Avoid those Areocool fans for sure. Many people say how bad they are...
You could try something like these maybe:
Bluegears b-flexi 120mm 4-in-1 LED Case Fan - Sleeved Products Model: b-flexi120 [b-flexi120] : Performance-PCs.com, ... sleeve it and they will come
And these CM ones:
Hyper 212 - Cooler Master
Though I have no idea if you can get the fan by itself, but it fits what you want.
The best choice would be to take a good black fan and then mod in some LEDs.
