John,

I'll tell you what I think it is and if I'm wrong,  I'll quickly be shot 
down
:o).

Basically, there is no cooling air  until the thermostats open the doors. 
The
fan just spins without moving any  air until the doors open. Of course this
assumes that all shrouds are in  place and operating properly.

You've got that right; the air enters between the big fan and the turkey  
roaster, gets spread out by centrifugal force; the turkey roaster causes the 
air  to go downward, massaging the cooling fins, then to the lower plenum, 
where the  doors control the air flow, stopping the flow of air until the 
engine warms  up.
BTW, removing the lower plenum and doors induces better cooling but slows  
the warmup considerably. 
 
PLUG: look at fastvairs photos under the name of "cottysay" for improved  
fan designs.
