Noctua NF-A4x10 24V PWM Installation Manual

Dear customer,
Congratulations on choosing the Noctua NF-A4x10
24V PWM.
We at Noctua always strive to achieve superior quiet
cooling performance regardless of whether it's a big
200mm fan or a small 40mm one. That's why the
NF-A4x10 24V PWM sports many of the features
and advanced aerodynamic design measures of our
award-winning larger models, making it perhaps the
most thoroughly optimised 40mm fan on the market.
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-A4x10 24V PWM!
Yours sincerely,
Roland Mossig, Noctua CEO

Installation
1
If you replace an existing 40mm fan with the
NF-A4x10 24V PWM in devices such as 3D printers,
it is usually best to use the screws (or other mounting
mechanism) used for the original fan.
Caution: Being a 24V fan, the NF-A4x10 24V cannot
be run at 12V and requires a starting voltage of at
least 17V. It is therefore not suitable for standard PC
applications.
For installing the fan using the NA-AV3 anti-vibration
mounts, please first pull the F side through the fan's
mounting holes until pawl 2 is all the way through the
first 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.
2 Connection
The NF-A4x10 24V PWM comes with a 4-pin PWM
fan connector for PWM based speed control. Please
note that the fan can also be connected to standard
3-pin fan headers, though. When connected to 3-pin
fan headers, the fan will run at full speed.
The included NA-AC9 adaptor cable allows the fan to
be connected to the 2-pin JST XHP-2 2.5mm sockets
used on many popular 3D printer models (e.g. Creality
Ender 3 and CR-10, Anycubic Mega).
If you would like to connect the fan to other fan
C = case side
headers, please use the supplied OmniJoin
set as described below.
The fan 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-A4x10 24V PWM comes with a Low-Noise
Adaptor (NA-RC8) that allows you to reduce the fan
speed from 5000 to 4100rpm. You can either use the
adaptor to set the fan to a fixed speed of 4100rpm (if
speed control is deactivated) or to cap the maximum
speed to 4100rpm during PWM speed control.
Using the OmniJoin
3
The supplied OmniJoin
easily connect the NF-A4x10 24V PWM to proprietary
fan headers.
Please first identify the individual leads of the OmniJoin
adaptor and the original fan. The OmniJoin
uses black for ground (GND) and red for +24V.
The black lead of the adaptor has to be matched with
the original GND lead and the red adaptor cable with
the original +24V lead. Many fan cables use the same
colours as the OmniJoin
there is no guarantee for this, so make sure to correctly
identify the GND and +24V leads of the original fan.
Please refer to the manual that came with the device or
contact the device manufacturer if in doubt.
Caution: Only pull pawl 2
through the first hole. Don't
overstretch the mounts
by pulling further pawls
through!
