This is the second fan I had purchased from amazon. Now its blue led and it looks awesome side by side with the previous fan ( green led). Now its two circle fans installed on the rear side of my cabinet. Noise level is now quiet loud. But its ok for me now. Connected it with molex pin, so getting highest amount of airflow. Led looks bright and my cabinet looks awesome. Now IM looking for the red one and looking for a fan controller also. Bcoz in a pin drop silence room You will definitely hear the noise.My motherboard only had two three pin socket which are already preserved by two 90 mm fans. Anyways my Over all system temparature is now below 40c . So these fans are doing a great job. So if you are looking for a 120 mm fan with high airflow, bright led within a cheap amount of price range then go for this one.
