💡 How to pick case fans
What to look for:
  • 120mm most common, 140mm moves more air quieter
  • Higher CFM = more airflow, higher dBA = more noise
  • Static pressure fans for radiators, airflow fans for cases
💰 Two intake + one exhaust is a solid baseline for positive pressure

★★★★★Noctua is the best for a reason
Noctua is the best for a reason, quiet, and the best at moving air. Needed a usb option for a mini rack build and this is the perfect solution! Highest quality! You get what you pay for when it comes to these fans.

★★★★★Great fan if you pair with a speed controller.
Used this to upgrade a lesser quality fan in a cabinet to cut down on noise. If you want it silent, you will need something to adjust speed: Some RPM's are quieter than others and it's not linear. Definitely moves lots of air silently when tuned to the right speed.

★★★★★Good fan
Still running great non-stop years later. Not too loud but not very quiet as one can expect.

★★★★★Silent fan moves air.
Moves air and is silent just what I was looking for. Installed in power supply for a antminer.
