Extremely quiet! But will it remain quiet for all 30000 hours?

Summary: Ordered two of these for an older Mini ITX - Atom 330 based Shuttle machine. The PS is external, the only fan in the case (a 40x40x10 attached to the north bridge heat sink) was well past its prime. I had already added an additional 40x40x20 fan on the wall of the case - but that SUNON model was about 3 times as loud as these fans with the same air flow. I ripped out the old units and installed two of these. WOW! Decent air flow without any of the noise. Very pleased!
Summary: I purchased three of these 40mm fans to replace three noisy fans in a 24 port Netgear port smart switch. These fans, do not come with the third wire for variable control, so they run at maximum rpm all the time. Even with three of them, my switch almost sounds fanless. If your fan does not power up initially, make sure to check and move the initial pin configuration around.
Summary: I purchased 2 for my VRM's on my motherboard as I was going to Water cooling and still needed to move air across them. The move less air than I thought they would but I don't hear them at all so I'm ok with it. The two of them keep it under 140F with an infrared thermometer. My 220W CPU pulls a lot of power and haven't had any issues.
Summary: I bought this fan to replace the whiney one that came with an ASUS C8MH70-I. This fan is much quieter, but since it is natively a 2-pin fan, the motherboard doesn't see it when connected with the 3-pin adapter. The result is that I need to go to BIOS/EFI each time to bypass the fan error. Hopefully I don't have to restart this computer very often.
Lovely silence in Wagan 400 Watt inverter (EL2003-5)
24 May 2014
Summary: High quality fan, very quiet and does move air! Replaced the 40 mm fan in a Wagan EL2003-5 400 Watt Inverter Inverter is now completely silent, here is how I did it: 1. Unscrew the two recessed Phillips screws on each black end 2. Gently pull away/out the black plastic ends so they are free from the white metal case, do not pull hard as they are wired in 3. Use a vise or large C clamp and gently squeeze in the curved sides of the white metal case 4.
