I have 4x 120mm Antec Tri-Cool blue LED fans in my Lian Li and I love them. Nice and bright and you have three fan speed settings. But they are loud at the highest speed.
The Tri-Cools are very nice, but like the previous posted said. At full speed, they are hellishly loud for 120mm fans. What i did though is put them at the highest speed and then plugged them into my fan 5.25" bay fan controller. That way i can vary the speed from about 1000RPM all the way to the max 2000RPM without having to open my case.
::EDIT::
also, you should look here. This was a thread made a while ago that was VERY active for some time, but recently sort of died. Its a very good source of exactly what you are looking for possibly.
