A TechTuber has constructed a bulbous 15x fan PC case side panel as a cooling experiment. If you think the mind-boggling design of the ‘Superdome’ is familiar, that’s probably because the fevered imagination of Major Hardware was also behind the custom domed 15x fans in the ‘Fanhattan Project’ we wrote about last month. How well does it scale to PC side panel use? Let’s see.
Building the Superdome: A 15-Fan PC Side Panel - YouTube
The freebie Noctua fans arrived before the TechTuber had drafted the Superdome in 3D, but the idea was made to work with five fans around one on top of the dome, and nine surrounding them at the base of the dome, near the PC. Cabling routing was yet to be decided.
Next, we see Major Hardware 3D print the structure of the Superdome, and luckily, the Bambu Labs H2D and H2S build volume was just enough to prevent more design splitting than would be ideal. Still, it took days to output all the pieces.
The finished work looks great from the outside, but Major Hardware is the first to admit cable management is “a little bit of a disaster.” But it was “honestly pretty quiet,” as long as none of the cables swung into the fan blades. All the fans were configured to be intakes, so we guess that when attached to the PC, the build would have a soupçon of positive internal pressure.

Battlefield 6 gaming thermals test
The proof of any success from equipping the Superdome would come from an A/B Battlefield 6 gaming challenge, decided the TechTuber. With the standard glass panel equipped, he observed a top temperature of ~86°C in the Ryzen Master software. Swapping to the Superdome and playing a few more BF6 games, and Major Hardware saw that the CPU temps had dropped to approximately 67°C. “I dropped about 20°C just by putting the Superdome on the front of my PC,” noted the TechTuber. “This is pretty incredible, and it's not even loud.” However, sitting beside the PC, he felt “a constant breeze.”
Major Hardware has decided to share the 3D printing files on Thingiverse, so others with a Lian Li O11 case and a few spare fans can easily follow in his footsteps.
