This fan is really brutal! ! ! ! ! !

Brand new original Japanese Nidec supercharged cooling fan,

Specification 80*80*56 MM,

It is composed of two 8028 violent fans, DC12V 6.65A,

The power is very powerful, and the air is supplied by the front fan,

The fan at the back is pressurized again, with super large air volume, and the front fan reaches 15,900 rpm.

The speed of the supercharged fan behind has reached 13,800 rpm, which is a super high speed.

When the whole fan works at full speed, the sound is almost comparable to that of an airplane engine.

Just listen to this sound to know the huge amount of wind.

(Friends who need a quiet sound, please stay away from this fan) And the two fans are all high-speed imported bearings, brushless motors, which are themselves super long life.

These babies are very rare and good babies,

It is generally used as a cooling fan on high-end servers.

Cooling fans are generally light in weight,

But the weight of this fan reached 376 grams,

It's heavy in your hand, exquisitely crafted and high-end!

This batch of fans is a relatively recent product, it has reverse connection protection,

If the positive and negative poles of the fan are connected incorrectly,

The fan just doesn’t work and it won’t burn out the drive board.

And its driver board still starts slowly,

That is, it takes about 1 second to start working after turning on the power.

It can only connect the positive and negative poles of the fan,

The fan will run at the highest speed,

You can also input PWM,

The duty cycle is used to control the speed.

When we actually measure DC12V, the current is 5.75A,

The maximum speed of the air inlet fan is 15900 rpm,

The maximum speed of the air outlet fan is 13,800 rpm.

At such a high speed, its blades are almost as dangerous as a flying knife.

Please pay attention to safety when using,

It’s best to install the protective cover before using it.

Take care of your precious personal safety,

It should always come first.

The front fan and the rear fan are two sets of independent terminals, both of which are four wires.

The red wire of the front fan is the positive pole, the black wire is the negative pole, and the blue wire is the PWM.

The orange-red wire of the rear fan is the positive pole, the brown wire is the negative pole, and the blue wire is the PWM.

The white wire and the yellow wire should be feedback signals, and no wiring is required.

This fan can only be connected to the positive and negative poles, and the fan will run at the highest speed.

For example, the front fan, if the red wire is connected to the positive pole and the black wire is connected to the negative pole,

The front fan can run at the highest speed.

You can also connect the PWM signal to the blue wire,

The negative pole of the PWM can also be connected to the black wire,

Then you can use the duty cycle to adjust the speed,

But its adjustable range is mainly concentrated in the latter half of 50%-99%,

The effect of 20%-50% is not obvious.

Ordinary buyers and friends usually only have one set of power supplies.

So you can also connect the red wire and orange wire in parallel to the positive pole,

The black wire and the brown wire are connected in parallel to the negative pole,

The blue wire and the blue wire are connected in parallel to the PWM,

So the method of use is the same,

But please note that if you only want to run the front wind pole or the rear fan (only one fan is running),

You can’t connect the blue wire and the blue wire in parallel,

Otherwise it cannot be started,

For example, these two lines are connected together,

Then connect the red wire to the positive pole and the black wire to the negative pole,

The fan could not be started then.

Fan specifications: 80*80 MM

Fan thickness: 55.8 MM

Cable length: about 140 MM

Weight: 376 grams

Voltage: DC12V

Current: 6.65 A (measured 5.75 A)

Power: Approximately 80 W

Maximum speed of front fan: 15900 RPM

Maximum speed of rear fan: 13800 RPM

Power on the test machine, this is really very violent, please note that the power supply current must be at least 8A, if it is too small, it will not even start.

And friends who need a quiet voice, please don’t shoot this fan.

The sound at its highest speed can be said to be very loud,

It is a fan with high power density,

Its air volume is huge, but it is not concentrated, it is scattered,

So the closer you get, the stronger the wind will be.

Japanese (Nidec) fans, quality has created the brand, quality is of course leveraging,

Especially this kind of high power density fan,

More demanding high-quality requirements,

Generally only high-end uses such as servers,

I can afford such an expensive fan.

Nidec's high-power density 8056 fan,

The ex-factory price is definitely high,

Ordinary products don't dare to pay such a heavy cost.

In fact, this fan can be broken down into two independent 8028 fans,

Pry the two buckles apart and rotate it,

Can be separated into two fans,

And the two fans are independent terminals,

It’s still very violent to split into two fans.

The front fan is 3.65A when DC12V,

The rear fan is DC12V2.15A,

It's already very violent to use,

And the current of the power supply doesn’t need to be that big,

It is more suitable for DIY enthusiasts to use.
