Upgrading fans

so i built my first ever pc earlier this year and got a  CORSAIR Hydro Series H110 for the cpu. http://www.newegg.com/Product/Product.aspx?Item=N82E16835181035

 

 

the only problem i have with it is that the stock fans are making my ears bleed!!! i remember there being a tek syndicate youtube video of some led fans that were super quiet and pretty cheap. i thought i had it under my favorites but cant find it any more.

does any one know what im talking about?

 

i find lights kind of distracting, so id rather not have leds, but can any one recommend some quiet fans that will fit on my radiator and be whisper quiet. also not looking to spend more then $50

Noctua?? im not that much of a fan expert but Noctua are supposed to be super quiet, but I'm not sure they would fit on your radiator...
