Review on Coolerguys 40mm (40x40x20) High Airflow IP67 Waterproof 12V Small Fan by Dezz Watson

I had an 80mm in my orchid garden in my office and I really liked it so I went with the 40mm as it was would be easier to hide it in plants. . I had to listen to all the reviews mentioning how noisy it is. That's about 10 times louder than 80mm. I really couldn't concentrate when he was working. In terms of functionality, this is a powerful little fan that moves a lot of air. Decided to buy another 80mm.
