Review on 🌀 UTUO Brushless Centrifugal Blower: High Speed 24V DC Dual Ball Bearings Fan - 120mm x 32mm (4.72x4.72x1.26 inch) with XH-2.5 Plug by Gregory Flynt

It's 12V, draws only about 1.2A (if you let it). Reverse polarity does not change the direction of rotation, it just prevents it from working. I use it to remove heat from a 2kW inverter. In a barn with a temperature of 43 degrees Celsius, the outside temperature of the converter dropped from 41 degrees Celsius to 34 degrees Celsius in 10 minutes. table like a turbine. This is HIT HARD! It's loud, that's for sure, BUT if you need real air movement and cooling performance, this is a really good choice!
