[0005] However, the temperature sensing signal ST used by the fan control system 100 to control the rotation speed of the fan 140 does not accurately reflect the temperature inside the hard disk drive, because the temperature sensor 110 is not installed inside the hard drive drive, so it may lead to improper operating conditions
For example, the fan 140 may reduce its speed due to a low temperature sensing signal ST, but the temperature inside the hard disk drive may be too high, but the high temperature inside the hard drive drive has not been transmitted to the temperature sensor 110 to affect the temperature sensing signal ST, so that will reduce the life of the hard drive
Therefore, although the fan control system 100 has the function of saving energy, it may reduce the service life of the hard disk drive

The invention discloses a fan control system and a related method thereof for controlling the fan operation of an external hard-disk cartridge by utilizing a data signal stored in a hard-disk drive. The fan control system comprises a hard-disk signal capture and process circuit, a drive control module and a fan. The fan control method comprises the following steps: utilizing a reading request instruction to capture a data signal from the hard-disk drive, decoding the data signal so as to generate a temperature-sensing signal, adjusting a control signal according to the temperature-sensing signal, and adjusting the rotation speed of the fan operation according to the control signal.
Description
Technical field [0001] The present invention relates to a fan control system and method for an external hard disk box, in particular to a fan control system and related methods that use data signals stored in the hard disk drive to control the operation of the fan of the external hard disk box. Background technique [0002] At present, external hard disk enclosures have become very popular. Almost every computer system user has at least one external hard disk enclosure to provide the computer system to be coupled to the external hard drive. Therefore, users can use different computer systems. Access the data of an external hard drive. Generally, an external hard disk enclosure is equipped with a cooling fan to reduce the temperature of the hard disk drive, and most of the cooling fan mechanisms of the hard disk enclosures on the market only provide a switch function. [0003] However, in this era where energy conservation is emphasized, for external hard disk enclosures that are u...
