Installation
For installing the NF-A12x25 FLX on a CPU heatsink or watercooling radiator, please use the fan mounting mechanism supplied with said product (e.g., fan clips, screws).
For optimal cooling performance on watercooling radiators, it is recommended to replace the stock NA-AVP1 anti-vibration pads with the included NA-AVG1 anti-vibration gasket. This reduces air loss between the fan and the radiator.
The NA-AVG1 gasket can also be used for other applications that benefit from a tighter seal with the fan.
If you are replacing an existing 120mm fan in other devices with the NF-A12x25 FLX, it is generally recommended to fix it using the screws or mounting mechanism used for the original fan.
When installing the NF-A12x25 FLX as a case fan, you can use either the supplied mounting screws or the NA-AV2 silicone anti-vibration mounts.
Installing with NA-AV2 mounts
To install the fan using the NA-AV2 mounts, first pull the 'F' side through the fan's mounting holes, and then pull the 'C' side through the mounting holes of the case.
F = fan side
C = case side
If the long ends of the mounts obstruct, they can be trimmed with scissors after installation. Note that this will make future reinstallation difficult.
For anti-vibration mounts with flat case-side ends, please consider purchasing the optional NA-AV4 mounts.
Connection
The NF-A12x25 FLX features a standard 3-pin fan connector. The fan is also compatible with 4-pin motherboard fan headers.
To connect the fan directly to your power supply, use the supplied 3:4-pin adaptor (NA-AC1).
The NF-A12x25 FLX includes a short 20cm primary cable to minimize cable clutter in typical applications. If a longer cable is needed, use the supplied 30cm extension cable (NA-EC2).
The NF-A12x25 FLX comes with Low-Noise Adaptors (NA-RC15) and Ultra-Noise Adaptors (NA-RC13). These allow you to reduce the fan speed from 2000rpm to 1700rpm (NA-RC15) and 1350rpm (NA-RC13) respectively, for even quieter operation.
Cleaning and Maintenance
Fans inside computer cases tend to accumulate dust over time. To maintain maximum performance, clean your fans regularly using a duster, a slightly moist tissue, or canned air. Exercise caution not to use excessive force to prevent damage to the fan. Avoid using a vacuum cleaner, as this may apply too much force.
To ensure flawless operation over many years, the NF-A12x25 FLX's premium grade SSO2 bearing is fully sealed to prevent the ingress of fine dust particles. Please note that the fan is not designed for user disassembly. Removing the impeller from the frame will break the bearing's seal and void the warranty.
Warranty and Support
Despite high-grade products and strict quality control, the possibility of defects cannot be entirely eliminated. Noctua aims to provide the highest level of reliability and convenience through a 6-year warranty period and direct, fast, and straightforward RMA service.
