be quiet! BL040 Pure Wings 2 PWM - Case fan - 140 mm - Rifle bearing - 1000 rpm

The Pure Wings 2 family fans combine outstanding reliability, silent cooling, and a great price-for-performance ratio. It's impressive how much quiet technology the engineering team has crammed into these fans at this amazing price. They are the ultimate reason to put be quiet! silent cooling in your PC if you haven't already done so. The Pure Wings 2 PWM models combine all of the above essential features. They provide maximum cooling airflow and operating noise levels down to a silent. The increased air pressure makes the fans especially recommended for use in water cooling and air cooling setups.

Key Selling Points

• Silence-optimized fan blades with high airflow capabilities reduce noise-generating turbulences while increasing air pressure
• Very quiet operation even at maximum speed
• Pulse Width Modulation (PWM) allows compatible 4-pin controllers to intelligently vary the speed 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
• Especially recommended for use in water cooling and CPU cooling builds
• High-quality rifle bearing technology contributes to a very long lifespan
