Warranty, Support and FAQs
1.
Connect the fan to the mainboard’s CPU fan header. Depending
on your CPU and the temperature inside the case, you may
interconnect the supplied NA-RC7 Low-Noise Adaptors (L.N.A.)
in order to further reduce the fans’ 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
cooling performance is insufficient, please increase case
ventilation or remove the L.N.A.
Adding a second fan
The NH-D9L includes an extra set of fan clips and anti-vibration
strips for installing a second NF-A9 fan to the front fin stack in
push/pull mode in order to further improve cooling performance.
The y-cable supplied with the retail NF-A9 fan can be used to
control the speed of both fans via the same mainboard fan header.
