I have been trying to find the best balance between noise and performance for 120mm and 200mm case fans. After a few days of researching, I think I am sold on the Cooler Master Megaflow for the 200mm but I am still lost with the 120mm. My config consists of two 200mm fans and one 120mm fan. I narrowed my choices down to the Enermax T.B.SILENCE and the Silverstone Air penetrator. I am not sure if there are better choices out there for the 200mm and the 120mm so I was wondering if I could get some feedback on some fans. I prefer to have red led fans but it is not required. I will take performance over aesthetics most of the time.
