Please help me select a fan

This is for my Thermalright Ultra 120 Extreme:

S-Flex, Yate Loon LED , Normal Yate Loon ?

I'm not worried about lifespan
I know that S-flex fans last longer than Yate Loons, but that doesn't really matter to me, since the price of 1 s-flex is 3x the price of yate loon. I might as well just buy new ones after they die.

Performance issues?
Anyways, is there a huge performance gap between yateloon and s-flex fans? Normal Yate Loon fans are 28dB compared to S-flex's 20.1dB. However, this is for my Thermalright Ultra 120 extreme, and will be inside the case. Will it still be too loud?

LED or not?
If I decide to go with the Yate Loon fans, should I buy LED or not? My case doesn't have any windows, but I guess it looks good for pr0nz. Do LED fans perform just as well as normal fans?

anyways, please give me some suggestions/better DEALS before I make this purchase tomorrow. Thanks!

LED fans are just fine.

I'd go with a yate loon over any Sflex fan.

Clear fans tend to be a bit louder than solid black fans ... something about the quality of the plastic.

Read about it somewhere on SilentPCReview, and I've also noticed a difference in noise output between Antec's TriCool fans (black vs blue LED, 120mm).
