Stall Protection Note
If the fan is stalled due to foreign objects, it will automatically resume operation after the obstruction is removed. However, prolonged stalling may damage the fan or even cause it to burn out. Therefore, please promptly clear any blockages and ensure the fan operates normally.
Cooling Module Installation
The air intake of Module Fan v1.1 is located at the bottom of the module. For optimal cooling performance, it is recommended to stack it on top of the module that requires cooling, as shown in the image below.
