You'll get more flow and higher pressure from a centrifugal blower. They are also quieter. If you want some serious flow, you might stop at a junk yard and find a blower used for AC/Heater. They are generally quite large, and capable of some serious air flow.
Noise comparison for bilge vs centrifugal motor cooling
I'm wanting to add some cooling to my motor (ES-31B @ 120v) before Houston summer arrives.
As I understand it, either a bilge or centrifugal (squirrel cage) blower is required (similar to those pictured below).
Is there a significant difference noise-wise? bilge's seem much cheaper ($20-30 vs $60+) but I'd like to keep noise down also.
