Dear customer,
Thank you very much for choosing the the Noctua NH-U14S.
The NH-U14S is the first 140mm model in Noctua's
award-winning NH-U series. First introduced in 2005, the
NH-U series has become a standard choice for premium
quality quiet CPU coolers and won more than 400 awards
and recommendations from leading international hard-
ware websites and magazines.
Enjoy your NH-U14S!
This manual will guide you through the installation process of
the SecuFirm2™ mounting system step by step.
Prior to installing the cooler, please consult the compatibility
centre on our website (ncc.noctua.at) and verify that the
cooler is fully compatible with your motherboard.
Please also make sure that your PC case offers sufficient
clearance for the cooler and that there are no compatibility
issues with any other components (e.g. tall RAM modules).
Double check that the heatsink and fan clips do not make
contact with the VGA card, other PCIe cards, motherboard
heatsinks or any other components.
Noctua cannot be held responsible for any damage or losses
caused by compatibility issues.
Should you encounter any difficulties, please check the FAQs
on our website (www.noctua.at/faqs) and don't hesitate to
contact our support team at support@noctua.at.
