PURE WINGS 2
140mm PWM
Outstanding price-performance ratio
Pure Wings 2 140mm PWM fans bring famous be quiet! silent cooling to entry level computing, yet are also appropriate for gaming and multimedia systems.
- 9 airflow-optimized fan blades reduce noise-generating turbulence
- Long life rifle-bearing gives an operating lifetime of 80,000 hours
- Even at maximum speed, operates at only 19.8 dB(A)
- PWM controlled fan speed through the motherboard
- German product conception, design and quality control
Pure Wings 2 140mm PWM fans offer outstanding reliability and quiet operation at great price-for-performance ratio. They are the ultimate reason to put well-known be quiet! silent cooling in your PC.
VERY QUIET OPERATION
Achieves a great price-for-performance ratio
The Pure Wings 2 140mm PWM fan operates at only 19.8dB(A) even at maximum speed. The perfect choice for silent home and office PCs as well as gaming and multimedia systems.
SILENCE-OPTIMIZED FAN BLADES
For even better cooling
Thanks to its surface-optimized fan blades the airflow is enhanced, noise-generating turbulences are minimized and the air pressure is increased. This feature is the key to effective cooling.
VARIABLE FAN SPEED FUNCTION
Varies the fan speed and noise level of the fan
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. This feature especially recommends the fan for heat sinks and radiators.
RIFLE BEARING TECHNOLOGY
Gives the fan a very long lifespan
The Pure Wings 2 140mm PWM is the hallmark of outstanding reliability. This is achieved by its high-quality rifle bearing technology, which assures a very long lifespan of up to 80,000 hours.
