Product Overview Variable, Virtually Inaudible, State Of The Art Cooling
The SilentWings 2 fan family provides the greatest airflow-to-noise ratio and highest reliability on the market. Key to these fans’ unrivalled and uncompromising performance are a unique airflow-optimized fan blade design, custom anti-vibration mounts, and a high-tech fluid dynamic bearing with copper core that greatly reduces noise and imparts super-long life. Through this advanced technology these fans achieve virtually silent operation without sacrificing airflow, and so offer the perfect balance between superior cooling and serenity.

The newest member of the family, SilentWings 2 PWM, adds variable-speed capability to this formidable combination of features and abilities. Just connect one to the PWM header on your mainboard or fan controller to achieve fine control over the fan speed and noise profile.

The SilentWings 2 PWM 140mm model is the largest fan we make that combines all of the above class-leading features. It provides maximum cooling airflow and operating noise levels down to a virtually silent 16.4 dB(A). Features • Unique airflow-optimized fan blade design reduces noise-generating fan turbulence.
• Advanced fluid dynamic bearing providing for greatly reduced operating noise.
• Improved modular vibration damping mounts and rubberized frame help prevent transmission of vibration to computer case and its components.
• Option for direct hard mount when preferred.
• Advanced high quality IC motor controller reduces electrical noise.

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.

Engineering
• Advanced fluid dynamic bearing (FDB) with industrial grade lubricant eliminates direct contact between rotor and frame, resulting in extremely low noise levels.
• The FDB has a copper core that conducts heat away from the bearing more effectively, enabling super-long fan life of up to 300,000 hours.
• Dynamically balanced fan blades enhance reliability and result in maximum operating silence.
• German product conception, design and quality control.

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by quiet fans... need i say more? after being traumatised by the drone of the supposedly "silent" corsair af140s, I tried these out. Not entirely sure if there is some sort of witchcraft involved here, or if corsair are just plain bad at making fans, but these are in a totally different league. At full tilt they do hum a bit but at anything lower than 90% the fan noise just disappears into a hushed whisper. Combine these with a decent sound dampened case and its actually quite difficult to tell if your pc is running or not. Strange mounting system but in my opinion its far better than screws. Zero chance of being talentless enough to accidentally break a fan or cross a screw thread. As far as im aware they have quite low static pressure so best to use them as simple air movers rather than radiator cooling fans, but for this particular job they are absolutely brilliant. Scan service and delivery top notch as always 14 April 2016
Rated 5 out of 5 by Great product Very simple to install & nice and quiet. Will definitely buy some more to replace the rest of my case fans. 21 January 2014
Rated 5 out of 5 by Expensive for a fan but the premium tag shows. Great fan for moving air, not ideal for radiators. They make the perfect case fan, completely rubber isolated, Silent, good performance and they look great. A premium price tag but the quality shows. Personally using these as my case fans, with NF-f12’s hidden away on my rad. 04 November 2013
