Noctua The ULTIMATE Quiet Computer Fans

Computer fans can be loud. Anyone using a computer has, at one time or another, been annoyed by the buzz, whine or outright shriek of PC, CPU
and  cooling fans. Unfortunately, cooling is necessary, and even water-cooled computers use fans on their radiator. The key to a quiet computer fan
is twin-fold: pick the right fan and minimize the noise from your PC fan. Thanks to Noctua fans PC and CPU Cooling can be done Quiet Silent even
Noiseless. Read and learn how.

Today I would like to talk about Noctua Fans.

I was quiet intrigued by the name of the company when we I first found out about them for those of you who are as curious as I was it means ^ The
little owl, Athene noctua, is the symbol of the Greek goddess Athene, who represents wisdom, science and strategy.

Noctua offers a wide variety of products Like computer fans, CPU heatsinks, and chipset cooler but today I would like to focus on their fans. First of
lets get to know about the company them selves.

About Noctua
Noctua aims at establishing a new level of quality and performance “Designed in Austria” through paying attention to the users’ needs in a market
burdened with all kinds of frills and furbelows and providing sound-optimised premium components, which serve their purpose in a smart, precise
and reliable manner. Noctua’s sound-optimised premium CPU heatsinks and computer fans are designed using scientific measurement
instrumentation, methods of calculation and simulation technology, and meet the highest demands in terms of performance, quality and quietness
of operation.

It seems Noctua clearly aims at establishing a new level of quietness, quality and performance. There has been allot of R&D Research &
Development put into these quiet PC cooling products Noctua partnered up with the Austrian Institute for Heat-Transmission and Fan Technology
The development partnership between the ÖIWV and Noctua clearly shows how the enormous potential of Austrian research facilities and high-tech
companies can be implemented in market leading quality products with economic success.” Mag. Manfred Stadler MBA.



Now my evaluation of these computer fans.

The fan manufacture at this point only offers three fan selections two in the 120mm category and one in the 80mm category lets have a look at them
Now are evaluation of these computer fans. The fan manufacture at this point only offers three fan selection two in the 120mm category and one the
80mm category lets have a look at them.

The NF-S12 is the first fan employing a novel rotor which was developed by the Austrian Institute for Heat-transmission and Fan Technology
(Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV). Thanks to the special optimisation of the blade geometry towards
ultra low noise application, the NF-S12 is up to 10% more quiet than current high-end fans at the same flow rate.Self-stabilising oil-pressure
bearing (SSO bearing): The NF-S12 series are equipped with a magnetically centred, self lubricating oil-pressure bearing that provides a new level
of quietness and long-term stability.

Specs: 800 RPM 8 dB(A) @ 35 CFM

"SILENT." Impressive.


Now lets have a look at the specs of the more punchy 120mm model

The NF-S12 is the first fan employing a novel rotor which was developed by the Austrian Institute for Heat-Transmission and Fan Technology
(Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV). Thanks to the special optimisation of the blade geometry towards
ultra low noise application, the NF-S12 is up to 10% more quiet than current high-end fans at the same flow rate.Self-stabilising oil-pressure

Specs: 1200 RPM17 dB(A) @ 48 CFM

Size 120×120x25 mm Bearing SSO-Bearing Blade Geometry Straight-Blade-Design Rotational Speed (+/- 10%) 1200 RPM. And now the 80mm
Model The NF-R8 is the first fan employing a novel 80mm rotor which was developed by the Austrian Institute for Heat-Transmission and Fan
Technology (Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV). Thanks to the special optimisation of the blade

"VERY QUIET." Yet it packs a punch.


Finally Let's evaluate the 80mm quiet computer fan.

The NF-R8 series are equipped with a magnetically centred, self lubricating oil-pressure bearing that provides a new level of quietness and long-
term stability.

Specs: 1800 RPM 17 dB(A) @ 22 CFM

Im "Amazed.". All i can say Noctua has re-invented the wheel here...

Here is what I have to say about these "Amazing" very quiet computer fans. In my opinion this is most quiet computer fan Ive gotten my hands on to
this date. The first fan I received I held in my hand and it was inaudible to my ears and when I put my other hand in front of it was pushing A huge
amount of air (CFM). I said to my self there is some thing wrong here. Either most other fan manufactures use a different method of testing or these
fans are underrating how much air they actually push.

Another thing I was intrigued by the design. Instead of going with a aerodynamic approach like most other fan manufactures they went with a more
straight blade design witch makes more sense to me for increase air flow. The straight blades are more like scooping every last inch of air rather
than slicing through it. I have no super sophisticated equipment to prove this but I have good ears and a sense of touch and feel and I test all kinds
of computer fans almost every day in my business and it seems like these "Superb" silent computer fans are pushing a huge amount of air versus
noise level Db(a). I guess the secret may be in the blade design and the low noise in the SSO Bearing motor.

I now use the fans all the time and I highly suggest if your into quiet Performance give these fans a try, they will not disappoint. In my opinion they are
a quiet PC cooling enthusiast dream. And they will be the new standard in which all other fans should be judged by.

Also have a look at there other quiet computing products such a s chipset cooler, quiet CPU coolers and NEW! Xeon CPU Heat Pipe Heatsink.
