We have developed PC cooling fans that are truly ultra-quiet in operation and superb quality. We trust you'll be as pleased as we are with them. There are now a lot of brands claiming to have 'quiet' or 'stealth' PC fans - but we have been typically VERY fussy about noise levels in our research & development! All our PC fans do NOT tick at slow speeds, and they have very little high frequency motor whine at full speed. The quality build and balance in these quiet fans also means they don't excessively vibrate & generate even more noise!
AcoustiFans have NOT been designed for maximum airflow performance, but rather for ultra quiet operation (although the CFM airflow specifications are still very respectable). The ultimate solution for a near-silent PC system is adequate airflow to maintain low system and component temperatures but without excessive fan noise and vibration. These quiet PC fans are not designed for 'extreme' or 'overclocked' systems with a particular need for high airflow, but rather for systems where several well positioned ultra-quiet fans, each with a relatively slow RPM, will be more than adequate for cooling purposes. This is why all our PC fans start as low as 5VDC for virtually silent operation.

"Regular case fans cost only a few pounds but if you get a particularly noisy one it can make your PC sound like a vacuum cleaner.
"QuietPC AcoustiFans are specially designed for quiet operation...
"The AcoustiFan is almost silent apart from a very low purr, while cheaper alternatives hum and can be audible from the other side of the room. If you need more powerful cooling 92mm and 120mm fans are also available." Awarded 5 Stars
