Review on 🌀 UTUO Brushless Radial Blower: High Speed 12V DC Centrifugal Fan - Dual Ball Bearing, XH-2.5 Plug, 120mm x 120mm x 32mm (4.72x4.72x1.26 inch) by Tim Ram

I bought this fan to cool the generator in the engine room of my sailing boat! The compact form factor was important to me and it fit perfectly in the small space I needed for the installation. It moves a lot of air - about 45 cfm, which might not sound like a lot, but it's actually quite a lot, and it does its job fairly quietly, unlike some other fans I've researched that sounded bigger than jet engines. Before installing this fan, my alternator was getting hot. up to >400F! Now it barely goes above 280F and all I did was put that fan about 20 inches behind it. If you need to cool something and don't want a lot of noise, this fan is a very good choice.
