Fans have a maximum speed, depending on their models. The full speed of ordinary fans is around 2000, because it is too fast and noisy. No matter how good the fan is, it does not rely on increasing the speed to improve the heat dissipation performance. If it is a temperature-controlled fan, it will automatically run at full speed when the temperature reaches a certain level. If it is set to run at full speed in bios, it will run at full speed regardless of the temperature, so the noise can't be controlled. If your fan is only 1000 rpm, you can't adjust it. Maybe that's it, or the broken software can't control it.
If it is a desktop, Master Lu may not have seen it correctly. Check the bios of the motherboard.
Whether it is a desktop or a notebook, we must first ensure good heat dissipation, such as whether the fan ventilation duct is blocked or not, and whether the silicone coating is in place. After confirming these conditions, if the temperature is still high, only the fan can be replaced. In addition, some desktop cpu fans have poor heat dissipation performance, such as some high-end CPUs of I5 I7 AMD. It is recommended to replace them with better fans. Some models of notebooks are in poor heat dissipation state and the cpu is hot, which is not a fault. If the hardware is in good condition, the ventilation performance can be guaranteed, and it doesn't crash or restart automatically when playing, it doesn't matter.
How to adjust the speed of CPU fan for 5 minutes
1: system high temperature warning
2: CPU high temperature warning (you now set the CPU to a 90-degree alarm)
3: CPU fan stall alarm (after startup, if the CPU fan does not turn, an alarm will be given).
4: System fan stall warning (same as above)
5.CPU intelligent fan speed control (turn off this option, the CPU fan will run at full speed with great noise, instead of intelligent speed control according to the system load. )
If you want to adjust the speed, answer: Pay the bill or multi-channel fan governor, Taobao has it, you can search it.
B: Buy a reducer and reduce the fan speed by increasing the resistance. Mute, but the heat dissipation performance will decrease.
How does the computer adjust the speed of the intelligent fan?
Cpu fan speed adjustment step 1: To enable the intelligent CPU fan control function, you must first set "CPU fan control by" in the motherboard BIOS to SMART. Otherwise, set it to "Disabled" to run at full speed.
Step 2 of cpu fan speed adjustment: No matter what type of CPU is used, it is recommended to set the starting temperature of CPU fan at 24 ~ 35℃. If the initial temperature of the CPU cooling fan is set too high (for example, above 50℃) and the starting PWM value is set too low (for example, the PWM value of about 800rpm), the heat generated by the CPU cannot be discharged in time, thus causing the consequences of overheating and crashing;
The third step of cpu fan speed adjustment: the setting of CPU fan off (℃) is very useful after the system enters the S 1 standby state, because the CPU load will be minimized and the CPU temperature will be reduced (usually only about 20℃) after the system enters the S 1 standby state, so the heat generated by the CPU can be effectively discharged only by the heat sink, and no cooling fan is needed. Therefore, it is recommended that you set the value of this item between 16 ~ 20℃.
Step 4: Adjust the speed of cpu fan: For the value of the CPU fan full speed (℃) option, it is recommended to set it in the range of 60 ~ 64℃ (not higher), because the maximum normal working temperature of most CPUs is around 75℃, and if the CPU works beyond or very close to this limit for a long time, it will cause irreparable damage to the CPU.
Step 5 of cpu fan speed adjustment: When adjusting the starting PWM value, try several times, because the ratio of the speed of different CPU fans to the PWM value is different. However, it is suggested that the initial speed of the CPU fan should be adjusted to above 1 100rpm (some brands of motherboards will give a zero-speed alarm or automatically shut down when the speed of the CPU fan is lower than 2000rpm, so we can turn off the speed alarm function of the CPU fan), and the approximate range of PWM value is between 15 ~ 35.
Step 6 of cpu fan speed adjustment: 6: The step size of slope PWM should usually be set below 16 PWM value/℃, otherwise the CPU fan will "sound like Hong Zhong" as long as the CPU temperature rises by a few degrees Celsius.
How to adjust the speed of CPU fan in win7
This problem should be caused by the power management of Win 7. As long as the power management of the CPU is set, the CPU fan can be adjusted according to the temperature to adjust the speed. See the following steps for details.
How to improve the fan speed
It will be better to dissipate heat after cleaning the dust. The fan must be slow.
The system automatically monitors the temperature, and then controls the fan speed without manual control.
The computer won't burn out, and the motherboard has a high temperature protection circuit. Once the temperature is too high, the fan has no time to dissipate heat, and the computer is directly powered off to protect it.
How to improve the speed of computer fan
Click "Start" in the lower left corner of the desktop and select "Control Panel" to open the control panel;
Select System and Security in the panel;
Select System and Security in the panel;
Select High Performance → Select Change Plan Settings;
Select advanced power settings;
Select high performance → select sub-option expansion-processor power management for detailed settings;
The cooling modes are divided into active mode and passive mode. Active mode means that the speed is always kept at a relatively high speed, and passive mode means that the speed is accelerated only when the CPU is hot.
Adjust the fan speed according to the actual situation.
How to improve the speed of win7 fan
Hello:
-1, the cooling fan of CPU is the key, but the radiator is more critical: some high-quality radiators use copper to contact CPU, and the effect is better than that of aluminum radiator.
