DustPROOF Series Technical Specifications

We are committed to publishing accurate and truthful noise level data - taken directly from acoustic testing reports to recognised International Test Standards. At 1m distance in the average home/office environment noise levels below 10dBA will be difficult to discern above normal background noise levels.

NOTES: * Where noise levels have been measured & calculated @1m distance below 10dBA we have quoted <10dBA. Very low noise levels, are taken at 0.3m distance and extrapolated to 1m, so that recorded levels are significantly above test chamber background noise levels. The quoted RPM for an individual fan may vary slightly by as much as 10% (figures shown are averages from multiple tests). A variation in RPM at a given voltage will result in a change in airflow and noise levels. * Auto-restart is a safety feature build into the fan's PCB that automatically restarts the fan after the release of a constraint that has prevented the blades from spinning.

Important Recommendations & Disclaimer

Adequate airflow is essential in the majority of computer systems. We recommend that system and component temperatures are tested and monitored carefully after the installation of our fan products (see our FAQs section for more information regarding monitoring system and component temperatures). We also recommend that the cooling system in a computer is designed to over-compensate slightly for necessary cooling, therefore building in a safety margin should a particular element (like a single fan) fail.

The design of an adequate computer cooling system is the responsibility of the system builder. Acousti Products do not accept any liability for component or system failure, or any associated data loss whatsoever due to over-heating or inadequate cooling. If you feel that you are not sufficiently qualified to modify an existing system, then seek expert advice and technical support from a qualified engineer. We recommend that system and component temperatures are tested and monitored after installation.

Reviews and Feedback

[AcoustiFan DustPROOF™ 80mm] "You're not paying for bling, you're paying for silence and longevity of usage... The AcoustiFan DustPROOF™ Ultra Quiet Low Vibration Cooling Fan receives a Gold Award (yes, silence is golden) and an Editors Choice Award."

Moditory.com - GOLD Award and Editors Choice Award "After taking everything into consideration, the AcoustiFan DustPROOF™ series is a pretty good buy. Keeping with the AcoustiFan legacy of dead silent performance, the DustPROOF fans life expectancy has been extended with the seal as well as dampening sound from the internal components even further. Silence comes at a price, each fan doesn't push as many CFMs as other fans. But with a proper fan configuration in your case cooling shouldn't be a problem.

"We recommend this fan to everyone who needs to replace that noisy, rattling fan, wants a quieter PC, and expects their fans to serve your PC for at least a system upgrade or two, if not longer." GOLD Award & Editors Choice [read the full review]

[AcoustiFan DustPROOF™ 120mm] "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 favorite for noise, but this fan is much quieter."

"Slowing a fan to lower its noise output is standard practice among modders, and it's nice to see that AcoustiFan has made this a plug-and-play affair.

" ...it needs to be used in a case where the airflow has been well thought-out and it shouldn't be relied upon to cool the entire case by itself. Use common sense. A non-overclocked machine running within specs should be just fine if everything has been well-designed for airflow and cooling.

"At 12 volts, there was a barely noticeable hum, and I mean barely noticeable. At 7.5 Volts, the hum disappeared, and at 5 volts I held the fan right up next to my ear and I couldn't hear it... The Acoustifan ultra-quiet [DustPROOF™] fan is indeed very quiet, the quietest I've ever (not) heard." [read the full review]

[AcoustiFan DustPROOF™ 80mm & 120mm] "[Acousti Products'] 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."

"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 [Acousti Products] has developed a dust free fan... Both [fans] are incredibly quiet when running in full mode, though, the 120mm does have a light hum to it when running at full speed. You have to be within a couple of feet of it to hear this hum... On the mid and low settings, I could not hear any fan noise. There was very little wind noise as well. Neither fan puts out a lot of volume; therefore, if you need strong airflow, these might not be the fans for you... AcoustiFan's No Dust fans are incredibly quiet. With the ability to protect the motor from dust, they will certainly last longer, possibly making them worth the expense.

