can anyone chime in if this is normal?
Two likely unrelated things. Normal for the power steering pump to make more noise on full lock, but as others suggested, check to make sure the fluid level is OK. If it's low, it can make this sound more pronounced.

As far as the fan staying on after turning the car off, this is normal. Depends on the environment/conditions.
