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

Great little fan. I use it as an exhaust fan in my bedroom. I keep my house pressurized so the air naturally wants out, but the wind can make the situation unsafe and I need constant ventilation. So I open the window and block the hole with this directional fan and even with a decent headwind the air keeps coming out. However, it doesn't move much air. But it moves a little, that's all I was looking for, a slow but steady stream of exhaust. If you want more than a trickle, use a more powerful and louder fan. But if staying quiet about airflow rate is your priority, this fan makes little to no noise. He has excellent speed control. It's plug and play. A big fan all around.