Pros: Extremely quiet, Keeps dust out of motor, Long warranty, Comes with cables to control speed
Cons: Cables are not convenient when wanting to switch speeds, Expensive
Rating: Very Good" [read the full review]

[AcoustiFan DustPROOF™ 80mm & 120mm] "After firing the PC up, I had to check to make sure the fans were running at all."

Cluboverclocker - Recommended "The fans felt solid and heavy compared to the stock fans I am replacing. AcoustiFan has designed these fans to last. The DustPROOF™ construction means the fan is designed to keep harmful dust out of the motor, effectively keeping the motor quiet and prolonging its life...
The fans were inaudible over the system even at full load. I was initially concerned about a noticeable drop in airflow, but the total CFM reduction was not measurable in system temperature...
Although these little guys are not cheap, if you are tired of the constant droning, give these a whirl." Overall Rating: 9.5/10 [read the full review]

[AcoustiFan DustPROOF™ 80mm & 120mm] "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."

"Even when compared to the quietest Panaflo low flow fans, the DustPROOF fans look really attractive. Couple this with a 3 speed adjuster, as well as a 6yr expected lifespan and I believe these fans are a good choice for anyone looking for the quietest fans possible for their system."

[AcoustiFan DustPROOF™ 80mm & 120mm] "If you are looking for fans to get a quiet computer, then this is what you have been looking for, and for those of you who are looking for fans that transport a lot of air, then look no further."

"The most impressive thing with these fans is the DustPROOF feature. This solution protects the fan engine from dust and also filters away noise from the engine. It's almost impossible to find anything to complain about, except the price. Besides this all we can say is that these fans are top notch quality and the performance compared to the sound level is nothing less than excellent!" [read the full review]

[Review of Fan Gasket, Ultra-Soft Fan Mounts and AcoustiFan DustPROOF™] In this Mad Shrimps "120mm Fan Round Up" review the AcoustiFan performed very favourably against Papst, Artic Fan, Titan and Antec quiet PC fans - with the added unique feature that the AcoustiFan™ is dustproof. [See "120mm Fan Round Up" test results]

"Without a doubt the best system fan I have come across. I have 2 of these babys in my media centre, they work silently and effectively. Hats off to you guys." Paul, UK.

"I have 2 of these fans running quite well on a Zalman ZM-MFC1 controller 5-10.5Volt range. They work fine and produce very little noise." Steve, UK.

"As for the noise level, the overall project [Jonathan made a 'computer kennel' for his PC!] has made a big difference. I can now sit at my desk and hear low-level sounds on my monitor speakers, as well as recording acoustic instruments in the same room. The fan is supremely quiet. It begs the question why computer manufacturers don't use them in the first place." Jonathan, UK [AFDP-12025B with Silicone Fan Gasket]

"Excellent - totally quiet. I have highly recommended this company to my friends, it is excellent." Robert, UK.

"Perfect don't change a thing." Jennifer, Canada.

"These fans live up to their expectations and I plan on acquiring more of them in the near future. I used to have to talk over my computer, now I have a hard time telling if it's on." Alex, USA.

"I have purchased one of these as my room is really dusty and it really works well." Robert, UK.

"Added it to my old Antec case. Works great." Dennis, USA.

"I bought this fan earlier this month to improve airflow in the silent mATX case I had recently built. The purpose was to create a silent and cool PC. I achieved this using two of these 120mm fans and a pair of rubber mounts. I am very happy with them." Alexander, USA.

"It is the quietest fan I have used" Ben, UK.

"Really nice quality, and good airflow. It was so quiet I had to double check that I'd actually plugged it into the motherboard." John, UK.

"Real good fan, the best I have tried yet, silent with good airflow." Christoffer, Sweden.

"This is an excellent fan for case cooling. Even at full speed it is almost inaudible." Giannis, Greece.

"I just installed two AcoustiFans into a very noisy PC that I use as a security monitoring system. The 80mm 8025B with mounting isolators replaced the rear case fan and the 70mm 7025B replaced the CPU fan. The system is so quiet I can hear the disk's heads move. I no longer hear the screaming cheap CPU fan from the next room. Thank you!! The fans were worth the money." Craig, USA.
