AcoustiFan™ DustPROOF - Premium Quality Quiet 120mm 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.

(AcoustiFan™ DustPROOF)Virtual-Hideout.net
“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.”
A True Review
“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”
(AcoustiFan™ DustPROOF)Club Overclocker, Overall Rating 9.5/10
“The fans felt solid and heavy compared to the stock fans I am replacing. AcoustiFan has designed these fans to last.”

“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.”

Quiet
This fan turned my noisebox into a computer that I cannot notice whether it’s turned on or not. Thank you so much!
Now I have to get GPU fans to avoid noise when gaming. Gelid Icy Vision Rev.2 seems like the way to go.
Extremely quiet
I bought 2 of these and they are extremely quiet inside my Zalman case. I now need a quieter CPU fan as that is the noisiest component now. These fans are sealed too so should not get noisier in a few years time. So far so good. I bought the rubber mounting gaskets for them too, just to be sure I got no case vibrations. Worth it in my opinion as easier to use than those rubber golf tee mounts. (Btw, my fans all suck air out of the case. Blowing air into my case made a strange noise due to the air oscillating through the grilles? Might need to mount fans a good distance from the case grille to prevent that?)
Brilliant!
I have used quite a few of these and they are now my 120mm fans of choice. Very quiet and reliable. Worth paying that bit extra for quality fans.

FAQ
- How do I measure fan size?
The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.
As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.
Screw hole spacings and fan sizes

The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.
- How can I tell which way the air blows through the fan?
Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.
- Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?
Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.
The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.
Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.
