True to its name

Inaudible low speed and you have to strain to hear in high speed position, great efforts have also been made to prevent vibration (4 corners of flexible material yellow + 4 "screws" flexible mounting as well).

After one must not forget that even if the fan is very quiet the result obtained in the housing can be different (breath from the air flow passing through the gates of the enclosure).

The other by the TrueQuiet a rather average air flow (21.5 to 35.8 CFM (cubic feet / minute ... long live the Anglo-Saxon units)) over a little more high-end models is commonly one double, so for cool nicely without increasing the volume it will be perfect, but in case of over-clocking I think it is better to spend his way and move towards something more powerful.
