Review on 🔧 Coolerguys 12v Ultra Quiet Fan: Ideal for Pi Devices, 3D Printers, and Microelectronics (40x20mm) by Eric Jones

There is a trade-off between airflow and noise. Unfortunately, for fans of this size, you just can't have both. You can tell if the fan will be strong or quiet, but by rating the amp. My previous one was at 0.4A, relatively strong and noisy. But this one is at 0.16A, with less flow but much quieter. It is significantly quieter than the previous fan (in the power supply). And luckily I didn't need a stronger fan. You can still hear that new fan. I can best describe the volume as the low hum of an average refrigerator. Hope this lasts long.
