Review on 🌀 120mm x 25mm 5V USB Power Cooling Case Fan for Wathai Receiver DVR Xbox TV Box Router by Ario Rojas

I liked that when I placed it on my T-Mobile/Nokia 5G internet gateway at home, it felt hot from idle and got cool even under load. I used a USB-A to USB-C adapter to power the fan from the modem itself. The modem hasn't hung since I installed it above. I chose to place it on top because the legs prevent it from sliding down and drawing cold air through the open floor.
