Do laptop fans work all the time?

The laptop will automatically detect the temperature, and only start the fan when the temperature is high, otherwise use the heatsink to passively dissipate the heat, and the fan will hear the sound of the fan turning when it starts;

The laptop will not turn on the fan when the laptop detects a low temperature, such as when the laptop is powered off, standby, running fewer programs, or when the external ambient temperature is low.

Theoretically, it's not

If the CPU temperature does not reach a certain temperature, the fan will not rotate, which plays an energy-saving role, after all, the battery life of the notebook is relatively weak.

But in fact the temperature of the CPU is always above a certain temperature (we become T), this.

t is the lowest temperature at which the fan works. So in life it feels as if the laptop fan has been working from the moment it is turned on.

Secondly, sometimes there are many programs running, and the load of the cup becomes larger, then the temperature is much higher than T, then the fan will speed up, and the sound of the fan will become louder when you hear it.

Automatically adjusted according to the temperature, this one has a slightly different design for each notebook, and most of them work all the time. It's just that the rotational speed changes according to the temperature.

Answer all kinds of notebook hardware questions, if you have a question, you don't have to be polite, please explain the fault phase of the model brand. Hi and user information ** and buckle consultation are available. Guidance to pay attention to problems, Beijing can also come to me directly.

Take the win10 system as an example, the specific reasons are as follows:

1. The laptop will emit a lot of heat when it is running, and if the heat cannot be dissipated quickly, it will cause the temperature of the laptop to be very high, so that the laptop fan will keep rotating.

2. The laptop fan keeps turning, it may be a problem with the settings, you can open the control panel of the computer and click "Hardware and Sound". Tap "Power Options" in the hardware and sound interface, click "Change Plan Settings", and click "Change Advanced Power Settings" in the pop-up window. Then click on "Processor Power Management", set the system cooling mode to "Passive", and then click OK to quit, so that the laptop fan will not keep turning.

3. If the air outlet of the laptop is blocked, resulting in a decrease in heat dissipation capacity, the temperature of the laptop will rise soon, which will cause the fan of the laptop to rotate all the time, and the blocked things at the air outlet can be removed to dissipate heat normally, so that the fan of the laptop will not rotate all the time.

4. If the switch chip of the notebook fan is broken, it will be turned on all the time, so that the notebook will keep turning as soon as it is turned on, and it can be sent to the computer repair department for repair.

Many times the fan of the laptop computer is slightly prone to some failures, either the fan does not rotate, or the fan does not stop, for this problem, how do we solve it? Let me tell you about it!

The solution to the laptop fan keeps turning

Analysis and its steps:

1 One of the motherboard BIOS settings in most people's laptops is that the CPU fan is always on, and there are generally two options, one is in battery mode and the other is in AC mode. The former is off by default and the latter is on by default). If this option is turned on, the fan will always be on, but only at low speed, regardless of whether the temperature exceeds the need to turn on the fan.

When the temperature exceeds the temperature required to turn on the fan, it will rotate at high speed. Turning this on will enhance heat dissipation and slow down the temperature rise, but it will produce noise (less noise), consume less power (very little), and shorten the life of the fan. It's recommended to open the book in summer or poor heat dissipation.,It's not necessary in winter.。

You pay attention to whether your computer keeps turning the fan as soon as it is turned on (if this is not enabled, it will stop after turning on for a while).

Solution: Press F10 to enter the BIOS settings when you see the HP icon when you turn on the computer (different models have different buttons, and there will be a small print prompt on the screen F*=Setup.) It's usually one of the keys F1 F2 F4 F10 F12 del, HP is generally F10), find the option with the word fan, and set the options behind it to disable.

This turns off the function of the fan always turning. The fan will only turn when the temperature of the computer rises to the point where it needs to be turned.

2.The temperature did exceed the temperature needed to turn on the fan. This means that the heat dissipation efficiency of your computer has decreased, usually because it has been used for a long time and there is more dust. It is recommended that you go to the after-sales service center to clean the dust.

In either case,Now the overall situation of your book is normal.,No serious problems.。 You can use it with confidence.

My laptop's fan keeps spinning, but it's because I want to run Blender and disable the discrete graphics card, and re-enable the graphics card, and the fan is normal.

The laptop's fan doesn't keep turning when it's on. This is true not only for Dell notebook computers, but also for all brands of laptops. The laptop's fan is intelligently speed regulated, sensing temperature changes according to the sensors inside the fuselage, running at high speed when the temperature is high, and running at low speed when the temperature is low, but it will not stop.

What to do if your laptop won't turn on:

1. If you encounter a situation where the laptop cannot be turned on, this problem may be caused by the static electricity on the motherboard chain hall.

2. Please plug and unplug the adapter and battery.

3. Please press and hold the power button for about 10 seconds, this will clear the static electricity on the motherboard.

4. Press and hold the power button for 30 seconds to do ECRESET (the charging light will go off first and then on).

5. After that, please insert the battery and adapter into the notebook and press the power button to turn it on.

6. The power indicator is on, which means that the motherboard is overpowered, but it may not be able to be turned on due to some devices.

7. Please remove the lithium battery and use the transformer for power supply directly. <>
