Hello I want to know what is the best fan out there in terms of good airflow and low noise levels for a 120mm and a 80 mm case fan also want it at a good price. Any good recommendations?
Fans from Zalman are good (I recommend those). These fans are very silent, not expensive and blow a large amount of air.
Lower RPM Panaflow and stuff from the Vantec Stealth line would be considered if you want good airflow with low noise.
