Be quiet!, the market leader in PC power supplies in Germany for nine consecutive years, introduces the latest version of the Pure Wings 2 fans with PWM functionality. This allows for an even easier control of this proven entry-level fan and makes it suitable for a wide range of applications. The all-new Pure Wings 2 PWM offers the highest reliability and an extremely low noise level at an excellent price-performance ratio, just like the 3-pin version.

Be quiet! adds PWM functionality to the rock solid Pure Wings 2. This low-cost entry-level fan can easily be controlled over a 4-pin connector via Pulse Width Modulation, either automatically by the motherboard or manually through the BIOS or with the appropriate software. The flexible rotational speed of the new Pure Wings 2 is ideally suited for a wide range of applications and represents the ideal choice for air and water cooling setups. The fan can be mounted on the radiator, radiator body or in the case to support an optimum airflow.



Durable technology and optimized airflow
The Pure Wings 2 PWM is assembled with a durable rifle bearing which, together with a high-quality motor control, does not just provide a low noise level but also enables an operating lifetime of up to 80,000 hours. To drop the noise level even further, be quiet! utilizes airflow-optimized fan blades that reduce noise-generating turbulence to a minimum. The advanced IC chip isn't just very efficient, it has also been optimized for a low switching noise. Through all these measures, the Pure Wings 2 PWM is nearly inaudible even at maximum load: the fan generates (depending on its diameter) an extremely low noise level of 19.2 to 20.2 decibels.

Four models for a wide range of applications
be quiet! offers the Pure Wings 2 PWM in four sizes, with a diameter of 80, 92, 120 or 140 millimeters. The two smaller versions are working at 1,900 rpm. As for the 120mm and 140mm models, the rotational speed drops to 1,500 and 1,000 rpm, respectively. Due to the availability of different sizes, this new fan is optimally suited for use in HTPCs, multimedia and gaming systems, as well as high-end water-cooled configurations.

The Pure Wings 2 PWM is available immediately at a suggested retail price of €9.80/£7.99/$9.90 (80mm), €10.70/£8.99/$10.90 (92mm), €12.40/£9.99/$11.90 (120mm) and €13.40/£10.99/$12.90 (140mm). In early 2016, the fans also will be available in North America.

These are quite cheap though. I just wish they'd pad the corners with some silicone rubber. I'm kinda used to that with Noiseblocker, though their fans are quite more expensive...

No need if you use rubber grommets, and if a fan is screwed in the rubber be pointless anyways due to vibrations would just go though the screws lol.

cfm and static pressure ???

Yeah i wounder were that important data is.

Apparently the 120mm is only 1000RPm so yeah it should be pretty dam silent lol. Dam my Cougars are pretty much silent and a much faster RPM.

They also give a RPM/PWM duty cycle graph:

400 to 1500 rpm is a good range.
Witch is almost as good as the graphs that Artic cooling gives

Also worth mentioning that the "rifle" bearing is a FDB with another name, if the Internet is to be trusted.

You can always use rubber pins.

If these are anything like the other stuff they build then they are worth checking out

I wish to see a day when fan makers will engrave or paint their logo into the middle part of the fan with superior precision instead of using stickers that are in 99,99% of cases of center which not only looks ugly but also can't help the fan perform well in terms of vibrations and durability. Even if it's just a tiny thin like sticker, it's still an off center weight.
