the fan is always on but the viscuous fan clutch locks at an external temperature of about 107C which equates to 120C+ coolant temps. in that respect the fan clutch is next to useless. when it's not locked though, the fan still turns and provides a considerable amount of cooling. i think you can't get rid of the fan altogether, your engine would definitely overheat. there was a thread recently on converting to electric cooling fans you may want to check that out...
