Review on 🌀 Avanexpress Replacement Cooling Fan - AFB1212SHE High CFM, 120x38mm, 2Pin 2Wire, 12V DC by Chad Boho

These are incredibly powerful fans (with adjustable speed based on voltage). First I tried different fans to cool the server rack, but they just couldn't get enough air. On the other hand, they were amazing. They can be very loud at full speed, but I don't know of any other fan that moves the same amount of air and is quieter. (In fact, some other fans sound just as loud and move a lot less air.) I don't think I'd recommend them for a home PC unless you're deaf or don't mind sleeping with earplugs. . (I have mine in the garage, so all I hear is a slight hum inside.) But if you're cooling server racks, that's exactly what you want.
