Review: Good little fan and worth the extra price. Quiet and lasts forever - Bought this to replace the broken stock fan in my UGREEN NAS DXP2800 and it ended up being a perfect drop‑in upgrade. Noise level: At typical NAS fan curves it’s basically whisper quiet, even sitting on a desk a few feet away. Cooling: Despite the low noise, it moves enough air that my drive and system temps stayed the same or slightly improved compared to the original fan. Cable length: The included cable is long enough to route cleanly inside the NAS without needing an extension or weird bends. Mountability: Standard 92mm mounting holes lined right up; swap took a few minutes with just a screwdriver and no mods needed. Speed and airflow: PWM control works as expected, ramps smoothly under load, and at higher RPMs you get noticeably stronger airflow without a huge jump in noise. Overall, if you’re looking for a reliable, quiet replacement fan for a small NAS or SFF build, this one is worth paying a bit extra for.
Review: Best 92mm fan on the market - The Noctua NF-A9 PWM (92mm, 4-pin) is one of those components that quietly justifies its premium price — literally and figuratively.I've used several Noctua fans over the years, and this 92mm PWM model continues the brand's reputation for exceptional build quality and acoustic performance. At max 2000 RPM it pushes a solid amount of air (around 78.9 m³/h), yet the noise tops out at just 22.8 dB(A) — in practice, it's barely audible even in a near-silent room unless you put your ear right next to the case. With the included Low-Noise Adaptor plugged in, it becomes whisper-quiet while still providing perfectly adequate cooling for most 92mm applications.What stands out:The PWM control is smooth and responsive; the fan ramps up/down almost imperceptibly as temps change. Flow Acceleration Channels and the AAO (Advanced Acoustic Optimisation) frame genuinely reduce turbulence noise compared to generic fans. Comes with a generous accessory kit: anti-vibration mounts (the classic brown grommets), extension cable, Y-splitter for daisy-chaining two fans on one header, screws, and the LNA adaptor. Build feels rock-solid — fibre-glass reinforced PBT blades, SSO2 bearing, and Noctua's legendary >150,000-hour MTTF rating give real confidence it'll outlast most other PC parts.

### ⭐⭐⭐⭐⭐ Very good fan
*by S***Y on January 9, 2026*

This thing is amazing, and it comes with different connectors: Y-connector, an extension, and a quiet connector. This fan is quiet, doesn't rattle on the case due to its rubber padded corners, and it performs well. Very good quality fan.
