Description
Meant to be used for offsetting 120mm PC fans from the radiators or case meshes to reduce noise and deadzone behind the hub motor. 25mm and 40mm spacers come with integrated supports that can be pried away with a flat screwdriver or something similar.
5mm and 15mm spacers can be used with either longer screws or with fans that have thin frames at the mounting holes so the hardware can be installed “internally”. 25mm and 40mm can be used either way as these have enough room between mounting points to install shorter screws and get possibly a cleaner look or more modular install.
Inspired by: Stealing Noctua's quiet airflow mod
UPDATE ON 23.10.2025 - Added 7mm and 10mm spacers.
