NOCTUA NF-A14x25 G2 PWM Sx2-PP
INSTALLATION MANUAL
Caution: Do not overtighten radiator screws! The total
compressive load on all 4 screws must not exceed 30kg
(equivalent to ~0.15 − 0.25Nm torque with typical M3 or
UNC 6-32 screws). Be extra careful with M4 or fine threads as
they can produce higher compressive load with lower torque.
Caution: Please remove the protective paper from the inside
of the fan frames before use.
For installing your NF-A14x25 G2 PWM fans on a CPU
heatsink or watercooling radiator, please use the fan
mounting mechanism supplied with said product (fan clips,
screws, etc.).
Caution: The NF-A14x25 G2 is a high-precision device with
extremely strict tolerances. Therefore, it is critical to avoid
excessive forces acting onto the frame when installing the
fan on water cooling radiators:
On the outlet side of the fan, only use anti-vibration pads
and gaskets with rings around the mounting hole when
installing the fan with the outlet side facing the radiator
(“push” orientation). These rings reduce the load onto the
frame significantly.
Do not use pads or gaskets without load-relief rings on the
outlet side of the fan in “push” configurations! On the inlet
side, both types can be used.
When installing the NF-A14x25 G2 PWM 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:
F = fan side C = case side
NO

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.

Dear customer,
Thank you very much for choosing the Noctua NF-A14x25
G2 PWM Sx2-PP.
The NF-A14x25 G2 PWM Sx2-PP is a set of two
NF-A14x25 G2 PWM square-frame 140mm fans for
push-pull operation such as on water cooling radiators.
When two fans operate in a push-pull configuration
running at the exact same speed, their acoustic interaction
can lead to undesirable harmonics phenomena such as
intermittent vibrations or periodic humming. Therefore,
the two NF-A14x25 G2 PWM fans contained in the Sx2-PP
set are slightly offset in speed (+/- ~25rpm) in order to
ensure optimal acoustics in push-pull configurations.
Enjoy your NF-A14x25 G2 PWM Sx2-PP fans!
Yours sincerely,
Roland Mossig, Noctua CEO
