Objective cooling fan performance benchmark with challenging geometry
Four graduated arcs test directional airflow from multiple angles
Elevated design with wide bridge reveals fan cooling effectiveness
Central spire and varied tilts expose single-direction fan limitations
Version 2b final design optimized for reliable comparative testing

This cooling fan torture test is a specialized 3D printer accessory designed to objectively evaluate cooling fan performance. Print this part back-to-back across different fans or setups to clearly see which ones excel and which fall short under demanding conditions.

The design features four gradually tilted arcs ranging from vertical to 80 degrees, positioned in all directions to reveal whether your fan suffers from single-direction airflow limitations. An elevated main body creates a wide, difficult bridge that exposes inadequate cooling, while a central spire further challenges print quality in critical areas.

Based on proven testing methodology, this benchmark part helps identify cooling deficiencies that standard prints might hide. Version 2b is the final, recommended iteration for consistent and reliable results.
