Why is the laptop fan running so slowly

I analyze the reasons for this:

1. If the temperature value set by the computer to make the fan speed rise is not reached, the use of the fan is determined according to the temperature of the computer, as long as the temperature is not high, the fan sometimes does not rotate, this is also normal.

2. When the temperature is abnormal, the fan will speed up, if your temperature is abnormal and the fan speed is still very slow, it is likely that the fan has accumulated too much dust.

3. It may be a computer software limit, such as Samsung BatteryManager and SpeedUp

The manager can limit the fan speed by driving.

The fan is slow, because the temperature of the CPU and the computer is not high enough. The fan has an intelligent adjustment function, which will rotate faster when the temperature is high.

The laptop's fan is automatic, not running at full speed all the time!

It is automatically adjusted, but can be changed to a constant rotation.

This allows for better heat dissipation.

I can change it.

Let's sum it up:

The temperature of the CPU you said is very normal, it means that your computer is not heating much now, not enough or not reaching the temperature value set by the computer to make the fan speed rise, the use of the fan is determined according to the temperature of the computer, as long as the temperature is not high, the fan sometimes does not rotate, this is also normal.

If you don't worry, you can monitor the temperature of your computer's CPU, etc., and there is a small software that can display it!

The speed of the fan rotation is based on whether you use the computer to watch ** or play games, and playing games generally rotates faster, because the CPU and motherboard have high temperatures and need to be cooled down. And you generally surf the Internet and browse the web, the CPU temperature is average, which is that the fan sometimes does not turn or turns very slowly.

1. This is a temperature control circuit on the motherboard, and the CPU temperature is set within a certain range, which will run silently and at low speed, which is a normal phenomenon;

2. The fan has accumulated dust or the internal lubricating oil is dry, resulting in a slow speed, and it is necessary to clean up the dust or replace the fan. This phenomenon often appears on cheap tubular axle fans, although it can be repaired with lubricating oil, but it will be repeated soon after, it is recommended to replace the roller (ball) fan;

3. The high-end fan comes with temperature control adjustment, and when the radiator temperature is low, it runs at low speed, which is also normal;

4. There is a problem with the motherboard circuit or fan circuit, resulting in a low fan speed, which needs to be repaired and replaced.

5. Some low-speed fans with large air volume have a lower operating speed, but it can provide a larger air volume, and such fans are generally large in size.

6. If there is too much dust at the air outlet of the notebook, then the heat will be reflowed, and the heat dissipation capacity of the notebook will definitely be greatly reduced. After cleaning the air outlet, you can take off the fan and clean it directly with a cotton ball, and it is best to remove the heat dissipation module of the air outlet directly for cleaning.

7. The silica gel between the CPU and the heat dissipation module needs to be replaced, this layer of silicone is used to guide the temperature of the CPU to the heat dissipation module, if the silicone is dry, the heat dissipation capacity decreases, the CPU heat cannot be dissipated, and the speed of the notebook will slow down.

3.The speed of the electric fan slows down, it's a pity to throw it away, teach you 2 tricks, easy to repair, as fast as new 2

Maybe it's because the coil is aging, or maybe it's dirty on the blades, so if you don't bother, remove it and clean it. After all, it's been used for a few years, otherwise it will be replaced with a new one.

If the fan speed is too slow, you can add some lubricating oil to the shaft rod.

The fan is removed to clean the ash, and the motor is added with some oil.

If the desktop computer fan speed is too fast, if it is a temperature-controlled fan, it can be adjusted, but if it is not temperature controlled, there is no way to adjust it, and the fast fan speed means that he is in the extreme heat dissipation is also good for the CPU.

The original fan of the desktop computer or the first-class auxiliary fan can be perfectly matched with the motherboard, and the fan speed can be intelligently adjusted by detecting the temperature. If the temperature is high, the fan speeds up to facilitate heat dissipation. If the temperature is not high, the speed will be kept low.

However, some poor quality radiator fan interface does not have enough pins to cooperate with the temperature control speed detected by the motherboard, and it always runs at high speed. It is not possible to manually adjust the rotational speed.

You can adjust it in the BIOS, but it is not recommended, the computer is mainly cooled by the CPU fan, if you turn it down, it can make the computer temperature too high, if you lower it a little bit, it will have no effect, simply change to a silent fan.

If the fan speed of the desktop computer is too fast, it can be adjusted and entered into the BIOS. Place the computer on the fan. Set it to smart mode or silent mode, and it will be based on this time.

The temperature of the CPU. Change the speed of the fan. Don't choose the maximum mode.

Generally, today's computer motherboards support CPU fan temperature control, that is, when the CPU temperature is high, the fan speed will rise, and the temperature will decrease when the temperature is low, so it is best not to change the fan speed privately.

Most motherboards are designed for four-wire fans, and the speed of the fan can be adjusted through the motherboard BIOS settings, including intelligent speed regulation. If the fan is three-wire, most motherboards can't adjust the speed, and only a few motherboards can adjust the speed of the three-wire fan (some motherboards can).

For fans that cannot be adjusted by the motherboard, you can purchase a speed control cable, or change to a high-volume, low-speed fan.

Some motherboards can be set, but it is not recommended to set it, it is all automatic, if it is set, it will cause poor heat dissipation, and the processor performance will be reduced.

Can you slow down the speed of the desktop computer fan if it is too fast, the fan of the computer radiator can generally be set if it is a four-wire cable. However, the three-wire radiator basically cannot be adjusted.

If it can be adjusted, go to the motherboard BIOS to adjust it.

The fan speed can be adjusted in the BIOS settings. You can also set the system cooling mode in the processor power management in the system, and adjust the CPU fan speed in the processor state.

The rotation beam of this fan cannot be adjusted, and you can buy fans with different speeds.

First, your motherboard and fans can be adjusted, and second, if you adjust them, the case may overheat and cause performance to deteriorate.

If it is a smart fan, it means that the CPU temperature is high, clean the fan to dissipate the CPU and add heat dissipation grease, the temperature will be lowered, and the speed will be slow.

What model of your machine specifically? Generally, the computer fan is an intelligent speed, and the speed is fast when it is hot, and the speed is slower if it is not hot, which is relative.

It is possible that the shaft lubricating oil of the fan is gone, and the fan blades are dusty. Dismantled the notebook, dusted the fan, and lubed it with some lubrication. Generally, it can be improved.

The fan is slow, because the temperature of the CPU and the computer is not high enough. The fan has an intelligent adjustment function, which will rotate faster when the temperature is high.

It's normal that in order to save power, the fan speed of the laptop is automatically adjusted.

It is automatically adjusted, but can be changed to a constant rotation.

This allows for better heat dissipation.

I can change it.
