"Overheating" is eliminated by an elementary fastening (on top of the antenna, and from below - by simply placing it on outgoing "cables") on the back cover of the case fan. I use "Noctua NF-F12 5V PWM 120mm 1500 RPM NF-F12-5V-PWM" - it comes with a USB power adapter. Overheating (router) and much noise from the fan is not noticed. After reviewing a large amount of information on the Internet, I concluded that this is the most balanced device in its price segment at the moment. The purchase is completely satisfied. I can safely recommend to purchase.
