The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The invention discloses a fan speed regulating method, as shown in fig. 1, comprising the following steps:
Step S1, power consumption of a display card power supply, system fan information and environment information are obtained;
The system fan is arranged in the case and is used for discharging heat in the case to the environment.
Specifically, the system fan information includes a corresponding relationship between a system fan rotational speed and a flow rate and a corresponding relationship between the system fan rotational speed and a noise loudness. After the system fan information is finished in the process of producing the system fan, the manufacturer can perform related tests, and can acquire the data of the tests or actual tests, which is not limited by the invention.
Specifically, the environmental information includes the air density ρ and the air specific heat capacity. Generally, at standard atmospheric pressure, the air density ρ 0＝1.293kg/m3, taking into account the fan pressure inside the enclosure and the environment inside the enclosure, is typically taken to be air density ρ=0.785 kg/m 3 at an altitude of 3000 m. Typically, the specific heat capacity of air C is a fixed value, c=1005 j/kg ℃.
And S2, calculating the flow demand of the fan of the system according to the power consumption of the display card and the environmental information.
Specifically, according to the power consumption of the display card power supply, the heat required to be emitted by the display card during working can be calculated, and according to the air density and the specific heat capacity in the environmental information, the volume of air required to take away the heat emitted by the display card can be calculated, so that the flow requirement required to be provided by a system fan is calculated.
And step S3, calculating the rotating speed of the system fan according to the flow requirement of the system fan and the information of the system fan.
Specifically, according to the corresponding relation between the system fan speed and the flow in the system fan information, the required system fan speed can be calculated according to the flow requirement of the system fan.
In particular, the corresponding relation between the system fan speed and the flow in the system fan information can be obtained according to the test data of the manufacturer, or can be obtained through actual test, which is not limited in the invention. Generally, the corresponding relationship between the rotational speed and the flow rate of the fan of the system is determined according to a plurality of factors such as the diameter of the fan blades, the inclination angle of the fan blades, and the number of the fan blades.
According to the fan speed regulating method provided by the embodiment of the invention, the power consumption of the display card power supply is obtained, so that the fan speed regulation can be realized only by realizing the power feedback function of the power supply in the prior art on the premise of not specially upgrading the function of the existing main board or adding the temperature sensor, the method can be simultaneously applied to display cards of various types, and the defects of high cost and poor expansibility in the use of the high-performance display card in the prior art are overcome. By calculating the real-time flow demand of the system fan, the system fan can be immediately accelerated when the load of the display card is increased, so that the hot wind energy of the system is smoothly discharged, the problems of heat dissipation and noise of the system are solved, and the defect of high noise of the high-performance display card in the prior art when the display card is used is overcome.
In one embodiment, the fan speed regulation method further comprises:
And S4, adjusting the duty ratio of the system fan according to the rotating speed of the system fan.
Specifically, the process of adjusting the system fan duty cycle may be notified by the BIOS to the input output chip (SuperInputOutput, SIO) to execute a high power graphics card speed regulation scheme. The SIO executes a display card fan speed regulation scheme and feeds back in real time, the BIOS and the SIO work cooperatively to realize dynamic and stable regulation of the rotating speed by the GPU-12V power consumption fed back by the real-time seek power supply, and meanwhile, the SIO can perform some filtering or average value maintenance of stable regulation of the rotating speed like the temperature, so the invention is not limited to the above.
The SIO may convert the received system fan rotation speed into a system fan duty ratio according to a preset maximum fan rotation speed, and may be represented by the following formula:
Wherein Duty is the system fan Duty, n is the system fan speed, and n MAX is the preset maximum system fan speed.
For example, after the SIO converts the system fan speed into Duty, the SIO converts the Duty into a square wave signal and sends the square wave signal to the fan with the pulse width modulation (Pulse Width Modulation, PWM) function, so that the fan speed can be controlled, or the Duty can be sent to the Power chip (PowerIntegrated Circuit, powerIC), and the Power IC converts the Duty into a Direct Current (DC) signal and sends the DC signal to the fan with the Direct Current (DC) speed regulation function, or the fan speed can be controlled.
In one embodiment, the process of obtaining the power consumption of the graphics card, the system fan information and the environment information includes: firstly, acquiring power consumption of a display card power supply; then judging whether the power consumption of the display card power supply is larger than a preset power consumption threshold value or not; and finally, when the power consumption of the display card power supply is larger than a preset power consumption threshold value, acquiring system fan information. Particularly, when the power consumption of the display card power supply is smaller than or equal to a preset power consumption threshold, the system fan duty ratio is adjusted according to the preset system fan rotating speed.
Specifically, the process of obtaining the power consumption of the graphics card power supply may be implemented by a function in a basic input output system (Basic Input Output System, BIOS) of the computer, or may be implemented by an external power meter, etc., which is not limited in the present invention.
When the obtained power consumption of the power supply of the display card is equal to 0, the display card is proved to be only powered by a high-speed serial computer expansion bus standard (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIe) interface of the main board, and is not directly powered by the power supply, and the power consumption of the display card is 75W at the highest, and the heat productivity is lower. In order to save the fan scheduling strategy, when the display card is only powered by the PCIe interface of the main board, the speed regulation is performed by adopting the onboard fan scheduling strategy. In general, the on-board fan scheduling policy is a constant fan rotation speed, and when the obtained power consumption of the display card power supply is less than or equal to 0, the rotation speed value is directly called for control.
Further, when the acquired power consumption of the display card is larger than 0, the display card is proved to be powered by the PCIe interface of the main board and is also powered directly through the power supply, and the display card is judged to be a high-power display card. At this time, the process of acquiring the system fan information and the environment information in the fan speed regulation method in the embodiment of the invention is continued.
