Stall Instructions
If the fan stalls due to foreign objects, the fan will automatically resume operation once the obstruction is cleared. However, prolonged stalling may damage the fan and even cause it to burn out. Please promptly clear any blockages and ensure the fan operates normally.
Cooling Module Installation
The intake of Module Fan v1.1 is designed at the bottom of the module. To achieve effective cooling, it is recommended to stack it on top of the module that requires cooling, as shown in the image below.
