Case fans - are these worth it?

Hello - 3 days ago, I built my computer, and while it pretty much rapes all games I have, the pre-installed case fans are pretty crappy. My case, the Fractal Design Define XL, has great cooling options, and I would like to use that to the best ability. I am looking at getting 2 Corsair Air Quiet 140mm fans ( http://www.newegg.com/Product/Product.aspx?Item=N82E16835181028 ), 2 Corsair Air Quiet 120mm fans ( http://www.newegg.com/Product/Product.aspx?Item=N82E16835181021 ), and a Silverstone 180mm fan ( http://www.newegg.com/Product/Product.aspx?Item=N82E16835220039 ). Are these particular fans worth the price? All together, it is $80 worth of fans, a fee that I'm willing to pay if these are great fans. I want my graphics card, the EVGA gtx 680 FTW+ 4GB, to remain nice and cold, seeing as I'm unable to install a cooler onto it because of my CPU cooler (Phanteks PH-TC14PE) being as huge as it is. I was being conservative when making my list of fans, seeing as I could fit 3 more into my case along with these. Let me know what you think - my case theme is all black and red, limiting my case fan selection to my OCD (borderline official) and perfectionism. Thanks for any input you can provide!

 

Cheers,

EDIT - I have decided that 3x140mm and 1x180mm will move work better for my case. Using the same fans, it would cost the same to buy 3 of the Corsair Air AF140mm and 1 Silverston 180mm, would I get better airflow?

 

might be a little less, but shouldn't be a noticable diff in airflow, but the 3x140 will be quieter than if you got the 120mm's

I like the silverstone air penetrator fans (serious air flow directing in those fans) and have heard good things about the AF series fans. Just make sure you keep a positive pressure inside the case to keep it both clean and at its coolest.

Edit: Also if your case hase restrictive items like that black rewashable fan filter that fractal uses in some of their cases then maybe a more pressure oriented fan on the intake or exhaust with the filter material will help you with air flow .

What about the fractal fns is bothering you, because if its noise theyre actually rated better than the corsairs.

The old fractal design xl fans had very low RPM and don't push much air at all IIRC.  People were complaining about that with the Define R1/R2 as well.  So they included higher RPM fans in the Define R3 and beyond.
