In this experiment I tried something completely ridiculous: replacing a standard 120mm PC fan with 15 miniature fans. Each tiny fan uses a scaled-down version of the famous Noctua NF-A12x25 blade design, shrunk to about 30mm, and packed together inside a custom fan frame.
To make it work I designed a dome intake with 15 individual ducts, each feeding its own fan and motor. The result? A fan that looks less like a PC cooler and more like a strange science experiment… or something straight out of the Trinity nuclear test.
But does it actually work?
To find out, we run the multi-fan monstrosity through the same airflow and smoke tests used in the Fan Showdown series to see how this wild design compares to a traditional single-fan setup.
