Metal Case for Raspberry Pi 4B (Dual fans)

This is a top - notch metal case from DFRobot designed specifically for the Raspberry Pi 4B. It comes equipped with two fans to keep your device cool. The fans start running as soon as the Raspberry Pi is powered on, though they aren't program - controlled. Made of high - quality aluminum alloy, it combines durability and lightness. The case measures 87 * 56 * 25 mm (3.4*2.2*1.0 inch) and weighs only 101g. Each fan operates at a voltage of 5V with an operating current of less than 150 mA.

Using this metal case for your Raspberry Pi 4B is easy. First, place your Raspberry Pi 4B into the case carefully. Make sure all the ports align well. Once it's powered on, the two fans will start running automatically to cool your device. Note that the fans are not program - controlled, so they'll stay on as long as the Raspberry Pi is powered. For maintenance, keep the case in a clean and dry environment. You can use a soft, dry cloth to wipe the exterior of the case occasionally. Avoid using any harsh chemicals that might damage the aluminum alloy material. If the fans seem to be making unusual noises, check for any dust or debris around them and clean gently with a small brush.
