2. What is the body speed of the slope parameter? Each manufacturer has different designs and different values.
3, * * * * The same is that the speed of the fan is fast and the heat dissipation will be large, but the fan is noisy and consumes a lot of electricity, which accelerates the aging of the fan.
4. The manually set slope parameter cannot be set too high.
5. Manual mode needs to set the fan speed parameter (PWM slope) by itself, which is mostly used for users who need to manually control the CPU temperature according to the heat dissipation of the CPU.
Extended data
Performance of computer fan
1. The instructions of the radiator indicate the speed of the fan. Generally speaking, 30% cooling effect of radiator depends on the speed of fan.
2. The higher the fan speed, the better. The correct fan speed should be determined according to the calorific value of CPU.
3. Different specifications of the fan speed selection should be different.
4. The greater the power, the stronger the fan wind power and the better the heat dissipation effect.
5. The power of the fan is directly related to the rotational speed of the fan, which means that the higher the rotational speed of the fan, the stronger the fan will be.
6. At present, the fans sold in the general computer market are all DC 12V, and the power is from 0. X W to 2. X W. power needs to be selected according to the calorific value of CPU.
7. A good radiator has no burr at the edge, no deformation of the radiator, smooth bottom and no crack, neat appearance, generous shape, guaranteed quality, and a trademark with anti-counterfeiting marks or other characteristics.
8. When choosing a radiator, you should also pay attention to the fact that the bottom of the radiator should not be too thick, and the thermal conductivity of aluminum is not very good. Too thick will affect heat transfer.
9. In addition, the guide grooves on the surface of the radiator should be dense, so as to ensure that the radiator can have a larger contact area with the air, thus enhancing the heat dissipation effect. ?
