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: Very good fan - 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.
