Review on 🌀 12V Brushless DC Cooling Fan - GDSTIME 80mm x 80mm x 25mm by Keith Barra

Mounts with rubber bands (to isolate vibration) in a Faraday cage around the Wi-Fi router to keep the router cool. The inlet side of the fan is not protected by the case, there is minimal protection at the outlet. A metal grille is supplied with the fasteners. There is some air movement noise, but the fan itself is very quiet and powerful enough. I cut off the plug and connected it to a 12V 2A adapter controlled by a digital thermostat.
