Thanks for that, D.
It seems so odd that the fan revs right up the instant i throw the car into a right turn: Revs up instantly with the turn-in, and continues to rev high as long as the centriugal force / turn is happening. Straighten out the wheel and the fan speed drops right off. With the road noise at speed, its difficult to hear, but there is no grinding or squeeling; just a very low motor boat sound.
