Boot prompt CPU Fan error How to do?

Computer boot will appear CPU FAN ERROR, press F1 to RESUME, also accompanied by the ring 3, 4 sound, this is how to return? This phenomenon lasted six months, has been unable to find the reason, but as before, but also playing computer, feel no impact, but to enter the computer must press F1, What is the cause of this problem?

CPU FAN error means "Central processing unit fan error", popular speaking is the CPU fan failure.

This problem can be resolved in the following ways:

If the CPU fan has been moved, check to see if it is plugged in at the wrong port.

Can see on the motherboard, will find two CPU fan power connector, may be installed, the wrong answer. The interface to the other above, try, if it's okay, it means that my inference is not wrong.

If you have not moved the CPU fan socket in the motherboard, you should either turn the CPU fan off in the BIOS or the CPU fan is damaged. Boot to see if the fan is normal, if the fan is normal, that is the sensor is broken. Turn the CPU fan alarm off inside the BIOS, can be used normally, if the CPU fan is broken or its power cord off, causing your motherboard to start when the CPU fan detection can not detect, carefully check, if broken on the change, or add grease, better than that lubricating oil, Remember to use high speed grease for bearing.

Recommended to check your CPU fan plug in the motherboard on which fan socket on it? It should be on "CPU FAN" or "FAN1", you plug in other such as "System FAN" or "Fan2", although the fan can rotate normally but will appear you say that hint.

If the fan socket you have not moved, recently this situation, it is your CPU fan 3 of the line has a broken (test wind speed of the root), or fan internal circuit on the speed circuit is broken, at this time to change a new fan can be resolved.

If you change the new fan still prompts, it is your motherboard on the fan control circuit is broken, can only repair.

In the tip of the "CPU FAN Error" you press F1 to jump over, as long as you visually your fan speed fast enough to touch the heat sink is not hot, there is no problem, will not burn the CPU and motherboard.

Additional needs to be added are:

1, the fan wiring error. Because most of the motherboard has a graphics fan interface, CPU fan interface, and some also have the system fan interface, if not received CPU fan will not be aware of the CPU fan, reconnect the line to the CPU fan interface can be. Now most of the fans are 4 stitches, and some motherboards are 3-pin interface, the top of the needle should be empty out.

2, the fan speed is too low. This fault occurs mainly after the general time is used. Because the fan works in the harsh environment, inhalation of excessive dust, causing the fan to move to inflexible. Do some cleaning, grease (preferably transformer oil).

3, the fan does not turn. Either the fan motor is damaged or the sensor is damaged, and the failure can only be changed to a fan.

4, the BIOS is not perfect. If the above 3 cases are excluded and the problem is not resolved, you can use the following methods:

A, the first boot in the BIOS is changed to hard disk boot. This problem occurs when you start the disc and there is no installation disk.

B, in the BIOS first to prohibit the software, and then in the CPU FAN speed, change n/A to Disabled or ignored
