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.

possibility of defects cannot be eliminated entirely. Therefore, 
we aim at providing the highest possible level of dependability

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.
