Nanoxia FX EVO 120 PWM 1500
The Nanoxia FX EVO 120 PWM
1500 has a smaller box than the last model and it doesn’t come with a
speed controller.
The
packaging
The controller is not necessary since the
fan supports speed regulation based on PWN. The accessories are screws and
silicone pins.
The
accessories
The FX EVO 120 PWM 1500 looks similar to
the rest of the company’s fan models. We could only tell you that this model’s
speed ranges from 500 to 1,500RPM. The airflow varies from 24.2 to 58.5CFM, the
static pressure changes from 0.45 to 1.41mm of water, and the noise level is around
9.3 to 18dBA. Although there’s a small difference in top speed, from the FX EVO
120 IFC 1,600, this model can be considerably energy-saving: 0.96 instead of
1.56W. We’ll prove this right in practical tests below.
In our previous reviews for Nanoxia models,
we didn't tell you that their impellers are removable. Now, we are showing that:

Noctua NF-F12 PWM
We are sure that the Noctua NF-F12 PWM
is the fan having most technological advance in this review. Its detailed
description of technologies is too long for this review so we’re trying to give
you basic factors.

The
packaging
The attached paper is opened like a small
book, informing the customer of everything about the product.
The
product info printed on the box
Inside the cardboard box lies a plastic
packaging which contains spaces for the fan and accessories.
The
internal plastic packaging
The Noctua NF-F12 PWM is accompanied with
three cables: one Y-shaped splitter, four silicone pins and four screws.
The
accessories
This fan’s RRP is $19 plus a 6-year
warranty.
Noctua still keeps its design rules so this
new fan still complies with the same color mix as the company’s earlier
products. The beige-colored frame with brown corners and impeller is a doubtful
solution, in terms of beauty, but the fan cannot be mistaken among other models
of the manufacturers.
The NF-F12 PWM is obviously a new
product which is remarkably different from the previous NF-S12B and
NF-P12 products of Noctua. Its impeller has something between the impellers of
the fans mentioned above and features 7 wide blades having a sharp edges and a
thick ends.
The
product viewed from a tilt angle
It has a diameter of 113mm. The 41mm motor
is tightly glued to 11 broad spokes and has notches on the outside edge.
This solution means to help the airflow focus
onto one spot increase the fan’s static pressure.

Actually, the Noctua NF-F12 PWM has an
impressive static pressure: 2.61mm of water at a speed of 1,500RPM, which is much
higher than that of faster models in today’s review. The picture below indicates
the NF-F12 PWM’s advantages over the NH-U12P:

PWM vs. NH-U12P
The Noctua NF-F12 PWM’s blades are
installed to the motor to form an angle of 31 to 37 degrees to reduce noise.

arrangement
This makes the sound produced by the fan
more fluent and comfortable for user’s ears.

diagram of sound production
Another unique solution applied onto the
Noctua NF-F12 PWM is called Inner Surface Microstructures. It looks like
triangular cuts on the frame’s outer surface.
Inner
Surface Microstructure
It helps to reduce the turbulence between
the blades with the frame plus reduce noise and raise airflow.
In addition, the 4 silicone corners also help
to lower vibrations, the frame has 3 parts which are cut in inclined areas.
An
area that is cut out
This method is called Stepped Inlet Design,
increasing the airflow by increasing the incoming turbulence.

Inlet Design
The produced airflow is declared to be 55CFM
at 1,500RPM. If the fan is connected with the resistor and its speed is reduced
down to 1,200RPM, the air flow would be 43.7CFM. The Noctua NF-F12 PWM is expected
to produce a noise level of 9.3 to 18dBA.
Aside from the technologies mentioned above,
we should tell you that the fan uses Self-Stabilising Oil-pressure bearing
version 2.
Self-Stabilising
Oil
This optimization is to the narrow down the
distance between the fan’s axis and the magnet in order for a stronger magnetic.
The motor is still covered by a metallic layer rather than paper or sticker like
on other products.

This motor is expected have a longer
service life thanks to a metallic coat.

The Noctua NF-F12 PWM has a life time of
150,000h or over 17 years. Its motor is energy-saving thus it consumes below
0.6W at the peak speed. The cable’s length is around 0.5m.
