ABSTRACT:
The present invention disclosed a method and device for monitoring computer case and power supply unit. Expanding monitor chip acts as slave device of SMBus to form the monitor device on the SMBus of computer integrated master device to measure the fan speed, temperature and working voltage of the computer case and power supply unit. Once the temperature signal received by temperature sensor and input to the monitor chip, it will processed by the monitor chip then outputs a control signal to control the fan speed via an amplifying driver circuit. The SMBus is connected with the connection head of the SMBus of PCI Express board, PCI board, PCI-X board and/or computer mainboard. With the method and device in the present invention, a smart computer case and power supply unit may be formed to reduce noise and power consumption. By monitoring working status via a program by the communication between SMBus and computer, it helps with better management of computer case and power supply unit device.
