[Amps] Fan/Filter

[Robert Dorchuck]

The Alpha website shows it as 71 CFM.  Same fan they offer for the 8410 
but I used a quieter 61 CFM EBM Papst model 4800ZW fan available from 
Allied (and other sources).

I have an Alpha 91b that I wish to add a fan to the opening on the back. 
Is it real critical as to the the size of it, speaking of cfm's, or will 
anything help? I have several fans that will fit the hole size.
