Be quiet fans for rad?

How do the be quiet fans stack up against the Noctoua fans for radiator performance. I have heard some good things about them, but would like to hear if someone on here has a good experience with them. Also I would think that the silent wings http://www.newegg.com/Product/Product.aspx?Item=9SIA68V21E0611 would be better for static pressure due to their thicker fan blades, but how would the pure wings http://www.newegg.com/Product/Product.aspx?Item=9SIA68V21E0613 fans do? I am going to be putting them on a h105 because the fans that came with it have horrible whine.

Without the low noise adapter, the NF-F12 destroys both of those fans. With the adapter the NF-F12 still has the advantage when it comes to static pressure, but has slightly less airflow.

The biggest difference between the Pure Wings and the Silent Wings is the the bearing used (Rifle bearing versus Fluid Dynamic Bearing) and the accompanying kit. The Pure Wings comes with just the basics, the Silent Wings comes with some additional mounting solutions which help with eliminating vibrations.

The performance difference between these and the Noctua are measurable, but it is not going to make or break your build. The Noctua will perform a couple degrees better, but will be slightly louder as well. If you can hear either over the other ambient noise, the difference you will tell will be that the Noctua make more of a motor whir, while the Be Quiet! have more of an air-moving whoosh sound. (Very technical terms, I know.)

I usually recommend Arctic Cooling F12 fans, or Enermax fans. Both perform quite similarly, in terms of thermal performance and level of quietness.

NF f12's dont waste your time with beshit fans

Wat.

Should have clarified this in the post, but I don't really want to spend more than $20 on a fan. I just want something that is fairly quiet and doesn't have the terrible motor sound that the corsair fans in my pc have.

You could try capping their RPM at ~1500. They should be fairly quiet there, and perform similarly to all the others mentioned.

OK well then are there any good options 15$ or less for a radiator, if not I will use something that is above.
