A good black 120mm fan?

[EntosBox]

Hello! I was just wondering what would be some good options for 120mm fans that are black (Airflow oriented). I was hoping just to get two of them, and mount them as bottom intakes. I was thinking along the lines of the Corsair AF120 Performance Editions as a dual pack for $24, but I'm not really familiar with many case fans. Help is appreciated!

I have one same fan which comes with my case and it's really silent and moves a lot of air, for just 13$ you get 4 of them
