If the ducted fan of airplane model is used as the cooling fan of computer, is it effective?

That's a good idea. Do you want the computer to fly? But seriously, if we don't consider whether the computer power supply can adjust such a fan, the thrust generated by this fan alone may cause some damage to the internal accessories of the computer, and it will inevitably fail or even be completely damaged after a long time.

Generally, the motors of ducted fans are all 48V, 1 10A. Such a large voltage and current cannot be brought by ordinary computer power supply, even if the rated power is higher than1000 W.

The motor of this kind of fan generally adopts brushless motor with stator. This kind of motor has different stator diameters. The larger the diameter, the more turns of the winding coil and the greater the power. When it rotates, the noise of the motor itself is very loud, and with the sound of the fan blades, the noise will be even greater. For home users, this noise can be very annoying. Moreover, it may be because the fan generates thrust, which causes the whole chassis to vibrate or even shake, making the noise even louder.

In addition, the height of ducted fans is generally longer, which will make the internal space more crowded for smaller chassis.

Therefore, it is not a good practice to use the ducted fan of the model airplane to dissipate heat from the computer.

Hehe, what a coincidence. Unfortunately, I tried [covering my face]. Do you want to know the result? Let's just say that you can't stay for 1 minute without sound-proof earmuffs. The high-frequency sharp noise when the ducted fan runs at high speed is even more maddening than scraping the blackboard with nails. Tell me about my computer experience. In order to improve the rendering efficiency when I was doing special effects, I went to the computer city to install the dual Xeon x5670 machine and server motherboard. I feel that the original factory can't restrain the heat dissipation, and the Cpu temperature of the whole core and thread reaches 96 degrees. I changed the water-cooled one myself. In order to cool the water supply, I bought four Delta violent fans with independent switching power supply, each with an electric sound. I installed the rendering and turned on the fan at the maximum moment. I feel that the toss in front of me is nothing more than a waste of money. That noise, I feel my main engine has become a turbojet fighter. After all, the throttle has been turned on, and I just took off in the same place. Well, fortunately, I got off work, so I flew all night. The next day, I was flogged thousands of times by people who arrived early, and I quickly pulled it down after rendering. Then I went to Taobao and saw a ducted fan disassembled by the server. I bought it after I got it. After I turned it on ... no, no, no, I was saved. I want to take medicine. Who will help me [burst into tears]?

I am a model airplane athlete. Let's talk about it First of all, the chassis should use high-strength chassis, and iron can be used instead of aluminum and fixed on the table with screws. The minimum voltage required by the duct fan is 1 1. 1v, and the current is calculated according to the power of the duct. The air inlet and air outlet must be perforated horizontally, but it is not recommended to use a ducted fan, because this fan has a high speed and will produce a strong thrust. Screw.

Yes, there are essential differences between the cooling fans usually used on computers and the ducted fans on airplane models, except that the ducted fans have more power and air volume, and the blades and passages are changed, which increases the wind pressure. A similar fan is used on the server to dissipate heat, but the power is not as large as that used on the airplane model. On the one hand, the noise is too high (of course, the server is not afraid of noise), on the other hand, the server requires stable operation, so the requirements for cooling fans and the like are long life and durability, while the model airplane does not need it, and it runs at maximum load and has a short life.

If you want to hear the chassis take off, just buy a server fan. 10000 rpm.

It's all different sizes. What happened to them? Computer fans are large and thin, and ducted fans are small and thick. Not afraid of noise, just install a server-level active fan. Or do you need to specially modify a chassis?

Haha, the brain hole can be bigger. Wouldn't it be better to soak the motherboard in some special oil? There is a radiator outside, or a radiator as big as a wall, or a cooling tower as big as a building.

The noise is also great.

What matters is not the fan, but the size of the radiator! ! ! Unlike this radiator, it is noisy and not as effective as a tower, so it is better to cool it with water.

That's not noisy, it's too noisy.
