Overheating 360 new engine

I get a kick outta how many folks forget about all the parasitic power loss thru friction, belts, bearings, brushes, magnetism, drag, etc, etc. that a water pump mounted fan doesn't have.
Clutch fans don't spin over 4k ish, and sorta freewheel when hot.
Each has it's advantages, mounting being a deciding factor .
Electric fans do take power, it's not free !
My racecars have significant rpm loss when the fans kick on !
