    It did not work out of the box in my Cisco switch. However it now works after switching connector pin order from B,R,Y to R,Y,B.

    Beh, che dire? Le ho montate sulla mia stampante 3d. Quando L accendo non si sente un minimo rumore. Costano ma ne valgono assolutamente la pena. All interno della confezione troviamo un sacco di cavi e altri accessori. Scatola premium. Per queste cose non bisogna badare a spese. Sono fantastiche

    I bought this to replace the noisy and failing hotend fan on my Creality Ender 3 Max 3D printer. The original started making noise after only a couple of months, I tweaked it a bit and it went away, but came back a month or so later, so after enduring the noise and rattling for a few more months I decided to replace it.

    Inudibile, solida e piena di cavi e gommini per il montaggio, però sposta davvero poca aria.

    Nice 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.

    As always with Noctua, outstanding performance/noise ratio

    Ive been a long-time fan of Noctua as the quality shines through (color scheme is another topic). The NF-A4x10s were used to cool multiple HBAs, specifically 2x LSI 9300-8is which connect 16x Samsung 860 EVO SSDs (for virtualization storage).

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 Channels

The 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 Bearing

The 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 Pads

Integrated 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 Microstructures

With 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.
