Heatsink Fan Kit for Raspberry Pi, Cooler Fan Heatsink Set with PWM Speed Control Fan for Cooling Raspberry Pi 4, Pi 3 B+, Pi 3 B, Pi 2, Pi B+, Pi Zero/Zero W and Jetson Nano, RockPi

The version with three wires is a fan that supports PWM signal speed regulation, and other fans are suitable for cooling different SBCs, even for 3D printer's heat dissipation.
NOTE: For two-wired fans, the red pin is 5V IN, and the black is GND. This type of fan only supports voltage input between 3.3V and 5V. For three-wired fans, in addition to the red and black pins, the blue pin can accept a PWM signal to control the fan speed.

This is a radiator and fan set, complete fan types, suitable for Raspberry Pi and Jetson Nano series products for cooling use.
Different materials of radiators are suitable for different occasions, with copper radiators, aluminum radiators, etc., and the fan also has different specifications.
The version with three wires is a fan that supports PWM signal speed regulation, and other fans are suitable for cooling different SBCs, even for 3D printer's heat dissipation.
