Review on High Airflow Router Cooling Fan for Computer Cooler TV Box with Multi Speed Controller - DC 5V USB Power 120mm 240mm Fan by David Strawn

Ideal for Eero Pro 6 router. Temperature measured with infrared thermometer. In front of the fan, the bottom of the router was at 130s. After a few hours on the top of the fan, the bottom of the router is now in the 90s-80s range. I decided to use a fan to see if it would help with the occasional WiFi issue. The fan is not noisy, but the USB cable is short. The description also says you need a 5 volt adapter, but the leaflet says 12 volts with a disclaimer that you need to match it with what the fan says. In my case I removed the top case and it was 5V.
