In recent years, the type of bearing very much, Thermal Products or several, there is no new progress. Recent radiator manufacturers in terms of bearing radiator made ??of new technologies, such as wave bearings, magnetic bearings, core bearing several basic form bearing to be improved. How it works is not changed too much.
 
The early run, low noise, low manufacturing costs, but this serious bearing wear life than ball bearings have a big gap. And this bearing use over time, due to the oil seal (computer radiator is not possible to use high-grade oil seals, the generally ordinary paper seals), oil will gradually volatile, and the dust will enter NSK Bearings, cause the fan speed slows down, the noise increases, but also serious because of bearing wear caused by the fan and eccentric lead to severe vibration.
