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 list
on our website (www.noctua.at/compatibility) 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 or other PCIe cards. 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 [e-mail].
