The NF-A9 is a highly optimised, premium quality quiet 92mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance of the award-winning NF-B9. The FLX version provides 1600/1250/1050rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
Flow Acceleration Channels
The NF-A9 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
The NF-A9 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
Integrated anti-vibration pads
Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
Scope of delivery
Succeeding the NF-B9
Noctua's NF-B9 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 92mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A9 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.

The DS119 was VERY quiet.
In comparison the DS220+ is noticeably louder.
I'm using with SSDs so the only sound is the fan.
So I replaced it with the excellent Noctua NF-A9 FLX fan which is a real premium quality fan.
However on the default quiet fan mode setting in the DS220+ control panel the fan struggled to work. It would start off fine but eventually just stop moving.
This was true in the medium fan speed setting on the DS220+
However in the maximum fan speed setting it worked fine but was much noiser than the original fan set up!
The Noctua fan comes with two speed attenuator cables:
Low-Noise Adaptor (L.N.A.)
Ultra-Low-Noise Adaptor (U.L.N.A.)
I tried it with the low noise cable and it worked fine and was quieter.
I tried the Ultra low noise cable and that worked too and was super quiet.
I stuck with the ultra low noise cable and the DS220+ has been running for a day now with no fan issues and the temperature inside the case is nice and cool. Varies between 30 and 39 degrees.
In terms of noise the set up is marginally quieter than the Synology fan. The Synology fan had a very minor rattle. The Noctua is super smooth with no rattle.
Its not silent but its pretty quiet.
-Came with multiple adapters to choose from (To control the speed of the fan)
-I am running it at the lowest speed and the air flow is really good.
On top of that you will get 6 years warranty
The only downside is the color (and hopefully they will release a black version from this excellent fan)
I've purchased a few Noctua fans in the past and they are great quality products. This fan came with a nice selection of accessories, including some low noise adaptors, a 4 pin molex to 3 pin power adapter, a 30cm extension cable and some anti-vibration silicone mounts. I didn't need any of the extra accessories but it's a nice bonus and will make useful spares.
After fitting the fan into the NAS it's nearly silent now - I would go as far as to say it is quieter than it was from new! I can feel the air being pushed out the back so even though it's very quiet it's still providing excellent air flow.
This fan comes with a 6 year warranty which goes to show how much confidence Noctua have in their products.
The colour scheme is definitely not to everyone's tastes but as this fan is inside the NAS and not on show it's not a problem.
Beim Einsatz der Low-Noise Adapter (Im Lieferumfang) sollte die Lüftersteuerung in der NAS selbst auf volle Leistung stehen. Die Synology kann keine PWM Steuerung, sondern regelt die Lüfter per Spannungsanpassung.
Wenn dann z.B. die Synology bereits auf "leise" steht, werden die Lüfter mit weniger als 12V angesteuert, z.B. 7V. Wenn man dann noch einen der Low-Noise Adapter verwendet, kann es sein, dass der Lüfter zu langsam wird, oder stehen bleibt, und die NAS dann einen Lüfterausfall meldet.
Der Lüfter selbst macht einen guten Eindruckt. Der Lieferumfang ist umfassend. Verlängerungen, Adapter, Gummipuffer. Leider wieder mal viel zu viel unnützes Plastik als Verpackung genutzt.
Ansonsten ist der Lüfter super.
