> 3 dayWorked great for my Hikvision DS-7608NI-E2 NVR to replace the loud stock fan. Came with an adapter that allowed an easy plug and play, no soldering required.

> 3 dayAmazing fan. This thing is super quiet. I bought it to replace a 40mm fan in my 3D printer, and I couldnt even tell this thing was spinning when I powered it up the first time. I thought something was wrong, but it was working just fine. Thats how quiet this is. With my old fan, the fan noise was the primary sound you heard when the 3D printer was running. This fan makes my stepper motors seem extra loud, but in reality Im just taking the constant fan drone out of the picture.

> 3 dayI was working on an ACER desktop. BIOS had SmartFan application. CPU was running at 94 degrees Celcius. Replaced the heat sink grease. Still hot CPU. Turned SmartFan off in BIOS. SmartFan no longer reduced the 5volt CPU fan speed, but it did turn off the CPU fan after some minutes. The CPU fan connector is 5volts, the case fan connector is 12volt. The solution - this 12volt fan mounted on the CPU heat sink and powered by the motherboard case fan connector. Case fan is not controlled by SmartFan app. With this 12volt fan the CPU is running at 47 degrees Celsius; same programs running in each test. And the fan is so quiet, you do not know it is running constantly.

> 3 dayToo expensive, but it seems to work great in my 1U Supermicro power supply, the old fan sounded like a jet engine and this new fan is quiet but still pushes enough airflow to keep the server cool

> 3 dayI used this fan to replace a failed stock fan in an ICY Dock enclosure. The included accessories contain everything that is needed to adapt this to the old fans connector and the anti-vibration mounts fit perfectly as replacements for the screw holes that were previously used to secure the fan into place.

> 3 dayI am a Noctua fan, and own many different models of their fans. I used this fan to replace the dreadfully noisy fan in my Lorex security system. This fan, with the low noise adapter did not disappoint. Highly recommended.
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.
