Installation
If you replace an existing 40mm fan with the NF-A4x10 5V in devices such as storage or network solutions, it is usually best to use the screws (or another mounting mechanism) used for the original fan.
CAUTION: Being a 5V fan, the NF-A4x10 5V 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 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
.
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
The NF-A4x10 5V features a standard 3-pin fan connector. If you would like to connect the fan to a 2-pin fan header, please use the supplied 3:2-pin adaptor (NA-AC2). Please note that there are different types of 2-pin connectors, so it is possible that the supplied adaptor doesn’t fit. In this case, please use the supplied OmniJoin adaptor set as described below. Note that the NF-A4x10 5V features an integrated polarity protection so there’s no risk of damaging the fan due to reversed polarity. However, the fan will not work when it is connected the wrong way around, so please make sure that it is connected correctly when using 2-pin connections. The NF-A4x10 5V 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-A4x10 5V to proprietary fan headers if you want to replace a 40mm fan in devices such as network or storage solutions. 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.
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:
- Step 2 Then take one of the supplied cable connectors and insert the GND lead of the original cable and the black lead of the OminJoin adaptor into the two holes of the cable connector. Make sure that both leads are fully inserted and pushed all the way back.
- Step 3 Then use flat nose pliers to push down the yellow button of the cable 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 cable connector using the flat nose pliers.
Repeat Step 2 and 3 for the +5V lead.
After you’ve fixed the original fan’s cable to the OmniJoin adaptor using the cable connectors, simply connect the NF-A4x10 5V to the adaptor in order to use it in your device.
Cleaning and Maintenance
In order to maintain maximum performance, please clean your fans regularly 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. Please 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’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, please don’t hesitate to contact our support team (support@noctua.at).
