this isn't necessarily computer related, but since i'm using computer parts, might as well ask here
i have a car with a very small two seater cabin, and while the AC works, it tends to cause the engine to overheat on very hot days. I intend on building a separate cooling system like the icebox evaporative coolers on the interwebs, except i want to pump ice cold water from a ice box reservoir into a 360mm radiator, and use fans to draw in the warm air to cool it down. I intend to use 3x 120mm fans.
my main concern is that at 12v, the fan won't spin fast enough to provide adequate air flow through the radiator to cool the car. Cooler Master advertises their fan to move about 70cfm of air at max RPM, and with 3 of them moving 210cfm of air, that should be more than enough to cool the car Apparently, max rpm is at 6000RPM. At what voltage do i need to run it at to achieve that speed? noise is of absolutely no concern. I was thinking about running 2x 12v lead acid batteries in series to push 24v.
Also, since i don't intend to run these fans for hours and hours at at time (i pretty much have my computer running 24/7), lifespan is really of no great concern to me. these fans are cheap, and they are easily replaced, but i would like to get a very rough estimate on how long they would last with 24v driving them.
Thanks.
