Re-check for thin cable(s) missing from a connector on one of the fans.
the system has a cpu fan only there is no other fan on the unit. also the cpu fan is spinning i was able to look in the bios, i found the cpu temp was being monitored but there was no section for system fan nor to alter cpu fan modes it was all greyed out. do you think it could be a problem with the mother board?
