a compact low-profile CPU cooler that combines excellent
compatibility, surprising efficiency and remarkable
flexibility.

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
