We all know that dust increases a fan's noise over time. Put that new quiet fan in, and a couple of months later it is a little louder than it used to be. That is why AcoustiFan has developed a dust free fan. It is designed to eliminate that gradual increase in noise over time of a fan. Quiet PC was nice enough to send us a couple for review.</p> <p align="center"><a href="atruereview/acoustifan/02.jpg"><img src="atruereview/acoustifan/02th.jpg" width="250" height="191" border="0" alt="AcoustiFan No Dust Quiet Fans and Other Quiet Cooling Products" title="AcoustiFan No Dust Quiet Fans and Other Quiet Cooling Products"></a> <br> <font size="-1">Click on image for larger picture</font> </p> <p><b>Packaging:</b></p> <p>Quiet PC shipped the AcoustiFans and some extra items (silicone fan gaskets in a plain cardboard box, surrounded by paper padding.</p> <p align="center"><a href="atruereview/acoustifan/01.jpg"><img src="atruereview/acoustifan/01th.jpg" width="250" height="183" border="0" alt="AcoustiFan No Dust Quiet Fans and Other Quiet Cooling Products" title="AcoustiFan No Dust Quiet Fans and Other Quiet Cooling Products"></a> <br> <font size="-1">Click on image for larger picture</font> </p> <p>AcoustiFan comes packaged in a cardboard box with the specifications on the front.
