Enthusiast PC fan manufacturer Noctua has announced a partnership with RotoSub to produce fans with active noise cancellation technology. They two companies have already developed a prototype chassis fan that uses fan blade modulation and a series of stationary blades in addition to the moving fan blades to improve performance while keeping the noise down. The noise canceling fan prototype will be shown off at Computex 2012 in Taipei next month (booth J1312 in Exhibition Hall 1F).
In a recent press release, RotoSub and Noctua have announced a “strategic partnership” to develop and market a line of Noctua fans with a new noise cancellation technology from RotoSub. The technology in particular is called the RotoSub Acive Noice Control (R-ANC). It uses phase cancellation principles to cancel out the annoying hum (or whine in those smaller server fans that sound like jet engines) given off by the fans. The fans do this by slightly modifying how the blades spin using proprietary algorithms (hopefully they will release more information on exactly what is going on there), and by including physical features like the stationary set of fan blades behind the moving set of blades.
The prototype Noctua NF-F12 fan that will be on display at Computex 2012.
Mårten Oretorp, RotoSub CTO stated that the company is aiming to achieve 80% more airflow and 120% greater static pressure than the Noctua NF-F12 fan by incorporating the company’s ANC technology. Noctua is licensing the RotoSub technology, which is claimed to deliver better noise-per-performance ratios than can be accomplished by physical aerodynamic improvements alone.
Further, Noctua CEO Roland Mossig stated “it has always been our goal to push the boundaries of acoustic optimisation and this partnership will allow us to reinforce our technology leadership in the field of premium grade PC cooling equipment.”
RotoSub hasn’t detailed the algorithms but they do have hints of information on their page including a video demonstration of the fan and an animation that shows the “anti-sound” being generated by the fan itself to cancel out the annoying fan noises that it produces. The video can be seen below.
It is an interesting concept, and I hope that it works. While moving to watercooling has cut down on the number of fans I’m using in my desktop, it is still not anywhere near what I would call quiet. Stay tuned for more information once the prototype is shown off at Computex 2012.

Corsair announced earlier this week that the company is expanding their cooling options to include PC case fans with their new Air Series. They have been bundling fans with their self-contained water cooling units since their release, but they have been rebranded fans from other manufacturers. With the Air Series, Corsair has designed the fans in-house and then had partners capable of building the units actually manufacture them. The fans in the Air Series have been designed to balance airflow and quiet operation for enthusiasts that want cooling performance with consideration towards noise.
Corsair AF140 Quiet Edition
Currently Corsair is offering 120mm and 140mm fans which focus on either high static pressure or high airflow. They feature a hydraulic bearing system, rubber case mounting points, and a variety of colors to choose from including red, blue, and white colored rings around the fan blades.
Corsair SP120 Quiet Edition
The fans with AF in the model name are part of the high airflow subset and are geared towards moving as much air as possible through your case. There are two 120mm and one 140mm fan for sale at the time of writing. Corsair has designed the fans with thin custom molded blades for a fan that moves lots of air and can be installed in spaces as small as 3cm in depth.
Corsair SP120 High Performance Edition
Alternatively, Corsair is offering fans that deliver a high static pressure, which makes them ideal for pairing with watercooling radiators and air cooling heatsinks. These fans have “SP” in the model name, and are currently limited to two 120mm fans. The high static pressure is achieved by using seven wide blades and a custom molded enclosure.
The following chart from Corsair details the currently available Corsair fans.
|Edition||Description||Size (mm)||Noise (dBA)||Airflow (CFM)||RPM||Static Pressure (mmH20)|
|AF120 Quiet||Low noise, good airflow||120x25||21||39.88||1100||not measured|
|AF120 Performance||High airflow||120x25||30||63.47||1650||not measured|
|AF140 Quiet||Low noise, high airflow||140x25||24||67.8||1150||not measured|
|SP120 Quiet||Low noise, High pressure||120x25||23||37.85||1450||1.29|
|SP120 High Performance||High pressure||120x25||35||62.74||2350||3.1|
Ruben Mookerjee, VP and General Manager of the Components Business Unit at Corsair stated that "Many PC fans on the market are general purpose designs that not always suited to the task which they're assigned. We took our expertise in PC case and cooling and designed fans that have very specific uses. Each fan is the right tool for the right job."
The new Corsair Air Series fans are on sale now and carry an MSRP of $16.99 USD for the AF120/SP120 (120mm high airflow and static pressure) fans and $18.99 USD for the 140mm AF 140 fans. More information on the Corsair fans can be found here.

If you have a case fan you want to replace due to poor performance, loud operation or any other reason, NZXT has some nice new options for you. If you need 120mm, 140mm or even 200mm; their new offerings will meet your needs. Legit Reviews tested all three, the two smaller FX series might be a little noisy but they do deliver results. The large FS-200, if you can fit it into your case is much quieter and still pushes a serious amount of air. Check the full review here.
"For the first two products today, we have two of NZXT's newest entries to the cooling fan market; the FX Series of fans are Enthusiast grade products with Fluid Dynamic Bearings and high performance specs. With high RPM fans with huge static pressure and airflow ratings, NZXT's looking to capitalize on those who need well built, high performing fans for their multi-GPU or CPU cooling solutions. The FX Series of fans specialize in Airflow & Static Pressure allowing them to maximize the cooling potential of any radiator or heatsink. The FX Enthusiast Series fans from NZXT come with 3 speed, dip-switch controls to adjust fan speed between low (5v), medium (7v), & high (12v) settings. We'll be looking at both the FX-120 and FX-140 models in today's review, which is very exciting for me, as it's one of the few 140mm fans to come out in recent years that actually uses a standard 140mm frame instead of a custom design..."
