Product Reviews
- “Easily the quietest I've tested (and I've seen and heard everything from Antecs to Sunons, YSTechs, Panaflos and even Radio Shack howlers). Up to this point, the Panaflo has been my favourite for noise, but this fan is much quieter.” (AcoustiFan™ DustPROOF)- Virtual-Hideout.net
- “AcoustiFan DustPROOF fans are incredibly quiet. With the ability to protect the motor from dust, they will certainly last longer, possibly making them worth the expense”- A True Review
- “The fans felt solid and heavy compared to the stock fans I am replacing. AcoustiFan has designed these fans to last.” (AcoustiFan™ DustPROOF)
- “As far as performance, the DustPROOF fans I used both provided ample air flow, and without a doubt were much quieter than my cases stock fans.” (AcoustiFan™ DustPROOF)

Acousti AcoustiFan: DustPROOF 70mm fan
AcoustiFan™ DustPROOF - Premium Quality Quiet 70mm Multi-Purpose Cooling Fan
The fan motor for the DustPROOF range of virtually silent fans is extremely quiet. The AcoustiFan™ DustPROOF series use the highest quality double-ball bearings available for reliability, use-anywhere inside a PC for extra long life expectancy (upgrade your PC and take these fans with you!). One of the unique features of these PC fans is that the motor has been completely sealed from the outside environment. This prevents dust entering the motor and also reduces the amount of noise perceived to be coming from the bearings within the motor.
Each DustPROOF™ quiet fan is also supplied with a unique 3-speed fan cable which offers maximum flexibility (3-pin or 4-pin Molex power connectors), along with the ability to select a fan speed suitable for your PC and noise sensitivity. The black connector will run your fan at full speed (12V), the blue connector will run the fan at medium speed (7.5V), and the white connector will run it at minimum speed (5V). However, if you opt for the white connector (minimum fan speed), be certain to design the airflow through your PC system carefully and monitor system and component temperatures. Acousti have even included four handy cable ties with each DustPROOF™ fan!
The DustPROOF™ quiet fans also incorporate an Auto Start safety feature. This feature is built into the fan's PCB and automatically restarts the fan after the release of any obstacle which has prevented the blades from spinning.
For minimum possible noise, please consider using this fan with a 70mm AcoustiFan Gasket to dampen any remaining noise and vibration.

I bought this fan to replace the fan on the stock AMD CPU cooler for my Athlon x4 640. The AMD PWM controlled fan was efficient but irritatingly noisy under load. The DustPROOF fan runs on full speed all the time and keeps the max temperature steady on 59 degrees Celsius under full load, over many hours. So the air flow is not as good as the AMD fan, but sufficient.
Even at full speed, this fan makes about the same noise as the AMD PWM fan at its 2-3 lowest RPM levels. The only downside is that the fan is not PWM controlled. The noise from my PC is now dominated by the PSU fan, while this CPU fan is slightly more noisy than the two ACE Frost pro cabinet fans, mostly because the sound is a bit higher in the frequency spectra. All in all a great fan for an acceptable price. On lower RPM this fan is very quiet.
