Embodiment 1

[0044] See attached figure 1 , Is a schematic flow chart of a method for automatically adjusting the speed of a computer fan provided by the first embodiment of the present invention. The method is suitable for a scenario where a computer fan is adjusted. The method is implemented by a computer fan speed automatic control system. The control system includes an EC chip and an Intel chip connected to the EC chip through a PECI bus. The method specifically includes the following steps:

[0045] S101. The EC chip reads the energy consumption value currently estimated by the Intel chip.

[0046] It should be noted that the PECI standard released by Intel (Intel) allows smart chips (for example, EC chips) to control the temperature of the system.

[0047] S102. The EC chip compares the read current estimated energy consumption value with the previous energy consumption value.

[0048] Exemplarily, the comparison may be performed every 1 second.

[0049] S103: If the currently estimated ener...

Abstract

The invention discloses an automatic rotating speed regulating method and system of a computer cooling fan. The method comprises the following steps: reading current estimated energy consumption value of an Intel chip through an EC chip; comparing the read current estimated energy consumption value with the previous energy consumption value through the EC chip; if the current estimated energy consumption value is more than the previous energy consumption value, controlling the computer cooling fan to increase the rotating speed through the EC chip; and if the current estimated energy consumption value is less than the previous energy consumption value, controlling the computer cooling fan to reduce the rotating speed through the EC chip. With the adoption of the method and the system, the fan can be controlled to change the rotating speed in advance so as to pre-cool the system, thus the problem of delayed heat dissipating is avoided, and unnecessary fan energy consumption is reduced; the whole adjusting process is accurate and quick; the fan runs smoothly; and the produced noise is decreased.

Description

Technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a method and system for automatically adjusting the speed of a computer fan. Background technique [0002] With the rapid development of computer technology, computers have become an indispensable tool in people's daily life and work. Due to the continuous improvement of computer performance, the processing performed by it has become complicated, and the calculation speed of the central processing unit has also increased relatively. The central processing unit will generate heat under high-speed operation, which will affect the system. In the lighter case, the system may crash, or even the system may be unrecoverably damaged. Therefore, more and more attention is paid to the research of system heat dissipation. [0003] Air-cooled heat dissipation is the most common heat dissipation method in the industry. Fans and heat sinks form an air-cooled heat dissipati...
