I don't think it makes much sense to use cpu-fans in 1U chassis - 
not only are cpu-fans *in*general* less reliable, but you'd 
constantly be facing this sort of problem.  not to mention
the fact that the overall airflow would be near-pessimal.

far better is the kind of 1U chassis that has 1 or two fairly
large, reliable centrifugal blowers forcing air past passive 
heatsinks on the CPUs.  there are multiple vendors that sell
this kind of design.
