Description of the Invention: [Technical Field] The present invention relates to a fan control technology, and more particularly to a fan control system and method for controlling a cooling fan used for different types of heating elements. [Prior Art] According to the 'Central Processing Unit (CPU) is one of the core components that are indispensable when the computer is operating. Because the central processing unit operates at a high operating frequency, it will generate high temperatures during operation. In order to stabilize the effect of its fast calculation, and to avoid the central processor from affecting its working efficiency due to high temperature or burning for high temperature, it must provide heat dissipation measures. In the early days, the heat sink used in the computer's central processing unit mostly used a heat sink structure or a thermal grease to provide a divergence: a common fan structure was developed due to poor heat dissipation. With the advancement of technology, the central processor has been developed to i〇〇GHz, and then, the high-frequency GHZ and above have been developed. The electronic circuit laid in the 7 CPU components is more detailed, almost In the small area of 3~4 gossip right H v thousand square A knife, that is, there are hundreds of thousands of logical operations crying in the mouth of the mouth, ^ millions of logical operations crying. By ^= layer: people's area The sum is more often proportional to the calculation frequency, also,;, CP: its: the heat generated by 峨 and the heat generated by the heat, so the CPU does not have the higher frequency, the heat generated is even more amazing, now at the same time The package II consumes two powers, and the escaping of it has become a solution to the CPU heat dissipation problem: 2: 2: The heat sink has been shown, and the central processing 々IL 八,,, ° configuration is as shown in Figure 1. 1 〇 上 方 叹 叹 叹 叹 叹 Π Π Π , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The fin structure is used to transmit the heat generated by the central processing unit 1 to the whole of the battery, and then through the group. The cooling fan A on the heat sink 11 blows off the hot air, and finally discharges the hot oxygen through the heat dissipation holes (not shown) on the casing to the outside of the casing for heat dissipation. 'Because, because the central processor's execution capability is so fast that the temperature will also rise sharply when the central processing operation is full, the temperature of the surface of the inner device will be as high as 100 degrees Celsius. Above, at this time: timely enhance the heat dissipation performance by increasing the fan speed. At this time, the ::fan: directly in the high-speed operation state, it will inevitably consume a lot of moon b and shorten its service life, and because of the fan The faster the speed, the resulting noise will not be able to meet the computer user's need to reduce system noise: Wentian central processor is not in full-load computing processing conditions or when the ambient temperature is low, there is no need to let the fan at full speed. Operation; job is, that is, according to this, the type of fan head is automatically changed according to the temperature of the central processing 11 . This is generally done by first detecting the temperature of the central processor by temperature sensing. A pre-set fan operation control form content to enable the fan to operate in an appropriate working state, so that the cooling fan is in the most appropriate working stateHowever, in the above practice, the fan operation control form can only be applied to a specific model or series of central processing units, for example, central processing with AMD's Athlon 64, Athlon 64 FX and Athl〇n 〇pter〇n models. For example, if there are different fan operation control forms, if the same fan operation control form is used, the fan 18746 6 1283807 2 will be misaligned, and then the fan will not decelerate when decelerating, or should There was no acceleration during the Huaihe River, and it caused problems for the computer motherboard manufacturers and the users who had upgraded the central computer. In view of this, how to provide a fan control technology that can be applied to different types of heating elements (such as central processing) is an urgent problem to be solved in the industry.

As shown, the fan control system of the present invention 8 18746 1283807 • f 2 is used to control the operation of the heat generating fan. In the present embodiment, the operation of the heat-dissipating fan used in the heating element is as follows: In the following embodiments, the cooling fan system of the present invention is applied to the central processing unit (CPU). Political, working, but not limiting the scope of application of the present invention. As shown in Fig. 2, the fan control system 2 of the present invention includes a module 22, a selection module 23, and a control module 24. ) 'The type of the heating element to which the plurality of heating elements belong and the fan operation corresponding to the two categories ^ (ie different models or different series) = = example = the fan operating parameters are not the same as the production of Athl〇n 64 The temperature calculation method of Athlon 64 FX and Fenghu = ΡΓΓ and the corresponding parameters of different temperature values are different, and it is easy to say that they are not in the category of fan operating parameters (4) 3 :: (f is the heating element) corresponding to the cooling fan speed; when the operating parameters of the fan are stored in the control form to the cooling fan to the temperature threshold corresponding to the temperature, the speed of the hot fan is the coffee rotation :没有:?

The fan operating parameter is stored in the data repository 21 in a control form, and then proceeds to step S2. In the step S2, the detection module 22 detects the member of the central processing unit. In the embodiment, the detection module 22 transmits the input and output system through the computer motherboard (Basic Input 0utp). 〇m System;m〇s) The detection program at the time of booting is installed in the central processing unit of the computer motherboard, and then proceeds to step S3. 18746 11 1283807 In step S3, the selection module 23 selects the fan operation parameter corresponding to the category of the center (4) in the database 21 based on the detection result of the detection module 22, and proceeds to step S4.
