I am thinking to replace the fan of the RS819 by noctua fans to make it more silent. Is the NF A4x20 FLX ok? Or should I take the 5v modele? Does it worth the change?
yeah i may try it i am wondering if it will really help to reduce the noise...I like Noctua fans, I have them everywhere.
as I remember for some my recommendations for the single U cases from Synology, you need really heavy airflow, then silent fans. up to your common environment operation temperature.
But Noctua can do it in both way.
