Therefore, the fan slot 14 is a general specification of the fan; The fan is disposed in a casing (not shown) of a computer (not shown). The communication port 20 is electrically connected to the computer to communicate with the computer and receive the temperature signal transmitted by the computer, in particular, as a communication program between the software program in the computer operating system and the microcontroller 18, the communication port 20 is USB2. 0, USB3.0, microUSB and other specifications of the connection; microphone 16 is a micro-microphone, used to measure the volume signal inside the chassis, the noise inside the chassis is mostly caused by the fan, the microphone is similar to the decibel meter, can detect The volume in the casing reaches a number of decibels, but can also be other units that can represent noise; the microcontroller 18 is electrically connected to the fan slot 14, the communication port 20 and the microphone 16, and a database is provided inside the microcontroller 18. (not shown), the database includes the results of detecting the temperature and volume caused by different fan numbers, fan models, fan speeds and heat dissipation structures of different central processors, and has an affordable temperature. And one of the preset values for the volume, After receiving the temperature signal and the volume signal, the microcontroller 18 compares it with the database to determine whether the temperature or volume value exceeds the preset value, and any one of the temperature or volume values exceeds the preset value. At the time, the microcontroller 18 sends a control command to control the speed of the fan or turn the fan off, or to provide a plurality of control options on one of the computer screens (not shown) for selection.

In the present invention, the substrate 12 can be inserted into a motherboard (not shown), electrically connected to the motherboard, or the substrate 12 itself is a motherboard. When the substrate 12 itself is the motherboard, the fan state control device 10 is a module on the motherboard. In the embodiment of FIG. 1, the substrate 12 is a separate substrate independent of the motherboard. Therefore, a power socket 22 is required. The power socket 22 can be a SATA slot or a Molex connector. a slot or the like is electrically connected to a power supply (not shown) of the casing through a power cord (not shown), and one end of the power cord connected to the power socket 22 is a SATA or Molex connector specification, and One end of the connection power supply is a cylindrical DC power connector, and the power supply of the substrate 12 is provided by the power supply for the fan slot 14, the microcontroller 18, and the communication port 20 on the substrate 12. When the substrate 12 is a separate substrate, the communication port 20 is electrically connected to the motherboard to receive the signal of the computer. If the substrate 12 is the motherboard, the communication port 20 is a processor other than the fan state control device 10 ( The figure is not shown. The processor is used to detect and calculate the temperature of the motherboard. Therefore, the communication port 20 is connected to receive the temperature signal.

In particular, a temperature detecting software can be installed in the computer, and the temperature detecting software detects the temperature signal (temperature value) of at least one central processing unit and at least one display card on the motherboard, or some hosts on the market now. The board has the function of detecting the temperature of the central processing unit and the display card. Therefore, the temperature signal can be detected by the motherboard and then transmitted to the microcontroller 18 through the communication port 20.

The database is established through actual testing, resulting in different fan numbers and speeds. Record the different volume results. During the test, the volume and volume of the fan configuration caused by the maximum and minimum, the CPU (CPU) temperature and the display card temperature (GPU) caused by the fan configuration are the highest and lowest, and the volume caused by the fan configuration. The size and temperature results are the best (the most two, the temperature is not high and the volume is not large). The software part has obtained the data of the central processing unit and the display card (for example, the information provided by the manufacturer) through the public and existing database, so that the temperature changes of the central processing unit and the display card can be measured. In addition, different cabinet configurations (traditional configuration or the entire upside down), central processor heat sink structure (air-cooled or water-cooled), display card fan specifications (Blower Fan or non-public version card used in the public version) Axial Fan) will also be one of the different requirements of the configuration, so in the database will be tested according to the configuration of the different parts to establish a fan state control device that can provide each user to use this creation , can be based on the internal configuration of their own chassis for comparison database.

In the established database, when the user wants to use the fan state control device of the creation, the corresponding software program is installed first, and the software program guides the user to the chassis configuration and the heat sink of the central processor. Type, type of card fan, and location of fan installation and options for air intake or exhaust. After knowing the user's correct configuration, the software can inform the user that there are several options to apply in this configuration, which must include a minimum temperature configuration, a minimum volume configuration, and a temperature and volume balance. The user can decide which configuration to choose. The software itself also has a test program that helps users test the results of different configurations, and each user's test results can make the database more complete.

In the above, the database further includes a preset value of the temperature or the volume value. When any of the values of the temperature or the volume exceeds the respective preset values, the microcontroller 18 again provides the lowest temperature configuration. Control options such as the lowest volume configuration and temperature and volume balance settings are available on one of the computer's screens. For example, when the temperature exceeds the preset value, the temperature The lowest configuration may be to adjust the speed of all fans to the maximum; when the volume exceeds the preset value, the lowest volume configuration may be to minimize the speed of all fans, or directly turn off all fans, when the computer is not executed In a computationally intensive program, it is practical to turn off all fans, and the temperature and volume balance configuration can be half-closed or a few fans turned off, causing the volume of the fan to drop, while the fan continues to operate and dissipate heat. Keep the temperature at the preset value.

In the above, the microcontroller 18 can set any of the lowest temperature configuration, the lowest volume configuration or the temperature and volume balance configuration to a preset option when the temperature or volume exceeds a preset value, for example, the temperature exceeds a preset value. In the configuration with the lowest startup temperature, the volume is higher than the preset value to activate the lowest volume configuration. The three options can also be displayed on the screen, manually selected by the user, and even more, the user is outside the three options. The fan can be advanced and the fan configuration can be changed to suit different conditions.

Some users now install a light bar on the case for the appearance of the host to emit a flickering effect or a different color of light. However, the lighting effect of the light bar needs to transmit a control signal through the computer, so the light bar has a signal line. The fan state control device 10 of the present invention further includes at least one expansion slot 24 disposed on the substrate 12 for plugging in, if the motherboard does not have an extra slot. At least one light bar (not shown). The microcontroller 18 receives the control signal of the motherboard about the light bar to control the lighting effect of the light bar, and can also control the switch of the light bar according to the temperature signal, instead of just controlling the fan switch, for example, when the motherboard When overheating, if all the fans have adjusted the speed to the maximum or cannot lower the temperature to the preset value, the best choice is to control the light bar to close because the temperature has dropped to the temperature because the CPU or the display card cannot be turned off. After a gap in the preset value, the microcontroller 18 can restart the light bar.

FIG. 2 is a schematic diagram of another embodiment of the creative fan state control device 10. base The board 12 includes a plurality of fan slots 14, at least one microcontroller 18, at least one communication port 20, and a power socket 22.
