Great minds think alike xbUser! Although i thought about that and i think it would make the system heat up very quickly but then need the fan to cool it. From reading stuff here and at cleanMPG i believe it is not good for FE having the fan coming on all the time. I think it's better to have a constant supply of air to stabilise temps. My temperature graph might end up looking like a sawtooth instead of a gradual rise and then a plateau, with maybe the odd spike when i get stuck behind a particularly slow moving truck or what have you.

Mind you, a variation of what you suggested would be good. Say you have a grille block that has a small opening. This is fine until going up a hill or are stuck behind a truck. Then the airflow is worse. So you could have the opening get bigger when the fan comes on, reducing the time the fan has to be on. Any thoughts?
