Thermaltake Orange 120mm are great. Silent and great flow.
AeroCool make decent fans.
Papst is a great brand from germany, make both silent and good airflow.
ADDA are good.
Coolink is a new brand, try them, cheap but good quality. Look good too, have blue fanblades, and no they are not LED.
There are many good fans, but these five are my fav.
Ps. I use Zalman ZM-MFC1 to controll all my fans. It has 6 controls w/ both 5v and 12v connections. Its great. If you want to see movies or just surf you turn them down to silent, and when gaming or other stressful things you turn up to max.

It looks great too, but it does have led lighting so if you dont like the bling bling, stay away..
