Yes, I read it. Logically and intuitively, a 3 degree difference of IATs at idle sounds right ..... there is so little air flow over the IC at idle, the fluid (in the HE and IC) could be ice cold and it won’t lower IATs much.
Check me on this .... the 3 degree difference was IATs, not actual fluid temp, right? I’m just saying that I would theorize that fluid temps in the entire cooling system at idle will be much cooler with the fans .... but you won’t realize the benefits until after you gas it up and get air flowing through the intake. It’s then that you will see the IATs drop faster because the fans have kept the fluid cooler while idling.
