Noctua NF-A14 5V User manual

Dear customer,
Congratulations on choosing the Noctua NF-A14 5V PWM.
We from Noctua always strive to achieve superior quiet cooling performance
regardless of whether it’s a big 200mm fan or a small 40mm one.
That’s why the NF-A14 5V PWM sports many of the features and advanced
aerodynamic design measures of our award-winning larger models, making it
perhaps the most thoroughly optimised 140mm fan on the market.
Each Noctua fan is double checked for flawless operation by our quality control
team before it leaves the factory and I’m confident that you will be able to sense
some of the research, attention and care we’ve put into making this product.
Enjoy your NF-A14 5V PWM!
Yours sincerely,
Roland Mossig, Noctua CEO

In order to maintain maximum performance, please clean your fans regu-
larly using a duster, slightly moist tissue or canned air. Please be careful
not to use too much force in order to prevent any damage to the fan. Plea-
se don’t use a vacuum cleaner as this may apply excessive force to the
fan. In order to ensure flawless operation over many years of usage, the
NF-A14 5V PWM’s premium grade SSO2 bearing is fully sealed to pre-
vent the entering of fine dust particles. Please note that the fan is not
designed to be taken apart by the user. Removing the impeller from
the frame will break the sealing of the bearing and results in a loss
of warranty.
Cleaning and Maintenance
If you replace an existing fan, it is usually best to use the screws (or other mounting mechanisms) used for the original fan.
CAUTION: Being a 5V PWM fan, the NF-A14 5V PWM can not be run at 12V and will be damaged when used with typical 12V power sources such as PC
mainboard fan headers.
Depending on the application, it may also be possible to use the supplied mounting screws or silicone anti-vibration mounts.
For installing the fan using the NA-AV1 anti-vibration mounts, please first pull the mounts through the mounting holes of the case. Then put the fan onto the
mounts and pull them through the mounting holes of the fan:
Installation
2-3cm minimum!
After you’ve fixed the original fan’s cable to the OmniJoin adaptor using
the Skotchlok™ connectors, simply connect the NF-A14 5V PWM to the
adaptor in order to use it in your device.
Step 3
Then use flat nose pliers to push down the white button of the
Skotchlok™ connector. Make sure that the button is not jammed and
pushed all the way down. If the button is jammed, push it down from
both sides of the Skotchlok™ connector using the flat nose pliers.
Repeat Step 2 and 3 for the +5V lead.
Step 2
Then take one of the supplied 3M Skotchlok™ connectors and insert
the GND lead of the original cable and the black lead of the OminJoin
adaptor into the two holes of the Skotchlok™ connector. Make sure that
both leads are fully inserted and pushed all the way back.
Warranty and Support
Even with high-grade products and strict quality control, the possibility of
defects cannot be eliminated entirely. Therefore, we aim at providing the
highest possible level of reliability and convenience by offering a warranty
period of 6 years and direct, fast and straightforward RMA service.
Should you encounter any problems with your NF-A14 5V PWM, please

NF-A14 5V PWM | User Manual
Connection
The NF-A14 5V PWM comes with a 4-pin PWM fan connector for PWM
based speed control. Please note that the fan can also be connected
to standard 3-pin fan headers though. When connected to 3-pin fan
headers, the fan will run at full speed.
If you would like to run the fan on USB power sources such as devices
with USB host ports, power banks or USB power supplies, please use the
included NA-AC7 USB power adaptor cable.
Please note that the NA-AC7 must be used exclusively with the NF-A14
5V PWM fan because using it with other fans bears the risk of damaging
sensible USB host devices.
If you would like to connect the fan to other fan headers, please use the
supplied OmniJoin adaptor set as described below.
The fan features a short 20cm primary cable in order to help you minimi-
se cable clutter in typical applications. If you need a longer cable, please
add the supplied 30cm extension (NA-EC1).
Using the OmniJoin adaptor set
The supplied OmniJoin adaptor set allows you to easily connect the
NF-A14 5V PWM to proprietary fan headers.
After you’ve identified the individual leads, please proceed
with the following steps to install the OmniJoin adaptor:
Step 1
Cut off the connector of the fan that was originally used in the device.
Make sure not to cut the cable directly at the connector, there should be
least a 2-3 cm of cable left:
Please first identify the individual leads of the OmniJoin adaptor and
the original fan. The OmniJoin adaptor uses black for ground (GND) and
red for +5V. The black lead of the adaptor has to be matched with the
original GND lead and the red adaptor cable with the original +5V lead.
Many fan cables use the same colours as the OmniJoin adaptor, but
please note that there is no guarantee for this, so make sure to correctly
identify the GND and +5V leads of the original fan. Please refer to the
manual that came with the device or contact the device manufacturer
if in doubt.
