Actually, it's been shown that the CAT/ECT are closely linked. It makes sense considering the fact that the heat extracted from the FMIC basically goes straight into the radiator.
No, the flaps are designed to improve cooling while stopped with no frontal air flow. Without those flaps the negative pressure created by the fan cannot be distributed to the area that is not directly in front of the fan. Removing them does not improve cooling efficiency at speed and reduces cooling efficiency while stopped.
