cooling fan and let the air flow from underneath it to cool it. This accelerates airflow and expels hot air, preventing heat buildup. The ultra-quiet design allows you to cool down a variety of electronic devices, including wireless routers, AV amplifiers, and smartphones while they are charging. The three speed settings allow you to adjust the airflow depending on your environment and the type of object you are using it for. Since noise levels are related to the speed, the weak wind mode makes it extremely quiet. Four metal feet keep the USB fan 27mm above the surface to ensure sufficient airflow, and vibration-absorbing rubber pads reduce noise caused by vibration. Dual ball bearings ensure stable rotation of the blades and reduce fan vibration. With a rated life of approximately 60,000 hours, it can operate 24 hours a day. Product Features 1.
