Attaching the fan
Step 6:
First stick the 2 anti-vibration strips onto the cooling fins in
order to dampen minor vibrations emitted by the fan.
Align the mounting holes of the fastening brackets with those
of the mounting bars. Now screw the fastening brackets to the
mounting bars employing the pressure springs and the respec-
tive screws
Caution: Tighten the screws until they stop.

Even with high-grade products and strict quality control, the
possibility of defects cannot be eliminated entirely. Therefore,
we aim at providing the highest possible level of dependability
and convenience by offering a warranty period of 72 months
and direct, fast and straightforward RMA service.
In case of warranty, you can either request RMA at your retailer
or use our Direct RMA Service. For further information, please
consult www.noctua.at. In order to process your RMA enquiry,
we need a proof of purchase, so please don’t forget to keep
your invoice!
Please also note that any modifications to the cooler, fan or
mounting parts will void your warranty.

Support & FAQs
Connect the fan to the mainboard, power supply or fan control-
ler. Depending on your CPU and the temperature inside the
case, you may interconnect the supplied Low-Noise Adapter
(L.N.A.) or Ultra-Low-Noise Adapter (U.L.N.A.) in order to
further reduce the fan’s operating noise.
Caution: When using the (U.)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 (U.)L.N.A.
Then attach the fan to the heatsink using the 2 steel clips,
placing it so that it blows onto the heatsink (You can optionally
use the second pair of clips to install a second fan).
