Efficiency of aluminum fan vs. plastic
Jeg's and Summit has a Perma Cool electric radiator fan with aluminum blades that is rated 2950 CFM on a 14" blade, which is substantially higher than the published numbers for competitors plastic fans. For Jeg's, the flow numbers are only available in the printed catalog, I couldn't find them online.
Is aluminum the way to go for a hot engine, or is this just marketing hype? Pros and cons of aluminum versus plastic?
