Stealing Noctua's quiet airflow mod - Shroud for 120mm and 140mm fans
When fan blades spin too close to a PC case panel, turbulence builds up—creating unnecessary noise and reducing cooling efficiency.
Noctua tackled this challenge head-on, engineering a precision spacer that cuts noise and boosts airflow.
Thanks to standardized fan and case dimensions, the 3D-printed spacers fit to any brand—giving every build the silence and performance it deserves.
