This looks suspiciously like unsigned int rollover.

Well its working so well that it dosen't just cool your CPU it also cools your entire computer so well that your GPU is at 0°C (32°F).

I think the air star's becoming hot again.

Actually the limit on rotational velocity would be defined by the fan radius. Eg, if the fan diameter is larger than 1m, the tip of the blade will be going faster than 5.7% the speed of light.

A fan diameter of 7.6cm. Nice.

Incorrectly?

rot_speed = 4294967296 rpm

c = 299792458 m/s

prop_speed_of_light = 0.057

tip_speed_actual = c * prop_speed_of_light

radius = tip_speed_actual / (rot_speed)(60 sec/1 min)(2π)

radius ≈ 11 µm
