    Superb cooling fans.

    At first, I didn't believe the 'hype' about these fans being 'silent'. I've used fans for many years now and many of them confess to being quite. These Noctua fans take it to a different level. Moving air is inherently noisy no matter which way you look at it, but those people in R&D need a clap! I've exchanged all my NOISY fans in my 3d printer and now, i could probably run a print job in a library !! The price seems 'steep' for a small 40mm fan, but my word they are outstanding. Also, included in the price you get all the mounting kit you could ever need, along with an abundant array of cables. Well done Noctua.

    Very quiet replacement fan

    I used this to replace a fan in my Creality CR-10 controller box. Now I need to get a replacement fan for the hotend, as the box no longer sounds like a jet engine.

    Made my 3D printer quiet

    Bought for a 3D printer which had loud fans. These are hugely expensive, but hugely silent, especially if you use the silent adapter. Worth it for me, I hate loud fan noise.

    Pricey, but does its job

    It is pricey, but it does its job perfectly. My 3D printer is a lot quieter now. The product comes nicely packaged and has a few cabling accessories for different connecting options. Got a similar one on my Octopi that has been running non stop for more than a year without issue.

    Great 40x20mm FAN

    Doesn't produce much pressure but still good candidate if you want quiet replacement for your noisy 40mm fan.
