Award-winning NH-U12 series
First introduced in 2005, Noctua’s NH-U12 series has won
more than 600 awards and recommendations from leading
international hardware websites and magazines. The
NH-U12A is the latest addition to this prestigious
series that has established itself as a benchmark for
premium-quality quiet 120mm coolers.
|
140mm performance in 120mm size
Thanks to its completely revised, thoroughly optimised 7
heatpipe layout, 37% more fin surface area (as compared
to the NH-U12S) and a dual fan push/pull configuration
that uses the new, state-of-the-art NF-A12x25 fans, the
NH-U12A pushes the performance envelope in the 120mm
class and can actually match or even outperform many
140mm sized coolers.
|
100% RAM compatibility on LGA115x and AM4
Due to its asymmetric design, the NH-U12A does not
overhang the RAM slots on Intel LGA115x and AMD AM4
based motherboards, which ensures easy access to the
modules and 100% compatibility with tall heat-spreaders.
On LGA2066, the rear fan will overhang the RAM slots on
the left-hand side of the socket, so RAM modules should
not exceed 42mm in height.*
|
Classic 120mm tower size for excellent case and PCIe
compatibility
Standing 158mm tall, the NH-U12A is short enough to fit
most modern mid- or high-end tower cases. Measuring
125mm wide (including fan and fan clips), the cooler
stays clear of the top PCIe slot on most standard ATX or
Micro-ATX motherboards, ensuring optimum compatibility
with multi-GPU setups.
|
Dual NF-A12 120mm fans
The NF-A12x25 is
a highly optimised next-generation 120mm fan that
integrates Noctua’s latest innovations in aerodynamic
engineering in order to achieve an unprecedented level
of quiet cooling performance. Using this elite-class fan
in a push/pull dual fan configuration is one of the
cornerstones of the NH-U12A’s commanding performance and
acoustic efficiency.
|
PWM support and Low-Noise Adaptors
The NF-A12 120mm fans supplied with the NH-U12A support
PWM for convenient automatic speed control through the
motherboard: full performance under load, virtually
silent at idle! In addition, maximum fan speed can be
reduced from 2000 to 1700rpm using the supplied
Low-Noise Adaptors for even quieter operation.
|
SecuFirm2™ multi-socket mounting system
Noctua’s SecuFirm2™ mounting systems have become
synonymous with quality, safety and easy installation.
Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155,
LGA1156) and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), as
well as AMD AM4, AM3(+), AM2(+), FM2(+) and FM1, the
SecuFirm2™ mounting included with the NH-U12A is
straightforward to install, provides perfect contact
pressure and will stand the test of time even under
heavy use.
|
Compatibility with past and future sockets
Thanks to Noctua’s SecuFirm™ ecosystem, the NH-U12A can
be made compatible with the older LGA1366 and LGA775
sockets using the optional NM-I3
mounting kit, which is provided free of charge. If
technically possible, Noctua will also provide upgrade
kits for future sockets, which makes the NH-U12A a safe
long-term investment.

NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a pro-grade TIM
solution that provides minimum thermal resistance,
excellent ease of use and outstanding reliability.
Chosen again and again by overclockers and enthusiast
users worldwide, it has established itself as a
benchmark for premium-quality thermal compounds.
|
Soldered interface between heatpipes and fins
With many heatsinks, the fins are press-fitted to the
heatpipes. Due to the different thermal expansion
coefficients of copper and aluminium, this fit can
loosen over years of thermal cycling, which may lead to
reduced performance. By contrast, the NH-U12A’s fins are
soldered to the heatpipes in order to guarantee a
superior thermal interface that doesn’t deteriorate even
after many years of usage.
|
6-year manufacturer’s warranty
Noctua products are renowned for their impeccable
quality and outstanding longevity. True to this legacy,
the NH-U12A heatsink is built to last, and like all
Noctua fans, the supplied NF-A12x25 units feature an
MTTF rating of more than 150,000 hours. The entire
package comes with a full 6-year manufacturer’s
warranty.

* In cases with more than 158mm CPU cooler clearance, the rear
fan can be moved upwards to make room for memory modules taller than
42mm.
