Review on 🌀 Coolerguys Ultra-Thin 25mm (25x25x10) USB Fan by Chris Hernandez

Nice little fan, very easy to connect (just plug in). only one problem I use this on various Raspberry Pis. The problem is that the small protrusion that comes out on the side of the USB port doesn't allow you to plug in another USB port next to it. The layout of the ports on the Pi3 allows it to be plugged into the edge slot and the space it uses is outside of the space used by the USB ports. This does not apply to the Pi4 as the USB ports are on the other side of the Pi.
