silent ventilation(sort of aero)
 

i've a small :D ventilator from an dead mobile airco from school recovered.
here are some pics


when i put it on i tough omg wtf is this.
is has a little bit of air coming out of it.
a little bit later when i put my hand for the outlet, the fan increase the spead automatic and quick he has a HUGE airflow::grin:

these sort of fans have a bad noise/performance ratio when it comes down to CPU cooling, don't know if this also applies for aircooling, if you put this at the side of your case I think you can do away with all the fans in your case,

now only to override the automatic speed regulator so you can set the required rotation speed & minimise noise:)

mod it and cut everything open at the back of a case so there's a constant airflow :mad:

is it noisy ? and can you silent it by lower the voltage or will it malfuntionate then ?

maybe but at low speed you almost can ignore the sound. i dont think i am going to use it in my pc. maybe in my project phase-change under my pc to cool my rad
performance:it hase a very good warp of air ,thats my opinion
its just a MAD vent

oh yes, no doubt, but put a like-wise sized radial fan next to it, and at the same CFM output it will be quieter, and at its maximum speed it will still be more silent and produce more CFM :)

don't take my world for it, just make your ears work: http://www.madshrimps.be/files/article-jmke-68.wmv

nice
but i can asure you the fan isn't that noisy

same way a 200mm radial fan won't be as noisy as the 80mm version

i am not intend to cool my cpy with it
because later the day i am going to put my phase-change on it(try)

uhm.. I figured out that part, that's why I mentioned it, good luck finding a heatsink that will that thing even if you wanted to ;)

My father works in a building, they got gigantic radial blowers (1 meter wide I think :D ), and they are quiet, yet powerful (I once cought a cold because of that thing :(
