Good performance and "relatively" quiet

To generate a continuous flow of air in the housing lacked even a fan and as products from Scythe always have delivered to me a good performance, I wanted by the relatively favorable Scythe chassis fan, Kaze JYUNI PWM SY1225SL12H-P black again achieve a good result , In the product description is advertised that the fan airflow of up to 187.4 m³ / h and creates because I lack the necessary means I can refute this only assume that this is true at full power. But someone of this fan at full capacity, ie operating at maximum speed, has either a very noisy work environment or a big problem with his ears. In normal operation of the fan via a 4-pin PWM power supply to the motherboard, the fan is rarely loud, but I do not have enough of these connections and had the fan via a 3-pin power connector operate with an intermediate ancient Zalman Fan Mate 2 rumflog somewhere. Through the Fan Mate it was then possible to regulate the fan manually at the desired speed, or to the desired volume.

Apart from the noise generated at full load (therefore unfortunately no 5 stars) the Scythe chassis fan, Kaze JYUNI PWM SY1225SL12H-P is black really recommend everyone to the didnt PWM ports or a place in the fan control.
