Greater than one weekSuper produit à la hauteur de la marque. Jai apprécié le système de branchement rapide qui évite le dénudage et lutilisation dun fer à souder.

Greater than one weekFan looks to be great quality. I upgraded a Kenwood TM-V71A radio that is used for APRS. Bc of the house layout, the radio is under our dresser in bedroom with coax running up through wall. The previous fan was so loud my wife said to turn off the radio. The new fan is a big improvement, although can still be heard a bit. It’s not library quiet like I’ve seen in other reviews though.

> 3 dayI ordered this fan to replace a noisy case fan on a Q-See QT8516 NVR. Installation took about 5 minutes. I used the enclosed silicone fasteners instead of the screws to help eliminate any vibration noise. Plugged the fan into the motherboard with the provided adapter and the fan worked. I had to put my hand next to the fan to make sure it was running because there was absolutely no noise. A remarkable difference from the stock fan supplied with the NVR. 100% happy with this product.

> 3 dayVery nice and quiet. Used these in a push and pull configuration to upgrade my old 3d printer fans. These work great. They perform on par with the old fan (I dont know the model) on volume of air coming through but the noctua fans are dead silent while the old stock fan could be heard on the second floor of my house while my printer is in the basement. Very happy with the purchase. Noctua never disappoints.

14-11-2024I installed this little fan in a Nintendo GameCube as the stock fan was getting a bit past its life span and sounded like a jet engine.

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.
