Fan Setup
Step 5
Connect the fan to the mainboard’s CPU fan header.
Depending on your CPU and the temperature inside the case, you
may interconnect the supplied NA-RC7 Low-Noise Adapter (L.N.A.)
in order to further reduce the fan’s operating noise.
Caution: When using the L.N.A., check the temperature of your
CPU using appropriate software (e.g. the respective applications
of your mainboard manufacturer), in order to evade automatic
throttling of the CPU due to the increased temperature. If the cooling
performance is insufficient, please increase case ventilation or
remove the L.N.A.
Adding a second fan
The NH-C14S includes an extra set of fan clips for installing a
second NF-A14 fan in push/pull mode in order to further improve
cooling performance.
The y-cable supplied with the retail NF-A14 PWM fan can be used
to control the speed of both fans via the same mainboard fan
header.
For best performance to noise efficiency in dual fan mode, Noctua
recommends to run the top fan at 1200rpm or lower (using the
supplied Low-Noise Adaptor).
Caution: Tighten the screws until they stop.
Fastening the heatsink to the CPU
Caution: Please first take off the protection cover at the bottom
side of the heatsink.
Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars. Note that you can reach through
the blades of the fan(s) using the supplied screw driver. There is
thus no need to take off the fan(s) for installation.
Step 4
Fan Configuration
The NH-C14S ships with the fan installed underneath the fins (low
profile mode). Alternatively, you can take off the fan and install it on
top of the fins to make more room for tall RAM or other components
(high clearance mode). Note that the NH-C14S will provide best
performance to noise efficiency in high clearance mode.
You may also add a second NF-A14 fan (optional) using the supplied
extra set of fan clips in order to create a dual fan configuration for
further improved performance.

Even with high-grade products and strict quality control, the
possibility of defects cannot be eliminated entirely. Therefore,
we aim at providing the highest possible level of reliability and
convenience by offering a warranty period of 6 years and direct,
fast and straightforward RMA service.
Should you encounter any problems with your NH-C14S, please
don’t hesitate to contact our support team (support@noctua.at).

Warranty, Support and FAQs
As it is not possible to reliably calculate or control the forces
that act upon a system during transport (e.g. in shipping), we
generally recommend, for safety reasons, taking the cooler off.
Noctua cannot be held responsible for any damage that may arise
due to excessive stress during transport if you keep the heatsink
installed.
Should I take the cooler off before transporting
my system?
