Acousti AcoustiFan: DustPROOF 120mm fan
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.

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.
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?)
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.
