> 24 hourReplaced the OEM fan on my MB with this, temps improved and noise level went down. I would recommend this fan for replacing the assist fan on rear of a Z77 ASUS Sabretooth MB.

> 24 hourMy TiVo Roamio 35x35x10mm fan was failing regularly making a loud noise. The fans sold for a direct replacement were short lived, 2-3 mo. I took a chance on this fan even though it’s 40x40x10 mm size and 5 mm talker. The good news is it will fit if just set in place, no screws, with just thin 2 sided tape on the bottom to hold it in place 1/16 inch from the hole. The plastic tivo case top will bow but snap back in place with just a 1/4 in max gap at the back. Wow is it quiet! My TiVo cpu now rubs at 39-42C and so quiet! From many search reports, Noctua fans do run quiet and for long times I’m counting on. If it lasts a year vs 2 mo vs other fans $4 or $30) it’s well worth the $15 price! Hope this helps TiVo Roamio owners with another silent fan option now. It isn’t a direct fit, but it will fit good enough to snap the case cover on both sides. It’s been a month now and my TiVo temperature stays between 35 and 42c depending on room temperature and streaming or watching off the hard drive. Acceptable temperature range so far.

> 24 hourListen, this fan is amazing. Its small, quiet and great for any projects you need. The only problem is that mine came in used.

> 24 hourCon questa ventola, montata per raffreddare lestrusore di una stampante 3D, questultimo non riusciva a raggiungere le temperature sopra i 190 gradi poiché la ventola dissipava il calore in eccesso, ho dovuto modificare il condotto di raffreddamento per permettere lestrusore di prendere la temperatura corretta

> 24 hourExcellent! All parts are in the box for almost any install. They are pretty low noise at full speed, but I used the low noise adapter on the Ubiquity USG Pro 4 and they are virtually silent. The low noise adapter spins the fans slightly slower, but the temperature is holding at normal temp no problems.
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.
