The current CPU fan (original package) or its own purchased CPU fan has intelligent adjustment function, which can not waste unnecessary power and generate noise when the speed is too high for a long time. Increase the speed to protect the CPU temperature in a reasonable range when the computer has a high heat output. The CPU fan speed adjusts the amount of CPU fan air volume, and then adjusts the CPU temperature. The higher the CPU fan speed, the larger the CPU fan's air volume, and the lower the CPU temperature. Many students worry that their CPU fan speed can't adjust the CPU temperature very well, causing the CPU temperature to be too high and burned. Under normal application, the current CPU fan (original package) or its own purchased CPU fan has intelligent adjustment function, which can not waste unnecessary power and generate unnecessary noise for a long time, and can also be in the computer. Increase the speed to protect the CPU temperature in a reasonable range when the application of high heat output is high. Then cpu fan speed adjustment how to adjust, Xiaobian for the students to introduce the specific steps of cpu fan speed adjustment. Cpu fan speed adjustment step 1: To enable the intelligent CPU fan control function, you must first set the CPU FAN Control by & rdquo; in the motherboard BIOS to SMART. Otherwise set it to: “Disabled” is the full speed operation cpu fan speed adjustment step 2: Regardless of which type of CPU is used, it is recommended to set the CPU Fan Start temperature to 24~35°C. If the CPU cooling fan initial temperature is set too high (such as 50 ° C or more), and the Start PWM Value is set too low (such as the PWM value of 800 rpm), the heat generated by the CPU can not be discharged in time, resulting in The consequences of overheating the crash; cpu fan speed adjustment step 3: CPU Fan Off (°C) setting item is very useful after the system enters the S1 standby state, because the CPU load will be minimized after the system enters the S1 standby state, at this time the CPU temperature is also It will be reduced (usually only about 20 °C), and only the heat sink can effectively dissipate the heat generated by the CPU, without the need for a cooling fan. Therefore, it is recommended that you set the value of this item between 16 and 20 °C. Cpu fan speed adjustment step 4: For the CPU Fan Full Speed (°C) option value, it is recommended to set it in the range of 60 ~ 64 ° C (can not be higher), because most CPUs have a maximum normal operating temperature value of about 75 ° C If the CPU works for a long time if it exceeds or is very close to this limit, it will cause irreparable damage to the CPU. Cpu fan speed adjustment step 5: When adjusting the Start PWM Value, try several more times, because the ratio of the speed of the different CPU fans to the PWM value is different. However, it is recommended to adjust the starting speed of the CPU fan to more than 1100 rpm (some brands of motherboards will issue a zero speed alarm or automatic shutdown when the CPU fan speed is lower than 2000 rpm, then we can turn off the CPU fan speed alarm function), its PWM The approximate range of values is between 15 and 35. Cpu fan speed adjustment step 6: Slope PWM step size should normally be set below 16 PWM Value /° C, otherwise the CPU temperature just rises a few degrees Celsius, your CPU fan is "sound like a Hong bell". The above is the specific steps of the cpu fan speed adjustment, the steps are not common to all machines, for reference only.
