This cooling fan is specially built for Raspberry Pi 4B / 3B +. The heat sink and fan are integrated, heat conduction + heat dissipation, and the function is more significant and efficient.
The fan blade adopts NACA airfoil design, optimizing air flow, reducing noise, more wind, and better heat dissipation performance.
Aluminum alloy heat sink, heat conduction faster.
The back is equipped with thermal conductive glue, which can be directly pasted by tearing off the adhesive paper, which is easy to install.
Equipped with an upgraded heat sink package, which has significant heat dissipation function and can be used with different Raspberry Pi Board.
