Are there any LED fans (preferably 4-LED) that are as quiet and perform as well as the L1A? I'm trying to remember, isn't the L1A is a good perfomer considering how quiet it is? So taking an LED fan that's, say 32 dB, and lowering it's speed to give 21 dB might not give the L1A's performance? Also lowering an LED's speed could make the LED's not work, correct?
