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 Ryan Cornelison

Used to cool my 3000w car amp. Works very well and has good airflow. It's a bit loud, but it was in my amp rack in my trunk, so I really couldn't hear it. Even at 149 dB(SPL) from 2 12 no problem. Without this fan, my amp (0.75 ohm load) would switch off after 1 hour. With fans, my amp didn't turn off at all due to the temperature. I connected the plus to the power supply of the amplifier (remote source) and the minus to the case.
