Produce CAF for fear of described printed circuit board (PCB) 101, described computing machine also comprises:
Above-mentioned humidity module 103 can be a humidity sensor, is installed on the described printed circuit board (PCB) 101, perhaps, also can be installed on around the described printed circuit board (PCB) 101, or, be installed on described computer case inner other positions, for example the most hygroscopic position of enclosure interior.
The humidity value that described humidity module 103 gets access to can be absolute humidity value (quality of the water vapor that contains in the air of certain volume), also can be rh value (ratio between absolute humidity and the high humility), perhaps humidity value physical quantitys such as (being melted in the ratio between the quality of the quality of airborne water and soft air) relatively.For convenience of description, the humidity of indication all is meant relative humidity in following examples.
When described humidity module 103 gets access to the humidity of working environment of described printed circuit board (PCB) 101, send described humidity to described comparison module 104, described comparison module 104 compares a described humidity and a predetermined threshold value.Generally, surpass at 85% o'clock in humidity, described printed circuit board (PCB) 101 is easy to generate CAF, therefore, in the embodiment of the invention, can suppose that described predetermined threshold value is 85%.In addition, the humidity of supposing the working environment of the described printed circuit board (PCB) 101 that described humidity module 103 gets access to is 88%, at this moment, the comparative result that described comparison module 104 obtains is that the humidity (88%) of the working environment of described printed circuit board (PCB) 101 is greater than predetermined threshold value (85%), described comparison module 104 is exported first control signal, and described first control signal is transferred to described fan control module 105.
