The size of 5cm cooling fan is 5010, 5015 and 5020. In addition to the size, there are current, power, speed, air volume, air pressure and noise. The three sizes have the following models:
5010,DF5010B05L,DF5010B05M,DF5010B05H,DF5010B05V,DF5010B12L,DF5010B12M,DF5010B12H,DF5010B12V,DF5010B24H,DF5010B24V,DF5010B24S,
5015:DF5015B05L,DF5015B05M,DF5015B05H,DF5015B12L,DF5015B12M,DF5015B12H,DF5015B12V,DF5015B24M,DF5015B24H,DF5015B24V.
5020:DF5020B05L,DF5020B05M,DF5020B05H,DF5020B12V,DF5020B12L,DF5020B12M,DF5020B12H,DF5020B12V,DF5020B24L,DF5020B24M,DF5020B24H,DF5020B24V.
With FG, RD, PWM, PR, SS, as, ipx5 moisture-proof function, it can be applied to battery formation, lithium battery charging and discharging equipment, frequency converter, 3D printer, medical equipment, beauty equipment, stage lighting, military industry, smart home, car charger, protective clothing and other industries.
Let's compare the parameters with the highest speed of the three models:
5010, maximum speed 6800, current 0.14, power 1.73, air volume 0.43, air pressure 0.21
5015, maximum speed 6500, current 0.32, power 3.84, air volume 0.55, air pressure 0.28
5020, maximum speed 7000, current 0.18, power 2.16, air volume 0.68, air pressure 0.48

From the above comparison, the maximum air volume is 5020, and the power consumption is not so large. If the space allows, it is recommended to select 5020, which will have better heat dissipation effect.
