Airflow enthusiast 3D-prints 15 tiny fans to fit inside a custom, domed Noctua NF-A12x25 frame — bizarre 'Fanhattan Project' cools the CPU just as well as a regular fan

A YouTuber, Major Hardware, embarked on a unique project called the 'Fanhattan Project,' where he 3D-printed 15 miniature fans to fit inside a custom domed frame resembling Noctua's NF-A12x25 fan. Despite its unconventional appearance, the contraption was designed to cool a CPU as effectively as a regular fan. The project involved using 7500 RPM 4.5V DC motors to power the small 30mm fans, which were arranged to match the area of a 120mm fan. The final product, resembling an atomic bomb, successfully maintained airflow and demonstrated comparable cooling performance to a traditional fan, albeit with significantly more noise.
