Consult the fan design and see how its rating varies with pressure on one

The restriction on the inlet side that David mentions would include the
effect of any air filter. This might appear to be obvious, but it does mean
that the filter has has to be cleaned when necessary to maintain proper air
flow, a task often forgotten. I believe that air cooling systems should
include air filters whenever possible.
