How can I see if the fan in the host unit is spinning?

That is, when you disassemble the side panel of the case, you can see that the fan inside is not turning.

One is listening. The second is to open it, and the third is to ask the master.

When you put your hand on the case, you can feel it at the power supply.

Some motherboards come with small software that allows you to check the number of CPU fan revolutions.

Whether the graphics card fan is turning or not, it's time to open the case.

One is [open the case], and the other is that the software can view the speed if you want to view the optimization master

There is no need to look at it, if the fan does not rotate, it will crash inexplicably, and you can disassemble the chassis to see if you find that it often crashes inexplicably.

Just take apart the back cover and take a look, or turn off the stereo and listen carefully on the case.

Step 1: The computer has been used for a long time, the water molecules in the space will cause the oxidation of the memory surface and produce oxides, which will cause the contact surface of the memory and the motherboard to easily cause poor contact, the solution is relatively simple, after the power is off, dial the memory down, use the eraser to remove the oxide on the memory surface, and insert it back. Step 2:

Motherboard BIOS error failure can also cause this problem, try to restore the BIOS settings to factory settings, we remove the coin cell battery from the motherboard, leave it for a few minutes, and then install the coin cell battery in its place to restore the initial BIOS value. It is also very simple to remove the button battery, pull the buckle outward, and the button battery can be automatically ejected, and you can remove it directly.

Step 3: The electronics themselves have adsorption. Coupled with the use of the environment, for a long time, it may cause dust to accumulate on the surface and interface of each accessory, we can use a brush, high-power hair dryer to clean up the dust.

Step 4: If the above methods are tested or still do not work, then it may be caused by the failure of the power supply or motherboard, only take the computer host to the computer store for testing, rule out whether it is a problem with the power supply, if the power supply is still the problem, and finally replace the motherboard to try. If the hardware is covered by the warranty, you can contact the after-sales service.

The fan keeps turning after the computer is turned on, which proves that the computer's power supply is fine. It can be powered normally. But it can't be turned on, it may be that there is a problem with the CPU or memory.

You can check it by opening the case, see if the fan above the CPU is rotating normally, plug and unplug the memory module again, and then try to see if it can be turned on.

There are switching power supply fans and case cooling fans behind the main computer unit, which will run for heat dissipation after the main unit is turned on.

If the fan does not turn after the computer is turned on, it is easy to automatically protect the motherboard due to the high temperature in the case, resulting in system crash, black screen and other phenomena.

Generally, the air duct of the chassis using a side-blowing fan is like this:

Generally, it rotates, no matter how cold the weather is, it's just that the speed will be fast or slow, but it is not excluded that intelligent temperature control is not excluded, but I have not seen such a power supply. And intelligent temperature control is more common in audio equipment,For example, the Philips speaker I use now,If you don't play a song or too loud,It doesn't turn,The temperature will turn when it's high to a certain extent,This is because of the temperature control chip,I hope it can help you!!

Well, almost, because the computer hardware is running at full speed to start when the computer is turned on, the fan has to turn.

That's the power fan, which will turn when it is turned on, and the case fan generally does not have thermal induction, as long as it is assembled, it will also turn when it is turned on, so don't worry.

Normally, there will be two or three fans inside the computer that will start running when you turn it on.

As long as your computers are powered on, they won't stop running to keep cooling.

When your host fan doesn't rotate or the speed is low, then you have to pay attention, there may be a problem with the fan.

Yes, as soon as you press the power button, it will turn normally, and that is for power supply heat dissipation.

If the fan doesn't turn, it's faulty. At present, the intelligence of the host power supply fan does not seem to be so high, no matter if you are in winter or summer, it will turn when the power is on, otherwise it will be broken.

You're talking about the fan of the power supply, which does turn on as soon as it is turned on.

The cooling fan starts working as soon as it is turned on.

Of course, when you plug it in, it will definitely turn.

Maybe you guys called, so it was transferred!

Take the state of tung jujube to the after-sales maintenance point in the maintenance of the maintenance, and they will test it.

If it is out of warranty, the wheel will be disassembled, and the 3-5V battery will be disassembled to test whether the fan will rotate, and it will turn is the sail of the temperature control chip.

Hello, you remove the fan and load the 5v (usually 5v) voltage. Discretion. If the fan is rotating, just say and accompany it to be a temperature control chip problem... Of course, you also have to look at the speed of the stove base. . .

This one. It should be your monitor problem, right? Try a different monitor and graphics card.

No need to buy. Try a different set first and see if it's the reason for this. If the CPU and power supply fan are turned on the computer.

It should have been turned on, and what you said should just be that the monitor doesn't show the disadvantages, right? Chong clan.

The simple way is to find a good fan to replace it and see if it can work properly, if it doesn't work, it is a chip reed limb problem. This method of dressing up in the world is low in imitation, so it is recommended to try it.

On the first hand, the fan is only broken because there is too much wear and tear, and the noise becomes louder, and it is less likely that the fan does not rotate. The computer was powered off due to high temperature, and the fan still didn't rotate, and I also thought it was a chip problem.

1. If the fan does not rotate when you press the power button to turn on, it is recommended to enter the "Lenovo Commercial Key Customer **Xiangzhi Eggplant", click "Expert **Service" to consult the engineer for repair, or click "Appointment Maintenance" for self-service repair equipment.

2. If the fan is rotating when the machine is turned on, and the fan does not rotate during use, please confirm whether the computer will crash or automatically power off during use. Because the current computer has a temperature control function, the fan operation is intelligently adjusted according to the actual needs of the fan control system, and if the set temperature is not reached, the fan will not rotate. Stupid hood.

At least there are three ways to know:

1. If the CPU fan does not rotate, it will not take long for the CPU to crash or automatically restart due to high temperature.

2. Use Master Lu and other tools to detect the temperature of hardware such as CPU, if the temperature rises quickly and is abnormal than usual, you should suspect that the fan is not rotating or the speed is too slow.

3. The most intuitive way, of course, is to open the chassis, then turn on the machine, and directly observe whether the CPU fan is turned around.

The computer is just a fan turning, the display does not respond, there must be a problem with the computer hardware, it is best to use the replacement method to eliminate the problem, judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

1.This is usually found in the Advance Setup option in the BIOS.

If not, see if there is a PC health status? Among them, the CPU Faneq Speed Control is the fan speed regulation, and selecting Enabled is to turn on the speed regulation function (if there is no CPU Faneq Speed Control, it may also be CPU Fan Control By, in short, it is the option of fan adjustment, which is generally an option with the word FAN,).

2.Go to BIOS---Power---Hardware Monitor --- set the CPU Q-FAN Control option to Enabled. The CPU Q-Fan Profile option will appear.

When set to [Optimal], the CPU cooling fan automatically adjusts the fan speed according to the temperature of the case. If it is set to [Silent], the CPU cooling fan will run at the lowest speed for the premise of quietness, and if it is set to [Performance], the CPU cooling fan will run at the highest speed for the premise of cooling performance.

3.Install Master Lu, open Master Lu, and you can see the fan speed inside.
