Before, I shared with you what a turbine is.Pressurized cooling fan, Let's introduce the difference between turbocharged cooling fans and ordinary cooling fans.
First: the turbofan can output a larger air volume in a smaller space occupation and improve the heat dissipation effect.
Second: the machining accuracy of the fan blades of the turbo fan is higher than that of the ordinary cooling fan, and the noise emitted by the impeller is also greater when there is dust accumulation or high-speed operation.
Third: now with the decline in CPU power consumption, the CPU turbo fan is gradually replaced by a large-diameter low-speed ordinary axial-flow silent fan, but it is still often used on high-performance graphics cards, especially public graphics radiators.

Fourth: The turbofan is driven by a motor to rotate the impeller. The blades in the impeller force the gas to rotate and do work on the gas to increase its momentum. The gas is thrown out around the impeller under the action of centrifugal force, and the kinetic energy is converted through the vortex casing. For pressure energy, when the gas in the impeller is discharged, the pressure in the impeller is lower than the pressure in the air inlet pipe, and the new gas is sucked into the impeller under the pressure difference, the gas is continuously discharged from the fan.
