Regardless of the version, BIOS Setup hasmany settings and options that are responsible for the state of the computer and its components. Among them there is a function responsible for the cooling system of the processor, called CPU Fan Control.
This option is responsible for intelligentfan speed control. It reduces its rotational speed during idle time and low PC load when the operating temperature of the processor drops significantly.
Enabling this feature has a positive effect onnoise level of the cooling system, and in some versions of the BIOS allows manual switching between intelligent control and user mode. The latter implies the appointment of the number of revolutions of the fan as a percentage of the maximum allowed by the owner of the computer.
There is also a CPU Speed Fan option thatdisplays the current rotation speed of the CPU cooling system. In some cases, indicators are accompanied by color highlighting of information: blue accompanies the normal value, red - reduced.
However, warnings often go wrong when using more modern silent cooling systems. In this case, it is better to disable fan speed control.
This error message appears whenTurn on the PC at the initial stage of loading. It signals a malfunction in the operation of the CPU cooler detected by the BIOS when diagnosing system parameters.
In general, the problem can be circumvented without solving by clickingthe key indicated in the notification, however, this will have to be done each time you restart or turn on the computer, which is somewhat inconvenient. Therefore, you will need to understand in detail the causes of the error.
The most common source of the messageCPU Fan Error are incorrect BIOS settings. Sometimes this result is reset to factory settings, if the cooler is connected to another connector, which is not controlled by the input-output system, or if the PC has a long service life.
In the first case, you need to switch the cablecooling system to the desired connector and set the CPU Fan Speed to Auto. If this procedure cannot be done, then the monitoring system needs to be turned off, as erroneous warnings will not stop.
If the matter is in the age of iron, then replacing the BIOS battery or setting the maximum fan speed can help, but this will significantly increase the noise level.
Иногда ошибка, связанная с CPU Fan (что это, было written in the section above), occurs when the rotational speed of the cooler is manually changed by the user himself, to reduce the load on the cooling system. To get rid of the problem report, you need to return the value of the speed parameters to the original one or enable intelligent control of the CPU cooler.
If the user did not change anything in the cooling system settings, reset the BIOS to factory settings, as they are often optimal for PC to work properly.
The above method may help, however sometimesthe root of the problem lies precisely in the hardware, and not in its software component and the failure in the parameters of the CPU Fan option. Thus, if the BIOS manipulations do not help, you should check whether the cooler is working at all by opening the system unit when the computer is turned on.
If not, then you need to find the cause of this fault. It may be:
Если с настройками BIOS всё в порядке, система the cooling is OK, but the error message is still present, the sensor that keeps track of the fan speed may be faulty. Its replacement is made in the service center, and in case of unwillingness to spend money, the cooler speed monitoring system is simply disconnected.
As mentioned above, the problem can beignore with workable equipment. To do this, you will need to deactivate the cooler speed control service in the BIOS, so that during each boot you do not press F1.
Start better by turning off the system scancooling in the Power section (or close in meaning). The names of this function may differ slightly, but they can always be found by the phrase CPU Fan or Speed Fan, almost always present in the name. Next, the parameter will need to set the value Ignored or N / A.
If you cannot find such a function, you canjust turn off the request to press a certain key when it detects any errors during the download. However, this option is suitable only for fully functional equipment, so you should not resort to the instructions described below if the cooling system has not been tested.
So, to disable this option, you shouldgo to BIOS and find the tab that is responsible for selecting the method of bootstrapping the OS and setting its parameters. The names may vary depending on the version of the I / O system, but usually they contain the word Boot.
Then you need to find an option called Wait for F1 If Error, which you need to disable by setting its value to Disable. After this setup, you need to save and restart the computer.
If you follow this instruction correctly, the errorCPU Fan Error will no longer disturb and take extra time when booting the system until the next reset of the BIOS settings. However, if there is no such option in the existing implementation of the I / O system, and all the above methods do not work, then there is no way to get rid of the problem without replacing the motherboard.
