Be Quiet! BL039 Pure Wings 2 PWM Case Fan, 12cm, Rifle Bearing

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 120mm PWM model combines all of the above essential features. It provides maximum cooling airflow and operating noise levels down to a silent 20.2dB(A). The increased air pressure makes the fans especially recommended for use in water cooling and air cooling setups.

Practically Silent Operation

• Nine 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 20.2dB(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