In one embodiment, a process for calculating system fan flow demand includes: firstly, calculating actual power consumption P of a display card according to power consumption P 0 of the display card; and calculating the flow demand of the fan of the system according to the actual power consumption P of the display card and the environmental information.
Specifically, at this time, the display card is powered by the PCIe interface of the main board and is also powered directly by the power supply, so that the actual power consumption of the display card is the sum of the power consumption of the power supply of the display card and the power of the PCIe interface. Typically, PCIe interfaces may provide up to 75W of power for graphics cards.
Illustratively, the process of calculating the actual power consumption P of the graphics card can be expressed by the following formula:
P＝P0+75
illustratively, the process of calculating the system fan flow demand Q may be expressed by the following formula:
Wherein, T outlet is the temperature of the air outlet of the system, and T inlet is the temperature of the air inlet of the system. Typically, the usual test specification for T inlet is 10 ℃ above room temperature, typically 25 ℃, then T inlet = 35 ℃. According to the related standard requirements of the air outlet of the computer case, the temperature of T outlet =55 ℃.
Illustratively, when the graphics card power consumption is 225W, the system fan flow demand may be calculated as follows:
In one embodiment, the process of calculating the rotational speed of a system fan includes: and calculating the rotating speed of the system fan according to the corresponding relation between the rotating speed and the flow of the system fan and the flow demand of the system fan.
For example, when the system fan flow demand is 40CFM, the fan speed may be 3000RPM according to the system fan speed and flow correspondence.
In one embodiment, after calculating the system fan speed, further comprising: firstly, obtaining the model of a display card; then determining the noise loudness of the display card fan according to the display card model and the actual power consumption of the display card; and finally, correcting the rotating speed of the system fan within a preset range according to the noise loudness of the display card fan and the corresponding relation between the rotating speed of the system fan and the noise loudness.
The process of determining the noise loudness of the display card fan can be obtained through actual measurement, or can be obtained through calculation of the rotating speed of the display card fan according to the actual power consumption of the display card of different types of display cards, and the invention is not limited to the process.
The process of correcting the rotating speed of the system fan in a preset range comprises the following steps: firstly, determining the noise loudness of a system fan at any system fan rotating speed in a preset range according to the corresponding relation between the system fan rotating speed and the noise loudness; then calculating the difference between the loudness of the fan noise of the display card and the loudness of the fan noise of the system; and finally, correcting the system fan rotating speed corresponding to the minimum difference value to be the system fan rotating speed.
For example, taking the currently calculated fan rotation speed as 3000RPM and the current display card fan noise loudness as an example, according to the corresponding relationship between the system fan rotation speed and the noise loudness, the noise loudness of the system fan can be obtained to be 40db when the fan rotation speed is 3000 RPM. And determining the loudness of the noise of the system fan corresponding to the rotating speed of the system fan in the range according to the preset +/-200 RPM range. When the rotating speed of the fan is 2800RPM, the noise loudness is 37db; when the rotating speed of the fan is 2900RPM, the noise loudness is 39db; when the rotating speed of the fan is 3000RPM, the noise loudness is 40db; when the rotating speed of the fan is 3100RPM, the noise loudness is 43db; at 3200RPM, the noise loudness is 49db. The difference between the system fan noise loudness and the display card fan noise loudness under different rotating speeds can be obtained by respectively calculating: when the rotating speed of the fan is 2800RPM, the noise loudness difference is 8db; when the rotating speed of the fan is 2900RPM, the noise loudness difference is 6db; when the rotating speed of the fan is 3000RPM, the noise loudness difference is 5db; when the rotating speed of the fan is 3100RPM, the noise loudness difference is 3db; at 3200RPM, the noise loudness difference is 4db. By contrast, if the system fan speed at which the difference between the display card fan noise loudness and the system fan noise loudness is the minimum is 3100RPM, the 3100RPM is modified to be the system fan speed. In particular, the preset range can be enlarged or reduced according to the actual situation, which is not limited by the present invention; the number of calculations in the range may be increased or decreased according to the actual situation, which is not limited in the present invention.
When the power of the display card is higher than 75W, the load of the display card is higher, the noise loudness of the display card fan is higher than that of the system fan, the rotating speed of the system fan is increased after the speed regulation scheme is executed, and the display card works in a lower temperature environment along with the fact that the system discharges more hot air, so that the rotating speed of the display card fan is reduced. Further, when the rotation speed of the display card fan is reduced, the noise loudness of the system fan is higher than that of the display card fan, an approximate noise working point is found according to the noise loudness of the display card fan and the noise loudness of the system fan, noise is optimized, and other components in the system cannot be heated to a lower environment temperature due to the fact that the high-power display card is heated along with the improvement of the rotation speed of the system fan, so that double optimization of system noise and heat dissipation is achieved.
According to the fan speed regulating method provided by the embodiment of the invention, when the display card is in a low-power consumption state, the preset fan rotating speed can be used for controlling, and the waste of system resources is avoided. Through the calculation process of the flow demand of the system fan, the flow demand of the system fan can be directly calculated through the power consumption of the display card power supply, and the power consumption of the display card power supply can be realized only by the existing power supply feedback function without adding hardware. By correcting the rotating speed of the system fan, the noise loudness of the system fan and the noise loudness of the display card fan can be as close as possible on the premise of meeting the flow demand, so that the noise in the whole chassis system is the lowest, and double optimization of system noise and heat dissipation is realized.
The invention also discloses a fan speed regulating device, as shown in fig. 2, comprising:
