standard A12 clutch fan

Do you mean the B310 clutch fan used with Air Conditioning? The standard fan is a fixed fan, and has no clutch


...to a 10" thermo

The B310 clutch fan is thermo controlled. It spins more freely when cold and less free when hot. It is 350 mm diameter - steel, 7 blades.

Nissan thought it is was important enough to use instead of the standard fan. My guess would be as much as 5 HP at 6000 RPM for this fan if not using a clutch.

The standard 310 mm diameter plastic fan takes what? 1 or 2 hp?

For the best savings, use an electric fan like that used on N10 or B310 models. That can save 100% of the fan power when the fan is switched off. It only runs when the engine needs it. Electric fan: 320 mm diameter, steel 5-blade (some 1980-1982 B310s)
