Review on SOTOP IP55 Waterproof Metal Blades Axial Fan, 115V AC 120mm x 38mm High Speed for Enhanced DIY Cooling, Ventilation, and Exhaust Projects by Todd Atherton

I have two of these to aerate my indoor garden. They are connected to a timer that turns them on for 15 minutes every hour. They provide good airflow and I love that they are waterproof because I spray my plants almost every night. They're a bit loud, but not too loud. It can be annoying when they are always on and you are in the same room. My only minor complaint is the power cord. The cable connects to the fan via a non-standard connection and the cable is quite short. I had to hang the surge protector on the wall to get the power cord. Not a big deal, but something to consider if your PSU is far from the fan.