-2. The heat dissipation silicone grease coating process of CPU is also critical. Appropriate amount of silicone grease is helpful to heat dissipation, while uneven or excessive silicone grease will hinder heat dissipation.
-3. In addition, the temperature in the chassis also directly affects the heat dissipation of the CPU. If necessary, a fan can be installed on the shell and at the position corresponding to the CPU to blow cold air inward, which can obviously increase the temperature of the CPU, motherboard and hard disk.
How to adjust the speed of computer cpu fan
Specific measures: 1, input power under BIOS, set CPUFAN mode to automatic, and restart. First, set the fan to automatic mode, and check the speed and sound after starting. If it is acceptable, it is best to set it in this medium mode. If not, then continue. 2. Set the manual mode in the CPUFAN mode setting, and the CPU fan is set between 100- 150 (default is 250), so that the fan speed will drop to 1800-2400, and the noise will be much less. However, the speed of the fan is not intelligently adjusted at this time, that is, the speed is a certain value! 3. Set the intelligent speed regulation. The target temperature of CPU fan is Valun -40, and the starting value of CPU fan is-40, that is, the intelligent speed regulation starts after the CPU temperature reaches 40-35, that is, the speed regulation stops after the CPU temperature reaches 35, and then slows down! Note: CPU temperature needs to be detected during the whole adjustment process of the fan. If it is too high or crashes, you should immediately stop changing the fan to the original default setting. If so, your fan power is too small to reduce the speed, and you need to buy another radiator.
Type I: * * * art fan control-mode setting CPU * * * art fan control is set to auto or enable (that is, the setting is turned on first), and CPU *** art fan mode is set to PWM(PWM pulse speed adjustment function is turned on).
Common motherboards, such as Gigabit BIOS (Gigabit motherboards are generally set to on by default, and the parameter is AUTO.
The second CPU Q-FAN control setting
CPU Q- fan control is set to be enabled first.
The cpu fan profile mode will appear below, and there are three modes to choose from.
The best mode allows the system to automatically adjust the fan speed according to the temperature change;
Silent mode will reduce the running speed of the fan;
Performance mode will increase the fan speed to obtain the best system cooling effect.
Players are advised to choose according to their own situation.
Q-FAN is a patent of ASUS motherboard, which is of course used on ASUS motherboard. Before 10, the default CPU Q-FAN control function of the motherboard BIOS was turned off, and now the default BIOS of the motherboard after 1 1 is turned on.
The third CPU mute fan setting
There is no PWM option in the BIOS of this motherboard, which can be set to medium speed or slow speed.
1. First set the CPU mute fan to enable. 2. It is best to set the following target CPU temperature to 50-65. 3. Finally, the target CPU speed sets the speed level.
How to adjust the speed of CPU fan in BIOS
Can be adjusted, but I think it is better not to change the default BIOS! There is an option of smart fan in BIOS. Some motherboards have only two options, (Enable) or (Disable).
This is the automatic speed regulation of the CPU fan that comes with the motherboard, but I use the option after the MSI motherboard smart fan.
That's not true. It has many temperature options. I chose it for a long time, tried it many times, and found that the BIOS was modified.
The fan speed of the rear CPU is too slow, only 1800- 1900 rpm. I was afraid of burning the CPU, so I recovered. (The BIOS sets the smart fan to D-floating by default, but there is no Enable option, but there are many corresponding temperature options). At the same time, I suggest you download some software from MSI official website to see how your CPU works.
Web page: microstar/ ... (power supply) socket
See for yourself what kind of electric shock it is. There will be corresponding tools and software downloads.
Do you think your CPU fan is loud? If so, I think it is better to buy a good CPU fan.
Be nice, after all, the speed is too slow after modifying BIOS.
I also use MSI's motherboard. I hope my suggestion will help you!
How to adjust the fan speed in BIOS?
Take dual-core Athlon 4200+, 4-pin original fan (3-pin fan does not support speed regulation) and A78GT motherboard as examples:
1: First install the CPU dual-core patch and system optimization patch, and select "Minimum Power Management" in the power management option.
2. Boot into BIOS, and select power supply, that is, hardware security configuration;
(1): Set the manual mode (that is, manual mode) in the cpufan mode setting, and set the CPUFAN between 100- 150 (default is 250), so that the speed of the fan will be reduced to 1800-2400, and the noise will be much less.
(2): Set the intelligent speed regulation, and the CPU fan target temperature value (CPU fan mode setting) -40.
CPUFAN tolerance value-03
The starting value of CPU fan is -40, that is, the intelligent speed regulation is started after the CPU temperature reaches 40.
The CPU fan stop value is -35, that is, when the CPU temperature reaches 35, the speed stops and then decreases!
Option 03 is translated into the tolerance value of CPU norm, I don't understand what it means, hehe, let a bird whisperer answer it. In both schemes, (1)CPU fan speed is a fixed value; (2) It is the intelligent fan speed regulation we are looking for.
The above is for reference only. After my adjustment, the minimum speed of the fan has been reduced to about 1 100 rpm. Of course, when the temperature rises, the speed will automatically increase. After adjustment, you can use the system stability test that comes with EVEREST software, and you can see the effect. I wonder if other motherboards support speed regulation. All I know is that AMD780 chipset can. Please refer to your motherboard manual or official consultation!
