Many of my friends think "Micro Cooling Fan" in the framework of fixed fan only played a role, and therefore there will not be much difference. But the fact is there is because the fan itself vibration and many other issues, so one has a good fan frame design can effectively reduce the noise generated by vibration, etc., to bring a better acoustics. In addition to "Micro Cooling Fan" itself uses shock absorption design, the chassis still use some method of damping rubber nail side fan mounting holes on the fan directly to reduce vibrations caused by noise problems. As a result, even when players use no damping design "Micro Cooling Fan", it can also play a very good acoustics.
