EBM/Pabst blowers are significantly quieter than Dayton.  They make many 
sizes.  Look them up on Google.  I have a G2E085-AA05 EBM blower that will 
cool a pair of 3CX800's.  The blower generates 56 CFM @ 0 back pressure. 
The complete specs for this fan is on the EBM website.  I used the twin to 
this blower to cool a pair of 8874's in a Dentron MLA 2500 conversion and it 
was overkill.   $50 plus $10 Priority shipping.

Also have a EBM/Pabst G2E120-AR54 blower that generates 152CFM@ 0 back 
pressure.  I am using the twin to this blower to cool a pair of 4CX1500B's. 
It's a little louder than the 085 but blows 3x the air.  $80 plus $10 
shipping.  BTW, both of these blowers are 115vac and have the start caps.

Thanks for reading,
Bob W6TR
