NF-A4x10 5V PWM | User Manual
Installation
If you replace an existing 40mm fan with the NF-A4x10 5V PWM in devices such as storage or network solutions, it is usually best to use the screws (or other
mounting mechanism) used for the original fan.
CAUTION: Being a 5V fan, the NF-A4x10 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.
When installing the NF-A4x10 5V PWM as a case fan, you can either use the supplied mounting screws or NA-AV3 silicone anti-vibration mounts. For installing
the fan using the NA-AV3 mounts, please first pull the F side through the fan's mounting holes until pawl 2 is all the way through the hole.
Caution: Only pull pawl 2 through the first hole.
10mm
Don't overstretch the mounts by pulling further pawls through!
Then pull the C side through the mounting holes of the case. 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.
Connection
Please first identify the individual leads of the OmniJoin adaptor and
the original fan. The OmniJoin adaptor uses black for ground (GND) and

to standard 3-pin fan headers though. When connected to 3-pin fan
headers, the fan will run at full speed.
Many fan cables use the same colours as the OmniJoin adaptor, but

must be used exclusively with the NF-A4x10 5V PWM fan because using
it with other fans bears the risk of damaging sensitive USB host devices.
If you would like to connect the fan to other fan headers, please use the

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.

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 fixed the original fan's cable to the OmniJoin adaptor using
the Skotchlok™ connectors, simply connect the NF-A4x10 5V PWM to
the adaptor in order to use it in your device.
Cleaning and Maintenance
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-A4x10 5V PWM'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.
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-A4x10 5V PWM, please don't
hesitate to contact our support team (support@noctua.at).
