Parameter Selection of Computer Cooling Fan

Back to list Release date: Dec 14, 2018

      As we all know, computer cooling is mainly the CPU, followed by better high-performance discrete graphics cards.


      At present, the DC fans sold in the general computer market are 12V, with power ranging from 0.2 to 3W, so the power needs to be based on your CPU calorific value

To choose. In particular, we should not overemphasize high power, but only match the power of the CPU itself.If the power is too high, no

However, the cooling effect is not enhanced, but may increase the workload of the computer and ultimately shorten the life of the CPU and fan.


      The main performance of the cooling fan includes the following aspects:rotating speed, fan blade shape, fan blade angle and bearing system. In general, on the radiators instructions

All indicate the speed of the cooling fan.Generally speaking, 30 % of the cooling effect of the radiator depends on the speed of the fan, but the higher the speed of the fan, the better.


      The correct fan speed should be determined according to the calorific value of CPU, and the speed selection of cooling fans of different specifications should be differentiated.The basic principles are:1

On the premise of producing the same air volume, the higher the speed of the fan, the lower the noise. Generally, the rotation speed between 3500 and 5200 rpm is relatively normal

Regular.   2.The greater the power, the stronger the fan wind, and the better the heat dissipation effect. The power of the fan is directly related to the rotational speed of the fan, that is to say

The higher the speed of the fan, the stronger the fan will be.


      Generally speaking, there is a wind direction sign on the cooling fan.The left-to-right arrow indicates the direction of the fan rotation and the up-to-down arrow indicates the direction of the wind. The fan is on

Put it on the left and right inside to let the wind out of the back of the cabinet. The fan is placed up and down.The fan should be placed over the video card, excluding the wind that cant blow to the back of the video card.No.

However, dust will accumulate on the back of the video card, and failure will occur if there is too much dust. Press-down radiator, blowing in the direction of cooling fan.


      Taiwans San Ju motors have been focusing on the heat dissipation industry for 30 years.Welcome to come to your own special heat dissipation fan.
