What's to say.. If it works it works.
On my F5 coupe I just upgraded the fan to a Lincoln MK VIII fan/shroud setup. Two speed fan and controls. Drove the car last week when temps were in the mid 90's here with the A/C on and it never went over 195 on the water.
Oil was up to 230 or so when running hard but that should be fine with todays oils.
