This manual will guide you through the installation process of

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

on your CPU, please clean them off first. Then press a small
drop (3-4mm diameter) of NT-H1 onto the centre of the heat-
