I did explain my observations of the ratio between fan speed/engine rpm with my single hydraulic pump system and hydraulic manifold components.
Fan Low Speed is approximately one halve the engine RPM - Fan 12v DC Solenoid Energized).
Fan High Speed is approximately the same as engine RPM - Fan 12v DC Solenoid Not Energized (in this state, the spool valve shifts and all fluid flow goes to fan motor. The logic valve senses steering gearbox requirements and diverts flow accordingly).
I will have additional discussions about the fan and per his comments, the inability to exhaust heat from the engine compartment especially with the compound turbo charger setup.
