Highest CFM fan - Page 8

post #71 of 98
why not just get a leaf blower and mod it with moldings to blow into a 120mm hole?

Im pretty sure that would pump out some extreme CFMs

heres some more realistic solutions they push 1000CFM

I think they are around 150mm but I know they have have high cfm

This made me really Only 222lbs..rofl..

I didn't read all the pages...why you looking for such an insane turbine?

There is a company that makes nice 120mm fans with high cfm called Grainger if you need to purchase you can go through myself but its not a fast process takes them about 2-4 weeks to get me your product then ill have to ship it to you sadly they dont drop ship..................with the cfm you are wanting you will need to exhaust all that air as fast as you intake it or your case will literally explode from the airpressure and be sure to use good filters for your intake fan and use a large server case as well.

Nice Fans

Grainger is an industrial supply company; my uncle works for them.

Those fans are actually made by Dayton; a very well known fan motor manufacturer. Do keep in mind that most of the fans you see listed there run on 120 volts AC (some go up to 230 volts AC and others are 24 volts DC)

You really don't realize how much air flow that is. I'm in engineering for a compnay that builds radio station transmitters. For a transmitter that's the size of a large fridge, with probably 10 fans or so in it, with 5 or 6 of them being larger 200mm 52.0V fans, it moves just under 500 CFM. So how are you ever going to get air flow like that out of one fan?!?! Go get a jet engine intake or something. lol.

Seriously, all that room temperature air going thru your case won't make much of a difference unless you find a way to chill the air. Getting air in and out of a case quickly can only do so much.

4120 acctually
also remember that once you start sticking this much air through a hole that's as small as 120mm you start getting into something really really nasty my professors like to call 'compressible flow' it does some nasty things to the fluid continuum and makes it really hard to analyze exactly how many cfm's the fan outputs, also it need to go superduper fast like.

Funnel it, and you'll have storm.
You will need a HUGE bell mouth inlet to acheive these speeds and an unlimited supply of air. (your bedroom is NOT big enough. nor is your house.) without an excessive bellmouth the turbulance created at the inlet will destroy you're airflow. If you don't believe me, ask this dead guy named venturi. he'll tell you all about it.
