Hehe, back a few years ago I got into something called overclocking. You do this to a computer to make it run faster. (very undetailed explanation, I'm saving you all ) Anyway, back in the "day" you either used water or high powered PC fans to cool the processor. I went the air route, In my PC case were (4) delta "Black Label" 60mm fans that spit out about 55-60db of high pitched motor and air noise each. You'd think the computer case was going to hover. And you could hear it when you walk in the front door of the house. Boy I mis those days... not.

Anyway, that fan you got sounds like a winner in my book, if this home made 120mm inline fan thing I'm making doesn't do well, I'm getting it.

Thanks!
