I'm currently using several of Noctua's fans in various sizes; 120mm, 92mm, and this 80mm fan.
Noctua makes an excellent product, but they still can't overcome the immutable fact that smaller computer fans are noisier than larger ones. I installed two of these in push/pull configuration to cool the CPU in my mini tower. There is also a Noctua 120 in there as an active front intake, and one of their 92's for exhaust. All fans blow towards the rear of the case. At full RPMs, I can hear only the sound of air moving from the two larger fans, but there was a clearly audible low drone in the key of 'A', emanating from the center of the motherboard. Thankfully, that sound was easily quieted by using the included low noise adapter cable with its voltage reducing inline resistor, as well as 'SpeedFan' software. And my CPU continues to run at acceptably cool temps (40/55 Celsius for idle, and when under heavy load).
I love Noctua's stuff. And their 80mm fans are quieter than those of other manufacturers (I also own Rosewill, Cooler Master, Vantec 'Stealth' and Thermaltake's 80mm fans). But it is what it is. ALL 80mm fans whine at full RPMs. If you want dead silent, use a larger fan (preferably a Noctua).
