Brand new ball bearing miniature cooling fan 4028, the fan is very convenient to use, if you just want to run it simply, then connect the red wire to the positive pole and the black wire to the negative pole (other second wires are suspended without wiring), and the fan can be at the highest speed It runs, if precise control is required, it can also be adjusted with PWM speed. (The blue wire is connected to the PWM signal wire)



Fan size: 40*40*27.9MM

Wire length: 300MM

Weight: 49g


Red line: DC12V positive

Black wire: DC12V negative

Blue wire: PWM (above 500HZ), the negative pole of PWM should be connected to the black wire in parallel

Yellow line: It is estimated that it is a feedback signal line, which is left unconnected.

There are two wiring methods for this fan:

1. Connect the positive pole of the power supply to the red wire and the negative pole to the black wire, and the fan will operate normally. At this time, adjusting the voltage can also adjust the fan speed.

2. The positive pole of the power supply is connected to the red wire, the negative pole is connected to the black wire, the blue wire is connected to the PWM (pulse above 500HZ), and the negative pole of the PWM is also connected to the black wire. Adjusting the duty cycle in this way is a high speed. (20%-99%)

---------------------------------------------
The following measured fan speed at different duty cycles:
