FAN CONTROLLING CIRCUIT FOR SERVER COMPUTER |
摘要 |
A circuit for controlling fans of a server computer includes a temperature sensing module configured to sense a temperature inside the server computer and a complex programmable logic device (CPLD) connected to the temperature sensing module. The CPLD includes a pulse width modulation (PWM) module connected to the fans. The PWM module is configured to output a plurality of PWM signals having different duty cycle values to control a rotating speed of each of the fans. The CPLD is configured to determine whether the temperature exceeds a tolerable value.
