Is there any way to adjust the starting temperature of the fan?

There are two types of this: configurable (intelligent management) and non-configurable (hardware control) type, which are explained below according to intelligent management

1. In the BIOS

Set the CPU temperature and start the fan speed in the hardware monitoring (select del, f1, f2, and f8 according to different models of notebooks when starting the notebook.)

button to enter the BIOS, then find the Hardware Monitoring option and select CPU Fan Monitoring to set the CPU to 40°C

fan 20% 50°c 75% 60°c 100%）；

No matter which setting can only be a relative setting, such as the temperature exceeds a certain level, the setting is invalid The system will protect the CPU from directly shutting down or adjust the fan to 100% speed, (some machines do not have hardware fences, and there will be a warning when setting, otherwise the hardware will be damaged because the setting is too low!) ）

Here's how to set it up:

1.Select System & Security in Control Panel.

2.Select the Acacia Fiber Power option.

3.Select High Performance Select a more lead guess plan setting.

4.Select Advanced power settings.

5.Select High Performance Select the sub-option to expand to make detailed settings.

6.The heat dissipation mode is divided into active and passive, the active mode means that the speed has been maintained at a relatively high speed, and the passive mode is the vertical balance that only accelerates the speed when the heat of the CPU is high.

The following describes how to adjust the speed of the computer temperature control fan.

On motherboards that support speed regulation, there are two types of CPU fan power supply interfaces, one is that the motherboard can adjust the fan speed by controlling the power supply voltage, and the other is non-adjustable. After the CPU fan power supply is connected to the adjustable speed interface on the motherboard, you need to enable the CPU fan intelligent speed adjustment function in the motherboard settings to realize the automatic adjustment of the CPU fan speed. The specific adjustment method is as follows:

1. Press del to enter BIOS when booted;

2. After entering the BIOS, look for PC Health in the left column, focusing on the word Health;

3. Enter the list page, automatic fan control (or the option with a similar name);

4. Turn this option on, and you can set the CPU fan to automatically adjust the speed.

To put it simply, whether the fan on your CPU cooler can regulate the speed, you only need to see how many pins the power plug it provides, if it is 4 pins (in addition to the positive and negative poles of the power supply, there are also two more pins for speed regulation and speed monitoring), you can achieve intelligent speed change, if it is 3 pins (in addition to the positive and negative poles, the speed monitoring pins are added), it is not necessarily.

Here is the principle of speed regulation of 4-pin fan and 3-pin mesh fan. First of all, for the 4-pin fan, the temperature is sampled through the temperature monitoring unit inside the CPU, and then the pulse width modulation of the electrical signal output to the fan is carried out through the PWM (pulse width modulation) chip - the essence is to change the effective voltage and current output to the fan, so as to control the speed, the advantage of this control is that it has nothing to do with the design of the motherboard itself, the temperature sampling signal is accurate, and the stepless speed change of the fan can be realized.

The 3-pin fan itself does not have a speed regulation function, and the motherboard needs to provide the corresponding function to achieve it. For example, the output voltage corresponding to several speeds is preset in the BIOS, and the output voltage is determined according to the cup temperature sampled by the temperature probe on the motherboard, so as to realize the speed regulation of the fan. In this way, although the speed is also automatically adjusted, compared with the speed regulation of the 4-pin fan, the sampling temperature is not accurate enough, and the second is that the speed regulation can only be changed by gear, and the flexibility is insufficient.

Of course, if you have strong hands-on ability, you can also give a 3-pin fan a governor in series (tens of yuan a) to manually achieve stepless speed regulation.

No way, I installed a fan governor to control the wind speed!

Summary. In general, the starting temperature of the fan intelligent control is 25, but it can also be adjusted according to the user's needs.

Excuse me, but please go into more detail?

The starting temperature generally refers to the set temperature of the fan intelligent control system, which refers to the temperature at which the fan starts to run. Under normal circumstances, the starting temperature is set at 2-3 degrees or more of the room temperature, which can ensure that the fan starts to run when the room temperature reaches the set temperature, so as to achieve the purpose of energy saving. If the starting temperature is set too low, it may cause the fan to start running before the room temperature reaches the set temperature, thus wasting power.

In addition, if the starting temperature is set too high, the fan may not start running when the room temperature reaches the set temperature, which will affect the control of the room temperature. The solution to this problem is to reasonably adjust the initial temperature of the fan intelligent control system according to the change of indoor temperature, so as to achieve the purpose of energy saving. Personal Tips:

When adjusting the starting temperature of the fan intelligent control system, it should be reasonably adjusted according to the change of indoor temperature to achieve the purpose of energy saving.

Tool: Computer.

1. Open the Start Menu Zhiliang Stool, and click the [Start Windows System Control Panel] menu item in turn.

2. Click the [Power Options] menu item in the window.

3. Click the [Change Plan Settings] shortcut link on the right.

4. Click the [Change Advanced Power Settings] shortcut link.

5. Click the "Processor Power Management" menu item in the window, and click [Settings].

6. Set it to [Passive], and the CPU will automatically adjust the speed of the fan according to the temperature.

To see if the motherboard supports intelligent temperature adjustment, if it is possible, go to the power settings of the BIOS or set it in the hardware detection (the fan pin of the CPU must be four-pin (the adjustment is effective)).

Pressing the Delete key will take you to the BIOS interface, and adjust it to "Advanced" through the arrow keys of the keyboard"press enter and click on "h w monitor.""option to enter;

Go to "h w monitor.""After the options, you can see the relevant data of CPU running, you can see that CPU Fan Mode Setting is currently in full on mode, click the "CPU Fan Mode Setting" option and press Enter;

At this time, the relevant settings of "CPU Fan Mode Setting" will be, select the last "Automatic Mode", after selecting the automatic mode, the CPU will adjust the speed of the CPU according to the current temperature, and finally press Enter, press F10 to save, and it will be much quieter immediately after restarting.

The case fan seems to be 3-pin, so it can't be automatic.

Isn't the PWM port connected to the CPU fan port fully automatic?
