NF-A20 PWM

User Manual

In order to ensure broad compatibility with today’s PC cases, the NF-A20 PWM features three

sets of mounting holes: While the 154x154mm and 110x180mm spacing allow it to replace

most 200mm fans, the 170x170mm spacing is used by many 230mm and 250mm fans,

which can thus also be replaced by the NF-A20 PWM.

As there is no fixed industry standard for the size or hole spacing of 200mm, 220mm,

230mm or 250mm fans, please carefully check both the hole setup of your chassis and

the available space (the NF-A20 PWM is 30mm thick whereas some other 200mm fans

are only 20mm or 25mm!) in order to verify that the NF-A20 PWM is compatible with

your chassis.

In case of doubt, please contact your chassis manufacturer.

Double-side design with long case-side endNA-AV3

Flat case-side endNA-AV4

For installing the fan using the NA-AV3 mounts:

Please first pull the F side through the fan’s mounting holes until pawl 1 is all

the way through the first hole.

The NF-A20 PWM comes with a 4-pin PWM fan connector for fully automatic speed

control via your motherboard’s 4-pin PWM fan headers. Please note that the fan can also

be connected to your motherboard’s 3-pin fan headers though. When connected to 3-pin

fan headers, the NF-A20 PWM will run at full speed (unless the motherboard supports

voltage based speed control).

If you’re using multiple NF-A20 PWM fans, you can use the supplied y-cable (NA-YC1)

to connect several fans to one PWM fan header. This way, your motherboard will set all

the connected fans to run at the same speed. The NF-A20 PWM 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-EC1).

The NF-A20 PWM comes with a Low-Noise Adaptor (NA-RC6) that allows you to reduce

the fan speed from 800 to 550rpm. You can either use the adaptor to set the fan to a

fixed speed of 550rpm (if speed control is deactivated) or to cap the maximum speed to

550rpm during PWM speed control.

The NF-A20 PWM includes both standard case fan screws and two types of silicone

anti-vibration mounts for installation.

While the double-sided NA-AV3 mounts are more convenient to install in space-re-

stricted environments, the NA-AV4 mounts with flat case-side end are flush with the

case panel and thus look tidier from the exterior.

If necessary, you can easily remove the NF-A20

PWM’s integrated anti-vibration pads:

Cleaning and Maintenance

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-A20 PWM, please don’t hesita-

Then pull the C side through the mounting holes of the case.

For installing the fan using the NA-AV4 mounts:

Please first pull the NA-AV4 through the mounting holes of the case.

Then pull the tip through the fan’s mounting holes until the pawl 1 is all the

way through the hole.

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-A20 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.

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.

Caution: Only pull pawl 1 through the first

hole. Don’t overstretch the mounts by pulling

pawl 5 through the opposite hole!
