That post is for adding a fan to the 'Official' Pi Case. The post I linked added to that by having a .py control to turn the fan On/Off based on the temp (and used a transistor and Tony  SBTouch ♪ SBRadio ♬ ------------------------------------------------------------------------ Tony T's Profile: http://forums.slimdevices.com/member.php?userid=34544 View this thread: http://forums.slimdevices.com/showthread.php?t=110727 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
