This adapters ware designed for Noctua fans in according to the measurements from the actual fans & their model(s). This bundle is 25% & will get you 4 design models in STL for multi-material 3D print. Here is a list of adapters you get in this bundle:

• 80x80 to 120x120 central mount
• 80x80 to 120x120 side mount
• 92x92 to 120x120 side mount

• the expansion slots, which include all the air inlet & outlet from A12 120x120 fan(s):
• reduced noise from swirling air from inlet / outlet curved edges for smoother transition
• better stiffness
• & less air swirling designed by a mechanical engineer, in accordance with all best engineering practices.

Suggested higher temperature resistant 3D printing material advised: ABS, ASA, HIPS, PP, PC or Nylon.

Model is tested & suited on side of 120x120 Noctua A12 fan with: M4x40 screws, nut DIN 967 M4 with washer DIN 125 (tightening parts not included)! Using other tightening sizes at your own risk to fit with part, except NA-SAV3 rubber mounts.
