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 & Feedback

"I installed the 80mm fan naked [that means without a fan gasket we hope!] in a new case that I am building. I fired up the PC with the fan installed in the rear, exhausting air out of the back. The fan itself is very quiet when running without the resistor... These fans are nothing spectacular or flashy (which they don't need to be) they are a decent quality fan. [Acousti Products] has designed a fan that will make even the most finicky person happy to own one.

"I found the fans and the silicone gaskets work together very well to create an almost totally silent fan. I would recommend these fans and gaskets to someone looking to silence their PC a little more.
Pros: Good quality; Very silent; Included screws (both fan and gasket); Motherboard connectivity; Included resistor for slower fan speed. Cons: Price a little high on fans; Could have included a 3 pin to 4 pin molex adapter" Awarded 8/10. [read the full review]

[AcoustiFan C-Series™ 80mm] "I got the three 80mm AcoustiFans today and all I can say is WOW THEY'RE QUIET! I replaced the rear 80mm PAPST fan [that I had previously] and did not use the [optional] in-line resistor [that comes with the AcoustiFan] and put it's thermistor [the AcoustiFan temperature probe] in the top of the case near the PSU... I put two other 80mm fans in the lower front of the case and used the in-line resistors - these two blow over the metal sides of the HDD box... and boy does it make a HUGE difference!
I have a Lian Li 60 aluminium case and the rubber grommets and screws do not fit the small holes drilled in the metal but I still had the old mounting kits so reused them all and it has made an incredible difference to the noise in the room. My wife is REALLY impressed with the difference in the living room! An AMAZING product!" Daniel Coffey, Edinburgh, UK

[AcoustiFan C-Series™ 92mm] "Just installed [two] 92mm AcoustiFans into a couple of Dells (1 recent, 1 old), to great effect. They're superbly quiet. They may lead to more expense though, as now hard disk noise is much more apparent, as is the sound of my fridge, from the kitchen down the hallway!" James Ferguson, UK

[AcoustiFan C-Series™ 80mm] "I just tried your 80mm fan and it is the quietest fan I've heard. I put it up to the Papst 8412 and your fan is better all around. Thank for the great work on this fan." Mike Mierau, Apex Audio, Huntington Beach, CA, USA

"I just received and installed my AcoustiFan and I am amazed. The terrible whining noise from my old case fan that I've put up with for years is gone! I can't tell you what a joy this is, and for so inexpensive a price. Thanks a million!" Murray Dundas, Calgary, Canada

[AcoustiFan C-Series™ 92mm] "Just wanted to congratulate you on an excellent product. I've just installed one of your Acoustifan 92mm ultra-quiet fans in my Dell desktop, and the difference is staggering. The old fan was like an industrial turbine, the new one is almost completely inaudible. Keep up the good work." Andrew Whitechapel, UK

[AcoustiFan C-Series™ 120mm] "Good fan, no noise when undervolted" Sebastien, Canada

[AcoustiFan C-Series™ 120mm] "My brother was having temperature problems with his new PC so I bought him two of these. One for the front to pull in cool air and one in the back to push the hot air out. It worked like a charm and he was very pleased with them." Rickard, Sweden

[AcoustiFan C-Series™ 80mm] "Bought two of these, excellent, very very quiet" Thierry, UK

[AcoustiFan C-Series™ 80mm] "These fans are wonderfully quiet. To enhance the product, I would suggest packaging the fans and your Ultra-Soft Fan Mounts to allow for maximum silencing" Sujeeth, USA
