Per--
You can certainly view the amount of flex, if any, by standing alongside the
car and revving the engine. I recently removed a DW plastic fan when I
noticed that it had permanently flexed forward, undoubtedly decreasing its
efficiency. When I laid it on a flat surface the tips held the hub almost
3/4" off
the surface. I replaced it with a Nock Flex fan which was a significant
improvement.

The question is, should I worry about this flexibility? My fear is that it
might hit the radiator when the engine is revved.
