Thanks for the replies!
Makes it a lot more clear to me.
What about noise levels? are they also "as quiet" as a normal fan?
And if they are, why would anyone still use the normal fan's?
They are a lot more expensive than the blower I've seen from the link.
http://www.allelectronics.com/cgi-b...&type=store but the noise level 66 dba.............. that is a lot! but I guess that's at 12v.
I have no problem kicking out my PAPST fan's and replacing them with one blower, it the performance would go up, and the noise level would go down....
What's the best blower (performance, noise level wise) out there?
