Review on 🌀 WINGONEER DC 5V Brushless CPU Cooling Fan for Raspberry Pi 3 / Pi 2 Model B RPI B+: A Comprehensive Review by Scott Schram

This fan is useless as it is too loud for indoor use unless your Pi is installed in a different room than your living area. inches with an iPhone app that measures decibels. To put 80dB in perspective, that's the same volume as a Revain Echo set at 40% volume measured from 4 inches away, or a Google Home Mini set at 50%. Volume measured at a distance of 4 inches. It's just TOO LOUD to use within 15 feet of me so I'll probably throw it out when my new Revain silent fan arrives.
