There is a temperature control chip in the laptop, which is usually a temperature control chip and a field tube to control the fan. When the temperature control chip detects that the CPU temperature is high, it controls the field tube to turn on and discharge, and the fan will rotate, and when the detection temperature is low, the field tube will not be conducted, and the fan will not rotate. It could be yours.

The laptop's temperature control chip is broken, or the fan hinge is entangled in a foreign object.

Hardware issue for sure! Hurry up and deal with it within the warranty period!

Hurry up and change the radiator, otherwise the high temperature will crash, I know it firsthand.

There are a few reasons why your laptop's fan won't turn:

1. The fan is broken.

2. The fan shaft is rusty.

3. Motherboard reasons.

4. Too much dust accumulates inside the fan.

The laptop's fan is a dual heatpipe system, with a keyboard convection cooling fan. The rotation of the laptop fan is related to the CPU temperature, and the fan will only rotate when the CPU reaches the warning temperature, which means that the fan will rotate during CPU use. If the laptop's fan doesn't rotate, it is likely to cause the computer to restart, crash, and in severe cases, burn the CPU and some components.

Most laptops have achieved BIOS-level hardware power management, taking the CPU cooling fan as an example, unlike the fan on the desktop computer that rotates as soon as it is turned on, the laptop fan is only installed in the CPU position, and the fan is only started when the BIOS detects that the CPU temperature exceeds the manufacturer's preset value, so there is often a phenomenon of rotation and stopping, which is very normal, and some manufacturers' fans can even adjust the speed according to different temperatures, so as to reduce power consumption to a minimum. So if you have friends who encounter this situation, don't worry, it's normal.

1. If the laptop does not turn, you should first consider whether the fan is broken, and if it is broken, you can only take it for repair or replace one.

2. If the fan is normal and does not rotate, there may be three situations:

a.There is too much dust accumulating inside the fan. When cleaning, remove the fan from the heat sink, open the bottom oil seal, wipe them off with a cotton swab or paper, or use a wooden toothpick to slowly wipe off the dust.

b.The fan shaft is rusty. Take the fan apart and apply some pomade to the top of the hinge. Generally, dip a straw or tweezer into the lubricating oil, and drop a drop of lubricating oil in the shaft, not too much, and be sure not to use edible oil.

c.Motherboard reason. The less minor is only the damage to the power supply transistor, and the complex involves many components, such as the temperature control circuit.

If there is a fault in the relevant circuit during IBM notebook repair, for example, there is a problem with the temperature monitoring circuit of H8, a fan error error will be reported. At this time, it can only be sent to a professional repair shop.

Reason 1: When our computer is very hot, the fan still doesn't start to dissipate heat to cool down, and it only turns when we turn it on. The reason is that the cooling fan of the computer is mainly used to cool the CPU of the computer, and the back panel of the computer is not only the CPU will heat up, it may be that the temperature of other accessories is too high, such as computer hard disk, graphics card, motherboard, etc.

Here's a way to test if there's a problem with the cooling fan, that is, if we open a large game with high CPU requirements, if the cooling fan still doesn't work, it's the failure of the fan itself. Reason 2: The laptop becomes slower and slower the more you use it, and there are problems such as crashing and restarting for no reason, the body temperature is too high, and you can't hear the sound of the cooling fan working.

The reason may be that the cooling fan of the laptop did not meet the standard when it was installed, and the installation was unqualified, so the cooling fan could not operate normally. We can remove the cooling fan of the laptop and reinstall it. Reason 3:

The computer will turn on normally, but it will shut down after running for a while, and you will need to wait a while before it can continue to turn on. This may be due to a foreign object that is obstructing the permeability of the cooling fan or fan duct. Therefore, the CPU temperature of the computer is too high, and self-protection is turned on, causing the computer to shut down automatically.

At this time, we can take the notebook apart and remove the foreign matter. Reason 4: The CPU cooling fan does not rotate when it is running.

However, the temperature of the computer itself is relatively high. The reason is that the CPU temperature of the laptop has not yet reached the temperature at which the cooling fan works. Generally, laptops need to be above 70 degrees Celsius for the cooling fan to work.

This answer applies to most computer models such as the Dell G15.

If the temperature of the laptop is too high during use, and the fan does not rotate, it means that its internal parts have a certain fault, and it is necessary to shut down the computer in time and find a technician for inspection and maintenance, so as to achieve a better degree of safety.

This could be a problem with the fan's power cord, causing the fan to not work properly.

The cooling fan needs to be cleaned and replaced, and it is recommended to install a Master Lu to monitor and protect it.

You can contact the after-sales service to ask.

Summary. Dear, hello, I'm glad to answer for you, laptop CPU temperature low fan does not turn solution CPU fan power failure. Under normal circumstances, the CPU fan is powered by the motherboard, and the power supply interface can be found by following the fan's cable.

If you find that the cable is loose, you can try to reconnect it and plug it firmly at the interface...CPU fan dust block. If the desktop is used for a long time and is not cleaned, it will cause dust deposits on the CPU fan and block the fan blades.

Remove the CPU fan under and use a brush to clean it、On the fan hinge。 The CPU fan itself is faulty. If the above reasons are ruled out, then it is most likely that the CPU fan has burned out and cannot work.

CPU fan dust block. If the desktop is used for a long time and is not cleaned, it will cause dust deposits on the CPU fan and block the fan blades. Remove the CPU fan under and use a brush to clean it、On the fan hinge。

The CPU fan itself is faulty. If the above reasons are ruled out, then it is most likely that the CPU fan has burned out and cannot work. In this case, you need to purchase a matching CPU fan and reinstall it.

The fan rotates, but when you open the game, the fan rotates slowly, and the frame rate of the game is very low, so the fan rotates very slowly.

No, I have more than a thousand gigabytes of memory, and I won't run out of memory because the game is big.

If the accumulated dust is too large, remove the CPU fan and use a brush to clean it.

60 degrees is not too high, but if the 80 degrees fan doesn't turn, I think it's a problem.

The new original ASUS laptop fan has a built-in CPU fan AMD

It's normal that the laptop's fan doesn't turn on and can't turn on.,It seems that there is a fan in the CPU.。 That's going to be.

It's not going to turn around, go fix it.
