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 Low-Noise Adaptors, the NF-A6x25 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. Reduced motor hub size Thanks to its streamlined, compact motor design, the NF-A6x25's motor hub is smaller than with conventional 6cm fans. This allows for more blade surface area and thus contributes to the NF-A6x25's superior airflow and pressure performance. SSO2 bearing The NF-A6x25 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. Flow Acceleration Channels The NF-A6x25 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.

I have a third fan on the inlet opening of the amp to help with its cooling again using only two of the wires. **Q: It looks like it has 3 wires coming out of the fan. which wires do you connect to 12 vdc, +/- , high or low speed?** A: As the last person answered, you can just connect the red and black for max speed and noise or use the provided cables to change it to the speed and noise level you like. I have two of these, one I have running at full speed and the other I used a resistance cable to slow it down to the medium speed to be very quiet and still do a good job of cooling. This is a good quiet fan and with the cables provided you have a 3 speeds, so the choice is yours. I did not use the third wire for anything. **Q: What is the current draw?** A: This is the current draw listed on the package. The Product shipped to me does not conform to this rating and only draws 0.06 amps at 12.0 volts. **Q: am i able to solder this to be powered by a batter?** A: You can cut the plug off and solder the + & - to whatever source or solder leads to your battery and plug them into the original fan plug,but remember this is a 12 volt fan by design....Hope this helps ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***E on September 8, 2025* ### ⭐⭐⭐⭐⭐ Review *by K***Y on March 29, 2023* ### ⭐⭐⭐⭐⭐ Review *by F***O on January 18, 2026* ## Frequently Bought Together - Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown) - Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown) - Noctua NF-A4x20 FLX Computer Case Fan - Cooling Components (Computer Case, Fan, 4 cm, 3700 RPM, 5000 RPM, 4400 RPM) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/3392307-nf-a6x25-flx](https://www.desertcart.be/products/3392307-nf-a6x25-flx) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-16*
