That’s why the NF-A12x25 5V sports many of the features and advanced
aerodynamic design measures of our award-winning larger models, making it
perhaps the most thoroughly optimised 120mm fan on the market.

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.

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-A12x25 5V’s premium grade SSO2 bearing is fully sealed to prevent
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 fan, the NF-A12x25 5V 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-AV2 anti-vibration mounts, please first pull the F side through the fan’s mounting holes and then pull the C side through
the mounting holes of the case:
Installation Connection After you’ve fixed the original fan’s cable to the OmniJoin adaptor using
the Skotchlok™ connectors, simply connect the NF-A12x25 5V to the
adaptor in order to use it in your device.The NF-A12x25 5V features a standard 3-pin fan connector. However,
please note that the fan can also be connected to standard 4-pin fan
headers.
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-
A12x25 5V fan because using it with other fans bears the risk of dama-
ging 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 minimise
cable clutter in typical applications. If you need a longer cable, please
add the supplied 30cm extension (NA-EC2).
Using the OmniJoin adaptor set
The supplied OmniJoin adaptor set allows you to easily connect the
NF-A12x25 5V to proprietary fan headers.

2-3cm minimum!
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.
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.
If the long ends of the mounts are in the way, you can use scissors to cut them after installation.
Note that this will then make them difficult to reinstall in the future.
If you prefer anti-vibration mounts with flat case-side ends, please purchase the optional NA-AV4 mounts.
