on the series 60, at high idol, when unplugging the solenoid at the hydraulic block in the back near the radiator the fan will roar.
when it is plugged in the fan may or may not run depending on the temperature of the engine. sometimes the fan will not be running, sometimes very slowly and if really warm (below 204 on the series 60) if will run but not roaring.
on my series 60 when the engine temp hits 204, the high speed fan mode kicks in and it will cool the engine down very quickly.
