I have no idea if this has been covered in some long lost thread or even brought it up myself and just don't remember, but I'm being lazy today and not searching (and actually have no idea why it popped into my head right now)
Anyway, I was walking around in a parking lot a while back and noticed on a Saab or BMW or something that the radiator fan was mounted on the front side of the rad vs facing the engine. This got me thinking about all the time I spent in computer modding and when doing chip cooling it's more efficient to push air through the heat sinks than pull it out.
Would this concept apply to automotive cooling as well? Would it be more efficient (fan stays on for a shorter amount of time) to have the fan blowing air through the rad instead of pulling air through it?
