Isn't the hood blocking? I have 2 huge louvers in the hood to help air escape, would be counter-intuitive to me to block them off. Though I agree a lot of air does come out between the hood and windscreen.

The fact I don't use a shroud might also be a reason for hot idle.
He's talking about the space over the radiator, between it and the hood a very small space a little over an inch in the middle that tapers down toward the sides. Check out i think it's AZPete's thread where he posted this mod.
The shroud does make the fans much more efficient in directing the air the fans pull thru the radiator.
