I have heard good things about Noctuas but I haven't used them myself. I got a 120 Silenx. They are pretty decent with a good air flow and relatively quite but not as quite as their specs say they are 14 dba, I think not. I also got a Cooler master 120 fan which is also pretty quite. I don't know if I was unlucky but 2 of them have gotten a bad led within 1 week of usage. It pushes less air than my silenx. My case is also a TT armor, how come you got 3 x 120 mm fans ? you must have added one ?
Anyways, I haven't replace my 92 mm yet, I'll probably go for the SilenX even though they are pretty expensive.
I have also heard good thing about Yate loon fan.
