Review on 🌬️ High-Performance PLUSPOE 40mm x 10mm Brushless Cooling Fan - Ideal for Computer Cases, 3D Printers, Humidifiers, and Small Appliances Repair/Replacement by Hugh Starr

They fit Ender 3. They seem to flow as much as the original Creality brand. At first they are calm. Much quieter. Unfortunately, a small dent on the fan blades and it's over. I was testing the motor and accidentally hit the blades with a screwdriver and it got loud. There was nothing I could do to shut him up again. It's ok I bought two but hit the blades again now I'm back to the noisy fan. Still better than stock but nothing like the youtube video. The case also adds sound to the system. Overall it's a bit quieter, with less high-pitched rumble, to be honest that's my biggest complaint.
