Noctua NF-A12x25 ULN - Cooler Manual

Introduction

Dear customer,

Congratulations on choosing the Noctua NF-A12x25 ULN.
Our fans are renowned for their impeccable quality and outstanding longevity and like all Noctua fans, the NF-A12x25 ULN features an MTTF rating of more than 150.000 hours that's backed up with our 6 years manufacturer's warranty.
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-A12x25 ULN!

Yours sincerely,

Roland Mossig, Noctua CEO

Installation

For installing the NF-A12x25 ULN on a CPU heatsink or watercooling radiator, please use the fan mounting mechanism supplied with said product (fan clips, screws, etc.).

For optimal cooling performance on watercooling radiators, it is recommended to change the stock NA-AVP1 anti-vibration pads for the included NA-AVG1 anti-vibration gasket in order to reduce 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 replace an existing 120mm fan with the NF-A12x25 ULN in other devices, it is generally recommended to fix it with the screws (or other mounting mechanism) used for the original fan.

When installing the NF-A12x25 ULN as a case fan, you can either use the supplied mounting screws or NA-AV2 silicone anti-vibration mounts.

For installing the fan using the NA-AV2 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:

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.

Connection

The NF-A12x25 ULN features a standard 3-pin fan connector. Please note that the fan can also be connected to 4-pin motherboard fan headers though. If you would like to connect the fan directly to your power supply, please use the supplied 3:4-pin adaptor (NA-AC1).

The NF-A12x25 ULN 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).

The NF-A12x25 ULN comes with an Ultra-Noise Adaptor (NA-RC12) that allow you reduce the fan speed from 1200 to 900rpm in order to achieve even quieter operation.

Cleaning and Maintenance

Fans inside computer cases tend to accumulate dust over longer periods of usage. 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-A12x25 ULN'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.
