AcoustiFan AF80CT
(Page 1 of 5 )
The AcoustiFan being reviewed today, the AF80CT, is an 80mm "smart fan" priced at $16.95 (from QuietPC.com). Its fan speed is totally self regulated, controlled by a thermal sensor mounted on the end of a wire, which can be positioned basically anywhere. The fan also comes in 120mm and 92mm sizes. Other features include four gel-like mounts which help reduce vibration when the fan is attached to a computer chassis, and an ultra quiet and low vibration fan motor.
AcoustiProducts, the "ultimate noise reduction solutions for the computer industry," is a company based in England and Wales. Its products are manufactured in the UK, then shipped to distributors and resellers. The only available vendor in the US is QuietPC.com. AcoustiProducts features three types of products: cases, fans, and soundproofing foam. They are also planning a precut AcoustiPack (soundproofing foam) for the VapoChill case and fixed-speed AcoustiFans.
Statistics
With a CFM range of 15.6 to 25.4, the AF80CT pushes a very low volume of air for an 80mm fan. However, these fans are not designed for high airflow performance, but instead quiet performance. If you're planning on overclocking, you probably won't be really interested in a fan like this, but if you're looking to reduce noise without too great of a decline in cooling, the AF80CT becomes a bit more attractive.
The following graph, pulled from AcoustiProducts website, shows fan speed versus probe temperature.
"Image showing the graphical results of 3 fan speed tests against temperature change of the fan thermistor (or temperature probe). The shaded part of the graph shows the region of plus and minus 10% for fan speed over the 'expected' operational temperature range between 25°C and 75°C. The graph shows fan speed is approximately linear between the minimum and maximum rated fan speeds, over the temperature range 25°C to 75°C."
