    Help! MBPro fan constantly at max speed - how to find problem?

    My daughters MBP 2009 2,53 Mhz Duo received a new main board (It is the one with only 1 fan) . So far, everything is ok. BUT: the fan is constantly turning at max speed from the start on, instantly when I push the "ON" button... I installed macsfancontrol and it shows LOW temperatures...
