Mellow 3D Printer fan 12V/24V 40*10mm 4010 Dual Bearing Blow Radial Extruder DC Cooling Turbo Fan Turbo Fan for CR10 Ender 3

The double-ball bearing fan is the best, it can be used continuously for 24 hours without maintenance, and the sound of the ball may be heard at the beginning, and the sound will become smaller and smaller as time goes by.

The most common ones are bearing fans. It is recommended that the continuous use time be less than 10 hours, because the internal lubricant will dry up. If it is dry, lubricant can be added. The disadvantage is that the service life is short and the use time is less than 1 year. The advantage is very cheap.
