Modern desktop PCs cannot afford to be fanless. Of course, this is possible if the TDP of the CPU is low enough, but desktop PCs generally require some airflow. So how about this: instead of using a rotating fan to move air around inside the PC, let the PC itself rotate," is exactly what Sodabaka did on the Bilibili channel (via Tom's Hardware).

Sodabaka first tested an old Sandy Bridge-era i5 2500K Mini-ITX system and an atypical tower heatsink. They placed it in a centrifuge and spun the entire PC. The exact speed was not known, but it appeared to be about 3 revolutions per second.

The PC requires wires to be connected to provide power and display output, but Sode Baca got around this by cleverly rigging some wires so that they would not twist after half a revolution.

The PC eventually got a little too hot for comfort, reaching the 100-degree Celsius range and leading to throttling. In other words, it is not a good cooling solution for a PC. But this was not what I expected! Sodabaka tried equipping the cooler with the larger Noctua NH-P1 passive cooler, both with and without a small fan attached to the top of the cooler. However, it still recorded 100 degrees.

Sodabaka then got really creative by 3D printing larger fan blades to mount on the motherboard tray; the system with the Noctua cooler installed sped up the RPMs; the fan blades were also a bit more expensive than those with the Noctua cooler installed. However, the presence of a full-face mask and riot shields gave us all the information we needed to know that this was not a cooling option that could be seriously considered.

In the end, centrifugal force prevailed; the NH-P1 weighed over a kilogram, effectively destroying the PC in the end.

This is all in good fun and really shouldn't be taken as effective cooling advice; Sodabaka's video goes above and beyond to prove that the humble fan isn't going anywhere. Moreover, the user doesn't even have to hide behind a riot shield to operate.
