Is there a uniform factor that affects the speed of the fan?

The next CPU fan control software is on the line!

The fan speed is now generally controlled by the motherboard, and the control is based on the temperature, the speed is fast when the temperature is high, and the speed is slow when the temperature is low, which is to ensure that the temperature in your computer is not too high, so that the computer can run stably.

If you want to fix the fan at a speed, you can connect an external deceleration cable, so that the voltage is low, and the speed will be reduced, but the fan speed can no longer be controlled by the motherboard in the future.

Added: In addition to the speed of the fan can be automatically adjusted by the motherboard, its own indicators are also very important, and it is impossible for all fans to have the same speed. For example, your CPU fan may be 3000 rpm from the factory, while the case fan is 1500 rpm, and the graphics card fan is 4000 rpm.

There are three main indicators of the fan: speed, air volume, and diameter.

No matter how fast the speed is, how big the diameter, the air volume is the final effect, the air volume is not enough, the heat dissipation has no effect, no matter how high the speed is, it is useless, the air volume is enough, you can do 200 revolutions a minute. In other words, if you want to obtain the same large air volume, the fan with a large diameter can be adjusted to work at a very low speed, while the fan with a small diameter can only maintain a high number of revolutions, and forcibly reduce the number of revolutions, which will only lead to insufficient air volume and poor heat dissipation.

1. If the power supply fan does not rotate, it may be broken, or the line is unwelded and the sail is scattered.

2. If the power supply fan does not rotate, it will affect the speed of the computer's operation, the power supply element will be heated, the output power will decrease, and the power supply will gradually not move the computer, which will cause the computer to crash, restart, shut down, and in serious cases, it will burn the pants and destroy the power supply. It needs to be repaired quickly, and it should not be forcibly used.

3. If the fan is broken, the power supply fan is only 15 yuan, buy a fan back, and then remove the original one, cut the wire, connect the red line to the red line, and connect the black wire to the black wire. Try it to be a forward rotation and it can be used normally.

4. If the fan cord head falls off from the solder joint, take the power supply to any home appliance or mobile phone repair shop, and ask the master to weld it.

5. Since the power has been turned on for maintenance, you can clean the dust of the power supply by the way.

The CPU fan automatically adjusts the speed according to the CPU temperature, which is the most ideal situation, but there are also such situations, that is, no matter what you are doing, how high or how much the computer temperature is, the CPU fan speed remains the same, in fact, this is due to the problem caused by the computer's power management, as long as you set the CPU power management, you can adjust the CPU fan to automatically adjust the speed according to the temperature, let's understand the next steps:

1. Select System & Security in the Control Panel.

2. Select a power option.

3. Select High Performance Select Change plan settings.

4. Select Advanced Power Settings.

5. Select High Performance Select the sub-option to expand to make detailed settings.

6. The heat mode is divided into active and passive, the active mode means that the speed has been maintained at a relatively high speed, and the passive mode is to speed up only when the heat of the CPU is high.

7. CPU fan speed adjustment software.

First of all, determine whether the noise source is ufan, if it is, it depends on whether the fan is 4 pins, 3 pins can not adjust the speed, and then the software is useless, if it is 4 pins, any software can be adjusted, and it can be automatically adjusted according to the temperature without software. If you have 3 pins, you can consider buying a deceleration cord on **, about 2 yuan is actually a resistor in series to reduce the voltage of the UFAN, and the speed will be low! You can also consider buying a brand fan, the noise control is good, and the air volume is taken into account.

1. High and low power supply voltage: high speed of high power supply, slow speed of low voltage;

2. Capacitance capacity: the normal speed of the capacity is high, and the capacity decreases and becomes smaller, and the speed is slow;

3. Bearing lubrication, good lubrication, high speed, poor lubrication, bearing wear, slow speed.

The fan speed is directly related to the power supply voltage, followed by the local short circuit of capacitors, switches, motor windings, etc.

At present, the common use is related to the number of poles. Except for inverters.

Not necessarily. The power consumption of the electric fan is in two aspects, one is the wind energy generated by the rotation of the electric fan, and the other is the heat energy generated by the electric current in the circuit. The greater the proportion of wind energy generated in the power, the more efficient the fan will be.

If the inside of the fan is very hot, or if the fan blades are blocked, then the efficiency is very low. Depending on the wind power of the fan, the power must be multiplied by this efficiency.

For example, after some fans are aging, it may be difficult for the leaves to fan when the fan is turned on, and at this time, the power of the fan is manifested as circuit heating, and it seems that it doesn't matter if the size of the fan. So at this time, the motor of the fan is also easy to burn out.

That's why when turning on the fan, it is best to adjust it from high to low gear, that is, to make the fan turn up as soon as possible, so as not to consume all the power on the circuit and avoid the motor being burned. Hope to adopt.

Yes, the higher the speed of the fan, the greater the energy required to overcome the air resistance, and the greater the electrical power required.

If they fan blades at speed, wind pressure is generated.

and so on, the air pressure p of the rear end fan outlet will be increased. The air volume Q is no different from that of a single fan.

2.If the speed and wind force are different, the wind force in the front is strong and the wind force in the back is weak, the wind pressure generated in this air duct will still be larger than a fan, but the air volume is the same as that of a smaller fan.

3.The reverse of this, with answer 2The results are the same.

It's normal, the fan speed is automatically controlled, it is related to the temperature, and it looks good.

Your CPU fan speed is normal, generally above 2000 is normal, it is estimated that there will be the following reasons for the problem you said:

1. The machine has been used for too long, and the silicone is gone, so replace the silicone.

2. Medium viruses, some viruses will cause the CPU to overheat. Kill viruses or reinstall the system.

3. The machine is in a state of load for a long time, for example, the configuration of the machine is not high to run high-end games, resulting in excessive load on the processor.

Of course, it is recommended that you take apart the case and ship the machine to carefully observe whether the fan is running, as the test software can sometimes have errors.
