Then attach the fan to the heatsink using the 2 steel clips,
placing it so that it blows onto the heatsink.
Connect the fan(s) to the mainboard, power supply or fan con-
troller. Use the supplied y-split cable to connect both fans to
one fan header. 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 or-
der to further reduce the fan’s operating noise:
Caution: Please use one adaptor per fan when running two
fans with adaptors. Never use one adaptor for two fans by
putting it before the y-split cable.
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.
