The invention relates to a multi-fan identifiable system and a control method thereof, in particular, using a plurality of fan specification parameter tables, at least one fan and a discriminating device to increase replacement fan Convenience. '[Prior Art] At present, the mainstream CPUs use 130 nm nanometer or 90 nm process technology, but because the high-speed central processor is composed of many transistors, the degree of heat is higher. In the past, the central processing unit was much higher. Today, CPUs above 1 GHz have almost tens of watts of power, and such high power consumption directly leads to a surge in heat generated by the central processing unit. Especially in the hot summer days, or in a non-ventilated environment, 'If a large amount of heat generated by the central processing unit is not taken out without good heat dissipation measures, electron transfer will occur inside the central processor'. Aging is even damaged, burned, and affects other internal parts of the computer. Therefore, a fan with good heat dissipation effect will have a significant effect on the overall heat dissipation of the computer. For example, the Republic of China Patent Publication No. 520150 discloses a heat-dissipating fan structure having a temperature sensor, the fan structure comprising: a housing, which is provided with a board, the seat board is provided with a sensor window; and a fan has a number of rounds in the center The housing is received in the housing and fixed to the seat plate; and a temperature sensor is disposed on the fan and the sensing window of the seat plate provided by the housing corresponds to the heat source to correctly detect the actual heat source The temperature of the fan is adjusted according to the temperature; once the temperature change occurs on the heat sink, the temperature sensor can directly detect the 1317465 and decide to adjust the speed of the fan. However, the above-mentioned heat-dissipating fan structure with a temperature sensor performs an extremely important heat-dissipating function 'because its powerful heat-dissipating function will relatively generate a great noise, and the more powerful the cooling fan, the more unbearable the noise level' The user has been troubled by the use of the computer. Therefore, another fan control method that combines efficiency and user comfort has emerged. For example, the Republic of China Patent No. 564291 discloses a method for controlling the noise value by the fan speed, and the method includes The following steps: obtaining a fan module; obtaining a heat source; corresponding relationship between the rotational speed value of one of the m-degree fan sets, and the corresponding relationship between the rotational speed value and the noise value of the fan module; drawing the temperature of the heat source A relationship diagram between the rotational speed value of the fan module and a relationship between the rotational speed value and the tremor value of the fan module; obtaining a temperature control pattern; the temperature is determined by the temperature of the heat source and the object The speed value of the mo group: two, and m to obtain the desired setting - the material value should be the fan module speed n and the temperature interval, and the heat source The temperature is with the fan die! And the relationship between the rotational speed values; indeed; ^ cross ^; and the temperature control graph is the temperature control sought, and the parameters of the second interval are set to minus (four). (4) The fan specification parameter table used in the fan of the temperature control graphic is required to have a fan of the brain size. If the wind source is short or considers the same - it must be used in the same batch of computers with different specifications/dimensions. Difficulties, even caused the entire batch of elegans yield:: Female, ^ caused the process of 1317465 poor or damaged and need to be replaced, because the computer can only match the original single fan, so users can only seek The fan that is identical in size to the original fan's inconvenience to the user, and if you can't find a fan with the same specifications as the original fan, and use a new fan of different specifications, then the new fan may not match the original. The fan specification parameter table 'causes the heat dissipation performance to be uncontrollable, further jeopardizing the overall safety of the computer and causing safety concerns. In the prior art, a fan of a single specification is used in the computer to match the corresponding single fan specification parameter table, and the current fan in the computer may not be provided in the case of replacing the original fan due to the process or the use requirement. A comprehensive and complete solution. Therefore, there is an urgent need to provide a complete fan system and method.
