Quiet/Effective PWM fans for dual 120mm radiator?

post #1 of 8
Thread Starter 
I bought a Seidon 240M from Cooler Master (http://www.newegg.com/Product/Product.aspx?Item=N82E16835103181), and I'd like to replace the stock Cooler Master fans as they have a somewhat irritating bearing noise.

The radiator has ~26 fins per inch (or ~13 fins per inch if you count every other), and is mounted in front of my BitFenix Prodigy. The fans bring in cool air, and push it through the radiator where the warm air exhausts out the rear and top of the case.

What PWM fans are quiet and effective? Ideally I would like fans that are almost inaudible at lower voltages, and not too terribly loud when under load.

these are real nice
I have about...18?






PWM response is good, pressure is good.
I really wanted orange for a build, I could not find Aerocool Shark Evil Orange
(I did eventually, cannot recommend-noisy)
Also available in all black, also available in 140mm
edit: eloops push a lot of air but have a resonant frequency I could not stand.
(even on controller)

just make sure you don't mount the cougar vortex as horizontal exhaust

if you mount ur cougar vortex fans at the top of your case like this:

|---EXHAUST---|

you will hear a buzzing sound.

source: i have 4x vortex attached to my h100 and the fans make a horrible buzzing sound if you mount them as exhausts.

apparently this is due to the ball bearing design they use.

Yup, I know that from personal experience. My previous machine was an NZXT Vulcan, and I bought the Enermax TB Silence fans specifically because they could be used horizontally. No bearings/lubricant to worry about, they operate solely on magnets. Wasn't as powerful as other fans though :\

They look very similar in design to the Enermax TB Silence PWM fans, but are they similar in performance?

thing to remember with this chart, under the cfm range columns is the decibel min and max and under the dba range is the min max cfm range. its an old chart but still very relevant.
the helix pwm fans would be a very good choice.
