The RR website says the following about the 4 zone climate control option:

“Enhanced air-conditioning delivers stronger cooling, better airflow, less noise, and more comfort than ever. The center top vents boost front ventilation and significantly quieten high fan speeds,”

I’ve noticed during 2 test drives (on models without the 4 zone option) that the fan noise of the AC is relatively loud. Can anyone comment on how much the 4 zone option reduces the fan noise, if at all.

Thanks
