The single-colour Thermaltake Riings go okay, but steer clear of their RGB units - the controllers are rubbish (n=9). Riing with the (included) Low-Noise Adapter would serve you well in that case. That said, I run NZXT Aer RGB gear now and don't really recommend them, either (n=8).
Cougar make a nice FDB unit with various LEDs in 120mm, quieter at full-tilt than above (n=12). I think Phanteks do/did one, unsure whether they offered green specifically but their F-120SP fan is an excellent all-rounder, as is their F-140SP if you can fit it (n= way too many to count).
The CM SickleFlow recommended earlier is a good fan but a loud fan - couple it with an inline resistor of some description (or just feed it 7V) and it'll serve well, but they're very noisy at full-tilt - strange motor pitch (n=4). I notice there's a SickleFlow X around now - haven't tried that one.
Haven't tried the SilverStone one listed, either. Looks like it'd go alright with a resistor or 7V adapter, too - noisy bugger at full-tilt. Give the 'regular' Corsair fans a miss too - too noisy for the airflow, and the older ones have a PWM 'tick' at lower RPMs.
The alternative is RGB, and in that case I only have experience with Thermaltake and NZXT and recommend neither. Thermaltake cheap-out on their controller hardware (and their software is a bit buggy still), and NZXT's unorthodox fan design gives clearance issues when you mount the fan LEDs-in (I've also noticed they're not particularly well-balanced). The Aer gear also needs the HUE+ controller to change LEDs, driving up the cost (although the CAM software is excellent).
The newer Corsair maglev RGB gear looks okay but again at AU$80/fan they're dreaming. I'm also seeing In Win and AeroCool sets, but have no experience with those.
If the LED is optional, it'd be a Phanteks F-120SP all the way (unless you can find a Scythe Gentle Typhoon 1850). If you need the LED, a regular Thermaltake Riing in green with the LNA.
I spend way too much money and time on fans, sigh.
