Review on 🔌 WINSINN 40mm Blower Fan 24V Dual Ball Bearing 4020 40x20mm Turbo Brushless - High Speed (Pack of 4Pcs) - Efficient Cooling Solution for Electronics and 3D Printers by Devin Tanner

Bought these fans to do a "fridge conversion on wheels". These things are very noisy when 12 volts are applied to them. I contacted the seller because one of the cases was broken and was told to initiate a Revain return for a replacement. I didn't have to worry about returning it as I really only needed one. When I say they're loud I'm not kidding, I hear this thing in the fridge with the door closed. As loud as it sounds, you'd think it would push out a ton of air, but that's only a so-so amount. I wouldn't recommend them for a mod I made and now I'm looking for something different.
