Applying thermal paste
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first. Then press a small drop
(4-5mm diameter) of NT-H1 onto the centre of the heatspreader.
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!

Warranty, Support and FAQs
Connect the fan to the mainboard.
Depending on your CPU and the temperature inside the case,
you may interconnect the supplied NA-RC7 Low-Noise Adaptor
(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 cool-
ing performance is insufficient, please increase case ventilation or
remove the L.N.A.
In case you would like to use a 92x25mm fan for further improved
performance, please first unscrew the preinstalled NF-A9x14 fan
and use the supplied longer screws to install the 92x25mm fan.
