SPAL fans certainly have my vote as being the best. I have used a bunch of other brands and when I got my first SPAL and turned it on while holding it in my hands it almost took off on it's own. It moved a lot more air than any fan I have ever had, and the life expectancy is much better............I don't think I have ever had one fail, even after years of use.

Years ago I had a conversation with the President of PRC radiators at Turkey Run and he said they regularly test every fan on the market and SPAL consistently out flowed them all.
