Mining machinery to 4000 fan

1. It's better not to adjust it. The bearing of the fan is worn. If the speed is lowered, the heat dissipation will be poor, which will affect the CPU life. The gain is not worth the loss. It's better to change a fan.

2. Hello LZ, there is no need to worry about this situation. Why? Because LZ you use is AMD's largest heat Yilong series of 4-core CPU, because its heat is very huge, so of course, the faster the CPU fan turns, LZ must not turn down the number of revolutions, because it is easy to cause the CPU burn, think about it, the fan turns more than 4000 revolutions, the CPU temperature is 50 degrees, and then lower it will really burn the CPU, I hope the above can help LZ~

3. It's not that the fan is broken, but that the main board has the function of intelligently adjusting the fan speed. The higher the temperature is, the faster the fan speed is, so as to achieve the purpose of rapid cooling

generally, the rotating speed of the original fan is relatively high, so the noise is high. You can consider changing a suitable radiator with better silence.

4. It mainly depends on whether your fan has four wires. If it has four wires, the motherboard will adjust the speed of the fan according to the temperature of the CPU. 4000 rpm is within the adjustment range. If it's just a three wire fan, there should be something wrong with the fan.

5. You can turn down the CPU voltage.

6. Dear users
Hello, I suggest you send it to the local service station to check it for you

in addition, if it is a win7 system, the power management software can be installed to set the power cooling strategy of the machine to passive. When the temperature of the machine is high, the fan speed increases
open the power icon in the lower right corner of the desktop, then open the power management software, switch to the advanced settings, power scheme, and then find the advanced settings in the lower right corner. The processor cooling strategy is set to active

we look forward to your satisfactory comments, thank you for your support to Lenovo, and wish you a happy life!

7. 1. When the CPU temperature is too high, the fan can only rotate at high speed in order to rece the temperature
2. The temperature control of the main board doesn't work, and it is always in high-speed motion
check these two points first, the first one is more likely
however, the fan speed is not so high now, so it is recommended to replace the radiator with a better one.

8. Of course, the noise of the CPU fan is very loud at 4000 rpm. Nowadays, the motherboard is generally equipped with automatic temperature control technology. When the CPU temperature is low, it is about 1000-2000 rpm. If the temperature rises, it will automatically rise to more than 3000 rpm. Solution 1. First, determine which component is responsible for the noise. For example, the video card power supply, CPU chassis, fan may cause damage, and replace the one that is damaged. 2、 If it is a CPU fan, check whether the automatic temperature control is turned off in the CMOS of the motherboard (check the fan speed and temperature). 3、 Remove the CPU fan to see if the cooling paste between the heat sink and the cou is dry. If the CPU temperature is too high, it will cause a lot of problems, such as restart, slow running speed and so on.....

9. The noise may be e to more st in the case. Open the case with a hair dryer and brush it with a soft brush. If the temperature is too high, go to the place where the computer is repaired in the computer city to get some silica gel, and apply it between the CPU and the fan (that's to help you transfer the temperature of the CPU to the fan). First remove the fan, and then apply silica gel on the back of the CPU. Clean the st of the fan
