This tiny 30mm fan is designed to plug right into the GPIO header on a Raspberry Pi. The ability for air to cool an object is directly dependent on the temperature of the air itself. Being able to move fresh cool air over a high heat component like the Raspberry Pi’s processor will dramatically lower the temperature and help prevent it from throttling under high load. The fan measures 30 x 30mm and just 10mm thick. It operates on 5VDC and features two female “Dupont” connectors on the end.
