> 3 dayFan does not spin on its own. Needs a tap to jump start it, so I wouldnt trust it if the device is power cycled.

Greater than one weekUnglaublich Hochwertig für dieses Geld! Sehr edel gestaltete Verpackung mit einer Menge Zubehör. Habe den lüfter an einem anycubic i3 Mega zur hotendkühlung verbaut, aus dem nervigen Drucken wird ein entspanntes Arbeiten! Empfehle aber zusätzlich noch den Lüfter für das mainboard zu tauschen.

> 3 dayNice quality which is often lacking in 40mm fans. Moves enough air but not loud at full speed. I am using these to push air out of that rear 5 wide grill area (right above he PCI slots) at the back of Sonata III cases. Now if someone would just make a nice duct that pull air up off of the PCI cards (they just dont exist - 3D printers will change this), wed have some really good cooling of PCI cards for cases of this type.

Greater than one weekThese went in my re-amiga A1500 case I bought awhile back. Fan size for the case was not listed anywhere, so glad they fit. The computer draws so little power that the psu fan wont kick on. I got these so the computer would get some airflow.

> 3 dayThe CPU fan on my Synology DS 411+ NAS drive was getting nosiy. This fan dropped right in and fit perfectly. Its whisper quiet too. The install is easy. Take the case off, remove all the hard drives and with a philiips screw driver, remove the 4 screws holding in the existing fan. Unplug it from the mother board. They supply all sorts of adapters and such, you wont need any of that stuff. Be sure to take notice of which way the wires are facing on the harness before you unplug yellow is towards the back. The plug is not keyed and you can plug it backwards. The new fan goes in the same place dont go too tight on the screws just snug them down. The other watch out is since these fans are not Synology exact replacements, you will get a beep code saying fan stops and start again. They never really stop though, I checked. You will have to disable the beep with a fan error in the software which is pretty easy. Good quality fans they work well and the install is a snap.

> 3 dayIts not that this is so quiet which surprised me, its how incredibly loud the one it replaced was. This fan is whisper quiet, and as far as I can tell performing as well if not better. The difference is like a water fountain, or Niagara Falls. A whisper, or a 3 year old screaming. At face value, youd think a fan is pretty much a fan, but clearly some are better than others. Very quiet. Second one I bought because the first worked so well.
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 FLX is a highly optimised, premium quality quiet fan in 40x10mm size. Smooth Commutation Drivetechnology and Noctua’s reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor and OmniJoin Adaptor Set, the NF-A4x10 is a premium choice for the highest demands.
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

|---|---|---|---|
Flow Acceleration ChannelsThe NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 BearingThe NF-A4x10 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Integrated Anti-Vibration PadsIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Reduced motor hub size
Thanks to its streamlined, compact motor design, the NF-A4x10"s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10"s superior airflow and pressure performance.
