Noctua NF-R8 redux-1800 PWM, High Performance Cooling Fan, 4-Pin, 1800 RPM (80mm, Grey)
80mm fans are common in 4U cases, and that’s exactly where a Noctua Redux 80mm can make a difference. I like having PWM control so I can keep airflow where it needs to be without unnecessary noise. In a NAS that runs 24/7, that balance matters.
