V. Description of the invention (1) [Technical field to which the invention belongs] Method for making noise value Application The present invention relates to a design process for controlling the fan speed control. [Previous technology] Presentation: 2: The working frequency of the central processing unit is 1 liter, and the original 133MHz has been developed to the fastest 2 5GHZ now. It took several years. • Of course, the current mainstream central office — Li Cui 5 Η: 18 micron or even 13 micron process technology, but because the device is composed of many transistors ... In the amount: Central processor is much higher. Nowadays, 1GHz: = in order to achieve a power of more than 40W, and the central processor of pe above 2GHz consumes almost 70w of power, so high 1: the central processing caused the heat of the central processor Surge. In particular, 3 ', direct good cooling measures can not be taken in time. If there is no heat energy to take away in time, a large number of CPUs generated inside the CPU will age or even destroy, resulting in a fan. For the entire The computer's heat dissipation and thermal effect are good, and the 'Follow CPU's working frequency' ^: 2 keys. Therefore, many manufacturers and play ";: its heat is drawn back to the fan speed or more fans are installed," and everything is increased or the number of fans is increased to raise the wrong The higher the speed of the fan, the more the number of fans; but with: Because: flat: why the fan's dispersion = will also take everything else, it is the current design of the fan design 564291 Amendment _ Case No. 91132876 (2) To the extent that the noise value generated when the fan is rotating is the following: 籀 The following two types: (1) Improve the fan bearing (2) Reduce the wind 4 entanglement, large type, including t it t two According to the fan bearing classification, the fan can be divided into :. ϊ;! ΐ belong to sliding friction and rolling friction, respectively, because of the two values, but their technology has not yet been developed to be low in yak and the acceptance of noise wood generated by friction is low. The cost is relatively south, so it stands up in the market ::? Method-Reduce the fan speed. This method is an obvious method for π wind;:, 疋. # ，， ： Lower the fan, the value of the arm sound generated by it is fixed at $, 'Cause:,: The speed of the heat source can be proved at a fixed speed: The value is too large, the body can change the wind genus, although the person can adjust the wind Household M again. And another method with variable rotation and temperature protection; wind, 1!

Then, draw the temperature of this heat source and Relation diagram of the rotation speed of the fan module, and the relation diagram of the rotation speed and noise of the fan module. ^ Next, obtain a temperature control graph, and draw the temperature control graph at the degree of f of the heat source and the rotation speed of the fan module. On the relationship diagram; and draw the corresponding speed interval and temperature interval of the allowable noise value set by the person who set the juice in the graph; the temperature and speed noise interval are designed by the designer according to the customer's needs to check the relationship diagram value Corresponds to the graphic design indicated by the designer until it falls into the range, and becomes the fan. In order to understand, the intersection of the temperature control graphic and the speed is the interval and setting work.
