The Geräsuch caused by the air flow can not be as
whisper call. While in the cold operating state of the fan
still quite silent running (because of the low speed by
the temperature-dependent PWM speed control), the fan rotates in
operation more and more and is not unangenem -
but very clearly audible. And I do not even use overclocking !!!
Why is the Arctic Cooling hinbekommt not better beyond me,
especially since they are long enough in the business. The front fan in the housing
rotates at about the same rate and is absolutely noiseless.
Even the also temperature-controlled stock Intel fan (boxed
CPU) is available in the second computer is compared with the Arctic Alpine 64
silently.
Three points for the fact that he is a lot better than definitely the AMD
Fan, who was installed previously. But in terms of volume, this
CPU fan only standard that other manufacturers can also (and
maybe even better).
