skott,
generally, you make some very worthwhile posts, but this last one intriged me to prove you wrong.

lets say you have a fan on youre car that pulls air through your radiator at 1800 cfm, which is pretty reasonable i believe. 1800 cfm is one thousand eight hundred cubic feet per minute. in any given minute, there are 1,800 "cubes" of air coming through that fan at one foot by one foot by one foot lengths. if you have 2 fans, the total amount brought through the core of the radiator is doubled to 3600 cfm. that translates to roughly 40.91 cubic miles of air per hour. so, given that the fans are running at maximum efficiency, after about 41mph, your fans are no longer helping, but hurting the flow of air.
my guess as to why your head gasket blew was because your friend was beating the shit out of your car, or you need to put some ducting between your intercooler and radiator. the later of the two has proven to be the most effective way to cool your engine down at speed short of pooring ice water into it.
