  Noctua :)

  Noctua NF-A4X20 PWN bought in 2 copies to ventilate my Nas in rack which was struggling with the +40°c daily.
  Without using the accessories supplied with these fans, I fitted them instead of the original ones as they were...
  The result is a lot more ventilation for a silence, which when they are full, is inferior to those of origin when they were at rest.
  In short: Noctua is very good and the brown/beige colour is as gratifying on a NAS as Ferrari red on an Italian car.

  Excellent products.

  I am impressed by the near-zero noise level of these two fans in operation, even when they are at maximum speed, even with the switch cover open. I am convinced of their performance and highly recommend them. However, their reliability can only be confirmed in the long term.

  Hello, is anyone there?

  Installed in a 1U short depth cpu Atom 3558 server.
  Extremely quiet fan! It remains to be seen if the performance will be good too. After a few hours, everything is ok in "full speed" mode (5100RPM according to the sensors), hence the half star on hold.
  To be recommended!

  super quiet

  The NOCTUA NF-A4X20 PWM is really quiet.
  Use as a replacement for a very noisy switch fan

  impeccable

  It's exactly what I need: good airflow, (for their size..), not much space available, but just enough for those, (2 side by side) and not noisy. I gain 5-6 degrees at the processor level in an SFF case; where the air circulates badly, and where the processor fan would collect too hot air....

  A bit noisy

  Everything is perfect except the noise. There is a small rattling noise which makes the fan louder than my NF-A12x25 ...
