This fan is perfect.
The Airflow (cfm) that this fan produces is very impressive. The Static Pressure, is not fantastic, but it's more than enough to be an effective heatsink fan. The Blue LEDs are very bright, and they illuminate the strips very well.
As for the noise, the reviews on here are wrong. Obviously, some people had a loose air filter or something, because this fan is literally silent. Unless, you move your ear right up to the fan, you can't hear it. Don't listen to those reviews. This fan is PERFECT. No noise, High Airflow, Pretty Good Static Pressure, Very Nice LEDs. For £6, this fan is the best fan out there. I promise.
