> 3 dayused this for my Rasp pi 3 that put under heavy load frequently. before it averaged 45-50C and now never really reaches 46. 10/10 recommend buying this.

> 3 dayMine came with a omnijoin adapter for a 4 pin connection. The fan has a 3 pin connection and it will not fit. Might increase my rating if noctua sends me the right part.

> 3 dayDespite wondering why I was paying $14 for a tiny fan, I dont regret this purchase. I have this installed in a custom case for a Comma.ai self-driving device in my car. It keeps the device cool and is nearly inaudible with the car running. I can also trust that this thing will outlast the Comma device itself. A cheaper fan may have accomplished one or two of these things, but it sure wouldnt be able to do all 3.

> 3 dayThis was an addition to my Pi 3, dilivery was fast. The fan fits in the case very well ans runs very quiet. It comes with rubber attachments that reduse noise.

> 3 dayThe packaging is crazy for just a fan. This fan is way more quiet then the piece of junk cheap fan that came stock in my NVR power supply and case. The thing sounded like an aircraft taking off, but changing to this noctua fan made everything normal like it should be - whisper quiet now. Super impressed with this fan and well worth the extra few bucks. any future fans I get will be Noctua.

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and an AAO standard frame, the NF-A4x10 5V is a dedicated 5V version of Noctua’s highly optimised, premium quality quiet 40x10mm fan. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and the OmniJoin Adaptor Set, the NF-A4x10 5V is a premium choice for demanding 5V applications.
5V version
Many devices such as network or storage solutions use 5 volt 40mm fans. With the same operating voltage and the included OmniJoin adaptor set that makes it compatible with proprietary fan headers, the NF-A4x10 5V is ideal for replacing noisy or broken 5V 40mm fans.
Please Note: Being a 5V fan, the NF-A4x10 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.

|---|---|---|---|
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. |
Reduced motor hub sizeThanks 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. |
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. |
Please Note:
Being a 5V fan, the NF-A4x10 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
