RotoSub and Noctua announce
partnership for PC fans with integrated Active Noise
Cancellation
Linkoping / Vienna, May 29th 2012 - Noise reduction
specialist RotoSub and renowned quiet cooling fan
manufacturer Noctua today announced a strategic partnership
agreement for the development and commercialisation of PC
fans with integrated Active Noise Cancellation (ANC). A first
prototype of a Noctua fan with integrated RotoSub ANC
technology will be shown at Computex Taipei next week.
Active Noise Cancellation (also referred to as Active Noise
Control or Active Noise Reduction, ANC) is the technique of
using sound waves to reduce noise by means of an effect
called phase cancellation or destructive interference. Lars
Strömbäck and Mårten Oretorp from RotoSub have invented a
system (RotoSub Active Noise Control, R-ANC) that allows a
fan to emit the sound signal that cancels out the original
sound of the fan and thereby greatly reduces the overall
noise emission.
“Mårten Oretorp and Lars Strömbäck's invention is a milestone
in the field of noise reduction”, says Mag. Roland Mossig,
Noctua CEO. “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's patented ANC technology makes it possible to
achieve performance/noise ratios that cannot be accomplished
by means of conventional aerodynamic or acoustic
optimisations. The licensing agreement with RotoSub will
allow Noctua to strengthen its position as a forerunner in
quiet PC cooling by pioneering PC fans and CPU coolers with
RotoSub ANC technology.
“Noctua is widely recognised as a leader in quiet PC cooling,
so they were the obvious candidate when we were looking for a
partner to commercialise the technology we've invented”, says
Lars Strömbäck, RotoSub CEO. “The performance and quality of
their fans is one of the best in this industry and their new
NF-F12 fan with its FocusedFlow system is ideal for
integrating our ANC technology.”
Introduced in late 2011, Noctua's NF-F12
FocusedFlow™ fan has quickly built up an excellent
reputation for its superior quiet cooling performance and
received more than 120 awards and recommendations from
international hardware websites and magazines. The new joint
development project with RotoSub pursues the ambitious target
of providing another significant step up in performance.
“Our performance target is to achieve about 80% more airflow
and 120% higher static pressure at the same noise level as
the original NF-F12”, explains Mårten Oretorp, RotoSub
CTO. “There is still a lot of fine-tuning to be done, both in
structural design and as far as the algorithms that compute
the anti-noise signal are concerned, but we're working hard
to achieve this goal within the next 12 to 18 months.”
A first working prototype of a Noctua NF-F12 fan with
integrated RotoSub ANC technology will be exhibited at
Computex Taipei (June 5th to 9th 2012) at Noctua's booth
(Nangang Exhibition Hall 1F, booth J1312). Noctua and RotoSub
kindly invite everyone to visit Noctua's booth to witness the
world's first public demonstration of a PC fan with
integrated Active Noise Cancellation.
