outstanding reliability and silent cooling the pure wings 2 family fans are unique in their class combining outstanding reliability silent cooling and a great price-for-performance ratio. it’s impressive how much quiet technology the german engineering team has crammed into these fans at this amazing price. they are the ultimate reason to put well-known be quiet! silent cooling in your pc if you haven’t already done so. the pure wings 2 80mm pwm model combines all of the above essential features. it provides maximum cooling airflow and operating noise levels down to a silent 19.2db(a). the increased air pressure makes the fans especially recommended for use in water cooling and air cooling setups. practically silent operation seven silence-optimized fan blades with high airflow capabilities reduce noise-generating turbulences while increasing air pressure very quiet operation even at maximum speed with noise of 19.2db(a) variable speed function pulse width modulation (pwm) allows compatible 4-pin controllers (including those built into many motherboards) to intelligently vary the speed (and thus the noise level) of the fan with pwm your system can ramp up the cooling when it’s needed or operate in maximum quiet mode when it’s not product conception design and quality control in germany perfect choice for home and office pcs gaming and multimedia systems especially recommended for use in water cooling and cpu cooling builds high-quality rifle bearing technology contributes to a very long lifespan of up to 80000 hours 3-years manufacturer’s warranty
