Review on 🌬️ Sunon KD0501PFB3-8 5V 2010 20x20x10mm Cooling Fan (2 Pack) - Small Mini Micro C12 by Harry Jenkins

I like it. I put two in the helmet of a suit I made and they allow for perfect airflow. The helmet was unbearable without them, but with a puff and a puff I could wear it for hours. The size is so small that I was able to hide their placement in the helmet's details, and they are incredibly quiet. them to a 9 volt battery with a resistor, and at the moment I have 6 hours.
