be quiet! Pure Wings 2 92mm BL045 Cooling Fan

Seven airflow-optimized fan blades that reduce noise-generating turbulence. Air flow - 33.15 CFM. Noise level - 18.6 decibels.
Long life rifle-bearing gives an operating lifetime of 80, 000 hours.
Even at maximum speed, operates at only 18.6Db(a).
Especially recommended for use in air cooling setups.

Exterior : SFL (Super fiber Laminate). This is the basic Arai outer shell and is therefore sometimes referred to as ‘Standard fiber’ although it actually is Super fiber. Super fiber provides more comfort than other shell materials, yet is still strong and lightweight. / Ergonomic shape. The natural shape of the outer shell lends the Arai helmets a more homogeneous look, ensures greater sealing and better fit on the head, for improved comfort and wearability and minimized turbulence..
Interior : Facial Contour System (FCS). A foam spring support in the cheek pad that compresses and rebounds makes putting the helmet on easier. The cheek pad wraps under the jaw- and cheekbone instead of mostly on the soft cheek area. FCS offers a looser fit with secure support over a larger area providing superior stability and comfort with minimal pressure. / Central liner is thinner.
Visor : VAS Visor (patented) with V-shield base plate, 5mm longer and 10mm wider than the previous model.
Features : FFS (Free Flow System). Creates airflow under the helmet that reduces wind noise and turbulence while increasing the exhaust of hot air. / Spaces for speakers / Front Duct, Rear Ducts, side ducts, Browvents, Chinvent.

Automatically purifies and cools you. Automatically senses, captures and traps pollutants for cleaner air..
360° filtration system uses a HEPA filter to capture 99.97% pollutants as small as 0.3 microns..
Choose between Fan mode for direct cooling with your choice of 0 to 350° oscillation and Backwards airflow mode to purify without cooling..
Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model..
Air Multiplier technology generates the circulation power to draw distant pollutants into the machine, projecting purified air throughout the whole room.¹.

High static pressure cooling with LED illumination. Air flow – 49.49 CFM. Noise level – 29.3 decibels.
Tuned for high pressure air delivery directly to components.
Better performance than standard case fans.
LED-lit translucent, frosted fan blades for a dramatic effect.
Specially designed fan blades and a sleeved bearing system for less vibration, noise and turbulence.
