I need some advice about replacing the fans of a Synology DS412+. I know that Synology says it is very quiet but that is very far form the thruth, unfortunately. Fans can easily be heard from 3 meter distance, so very much above the 20DB they say!
This NAS comes with 2 fan 92mm: Y.S. Tech, model number FD129225LL-N (12V, 0.12A, 1900RPM, 36.3CFM). However I cannot find any test of this fans so I don't know how much the officall specs are to be trusted. Likewise it seems there have not been any 92 mm fans test here in a long time, and therefore I need to rely onto anybody who has had some recent experience with 92mm. Any suggestions on really really quite 92mms fans?
Alternatively I would have to do some heavy modding to fit 2 120mm fans. Long time ago I used in a PC an asymmetric 92 to 120 adapter, which could eventually be a solution (not pretty but workable) to this problem, but also I don't seem to find it anymore as probably is our of production.
For at look at how this NAS looks outsinde and inside look here: http://www.techpowerup.com/reviews/Syno ... lus/1.html
Any suggestion and advice would be greatly appreciated.
