depends on the fan.. if you have an air-fan-clutch you get Much more fan noise because your fan is either fully engaged or fully disengaged.. so when it comes on its typically a big roar similar to that you hear when semi truck fan comes on.. most of the air fans ive seen are many-blade plastic fan wheels which move alot of air but also are noisy..
if you have an old school thermal fan clutch(its completely mechanical) then your fan gradually speeds up and slows down as the air temperature from your radiator increases or decreases. so you may almost never be running your fan at full speed unless you are under high temperature / heavy load...
thermal fan clutches fail quite a bit more than air fan clutches do so they went to air.. also the fans on the thermal clutch fans ive seen are mainly smaller number of blades and metal so they are typically a lower pitched sound when they operate.. though can still roar pretty good..
P.S EDIT: I should add that mechanical thermal fan clutches are typically MUCH cheaper to replace than air actuated fan clutches.. AND they CAN be adjusted...
