Silent Fans

Hey Guys,

I'm looking for silent fans. Currently im running a few of the Coolermaster SickleFlow 120's (http://www.coolermaster.com/product.php?product_id=4375) 2000RPM, 70CFM & 19dB. But one or two are starting to show age and dust buildup (Major DIY/Brick dust got to my machine :( ) and have started to grind/not spin at full RPM.

Wondering if you guys know of anything better? I do remember seeing something not long after buying these but for the life of me cannot remember the name.

EDIT: This is what i've got so far:

I just recently bought 2x Corsair AF 140mm fans for my case, based on their fantastic reviews. However, they are not very quiet. My case, the Fractal Design Define XL USB 3.0, is extremely silent, but those fans are noticably noisy. I am getting some Scythe Gentle Typhoon fans now - much better :)

These are probably the best fans for both silence and great airflow:

Cheers guys. I've started creating a list. I'll add it to the original post.

Just an option ! 

If you are really worried about noise, why not reduce noise by adding some noise dampning material on your case (If there is room for it!)

I'm not too fussed on noise, but i just dont really want loud ones.

Also, im using an Antec P183 which does already come with noise dampening built in. More can't hurt though ;)

 

I wont suggest adding multiple sheets, as it might affect air flow in some areas. (Fan covered area)

In this case, better go for silent fan or water cooling.
