I browsed the forum for info on fan control without luck.
If I understood right (please correct me if I am wrong) fan control works by switching on and off power supplied to a 9V fan flowing/feeded trough the board. Or should the 9V merely act to activate an external switch and the fan must have an autonomous power source?
Which specifications should this fan meet? I guess in the first scenario fan power will be limited by the capacity of the 78L09 regulator, which should be 100ma?
Couldn't we use a 12v fan instead, as these are more readily available?
Also, under which circumstances/parameters does the fan switch on? I guess these are not configurable?
Forgive me if I am placing silly questions
Thanks
