Review on 💨 120mm USB Fan - Speed Controller Cooling for Tablets, TV Receivers, Routers, DVRs, Playstations, Xbox and Computers by Marcus Freeman

My TP-Link router sometimes fails due to overheating. Since it has a USB port (for file sharing, which I don't use), I bought this fan and installed it on the back of my router. After installation it started quite well. Not a single failure for over 10 days. The fan isn't "completely silent", but it's quiet enough to be unnoticeable. For the price I think it's a good addition. I can get another one for my wifi extender.
