Hello everyone, Lin Fei to answer the above questions, how to buy cpu fans, cpu fans many people do not know, now let's take a look!

1. As we all know, the most important thing in a computer is CPU. When the computer is in use, the CPU needs to dissipate heat, so there will be fans on it. Some people say that the CPU fan in their computer starts to work normally, then slowly slows down or something else happens. How normal is the speed of the CPU fan? Let's learn:

2. Check the CPU speed:

3. To know whether the CPU fan speed is normal, we first need to know what the fan speed is when our computer is in use. You only need to download some tools such as Master Lu, hardware Master 360, and you can automatically check the CPU fan speed for you.

4. What is the normal CPU speed?

5. In general, it is most appropriate for a computer to keep the CPU temperature below 65 degrees during the use of the computer. Some people think that the faster the fan rotates, the better. However, in fact, the speed of the CPU fan is determined by the calorific value of the computer CPU. There is a thermal sensor on the CPU, and the speed of the CPU fan varies at different temperatures. Generally speaking, if the CPU temperature is normal, the fan speed is about 2000-2500 rpm. Some people play high-profile games. The temperature of the CPU will rise / min, so the CPU temperature may exceed 60 degrees Celsius, and the CPU fan will reach 5000 revolutions, but in this case the fan is normal. Therefore, the specific value of fan speed does not have an accurate value, mainly related to the environment and user demand, not the higher the speed, the better.

6. What if CPU slows down?

7, the reasons for the slow speed of the fan: first, check whether the computer CPU fan has been used for too long and has not been taken apart to clean up the dust, resulting in the accumulation of too much dust, which makes it difficult for the fan to rotate and slow down. It is recommended to clean the computer hardware regularly, not only the fans, but also other hardware and dust regularly. Dust does great harm to computer hardware.

8. In addition, if the CPU fan is loose when it is not installed, it will also cause the fan to slow down. All recommendations are to be careful when installing and removing CPU fans.

9. Cpu speed adjustment

Step 1: to use the intelligent CPU fan control function, you must first set the "CPU fan control mode" in the motherboard BIOS to intelligent.

Step 2: no matter which CPU model of LG A775 is used, it is recommended that the fan start temperature of CPU be set at 24 ~ 35. If the initial temperature of the CPU cooling fan is set too high (such as above 50) and the start-up PWM value is set too low (such as the 800rpm or so PWM value), the heat generated by CPU will not be discharged in time, resulting in overheating and death.

Step 3: the setting of CPU fan off () is very useful after the system enters S1 standby state, because after the system enters S1 standby state, the CPU load will be reduced to a minimum, and the CPU temperature will also drop (usually only about 20). The heat generated by CPU can be effectively discharged only by the heat sink, without the need for a cooling fan. Therefore, it is recommended that you set the value of this item between 16 and 20.

13, step 4: for the CPU fan full speed () option value, it is recommended to be set in the range of 60 ~ 64 (can not be higher), because most LGA775 interface Pentium 4 or Cy Young D's highest normal operating temperature is about 75, if CPU works for a long time in more than or very close to this limit, it will cause irreparable damage to CPU.

Step 5: make several attempts when adjusting the startup CPU value, because the ratio of the speed to the PWM value of different PWM fans is different. However, it is recommended that the initial speed of the CPU fan be adjusted above 1100rpm (some brands of motherboards will issue a zero-speed alarm or shut down automatically when the CPU fan speed is lower than 2000rpm, then we can turn off the CPU fan speed alarm function), the PWM value is roughly between 15 and 35.

Step 6: the step size of 6:Slope PWM is usually set to 16 PWM /

What is the normal CPU speed? Through the introduction of the article, I believe we all know clearly that the speed of the CPU fan is very important and has a great relationship with the life of the computer CPU, so we should pay attention to it.

At the end of this article, I hope it will be helpful to you.
