I'm not 100% sure, but at higher speeds, the fans normally won't kick in because the heat sensor isn't detecting high temperatures.

But, if the grill blocking was too effective, and the temperature got too high,
the fan would be turned on. (Which is what happens when I'm stuck in slow traffic).

I think the trick is, to get the engine good and warmed up, but not extra hot.


So, if the venturi effect of air passing under the skid-plate area creates
a little low pressure around the engine, that might suck enough air through the radiator.?.

Maybe I will tape up the nose before I spent $89.95 for the Car Bra.
