If the external control device 4 compares the data (e.g., wind speed data) in the gas sensing signals of at least one fan 2 (e.g., 2 fans 2) with the default data, the external control device 4 controls and adjusts the rotating speeds of the 2 fans 2 different from the default data based on the default data (e.g., default wind speed data) to further change the wind speed of the gas blown by the fans 2, until the data in the gas sensing signals of all the fans 2 (i.e., the fans 2) are the same as the default data, at this time, the wind outlet sides 222 of the fans 2 flow out uniform airflow, and the overall flow field of the wind outlet sides 222 relative to the fans 2 is uniform, thereby avoiding the generation of vortex and further effectively achieving the effect of reducing noise.

In an alternative embodiment, the microcontroller 31 of the gas sensing unit 3 may be omitted, and the processing unit 21 of the respective fan 2 may be used instead of the calculation process.
And the data in the gas sensing signal contains corrected wind pressure data, and the default data contains the default wind pressure data. Wherein the correction data is a correction coefficient for correcting the temperature value corresponding to the temperature sensing signal; and the manufacturer executes a test procedure before the factory leaves the factory to obtain the calibration coefficients of each manufactured gas sensing unit 3, and the calibration data is stored in a memory (such as a Random Access Memory (RAM), a Read Only Memory (ROM), an Electrically Erasable Programmable Read Only Memory (EEPROM), a flash memory or other memories; not shown) of each gas sensing unit 3.
