watch out for restrictions in front of and behind the fans (like the
engine). CFM ratings have to have back pressure factored in, and CFM vs
backpressure is a function of fan blade/housing design. Hopefully the
catalogue guys figure in some nominal backpressure to make their numbers
"real". Doesnt seem like 2950cfm is enough does it...
