How to cool down a Hypertherm EDGE Pro Ti Control Systems CNC that feels excessively warm?

If the Hypertherm Control Systems CNC feels excessively warm, first check if the external fan is running. If it's running slowly, clean it. If the fan isn't running and the ambient temperature is above 70° F (20° C), check that the internal harness connects the fan to the Utility board. Also, remove the fan shroud and ensure the fan connections are secure. If necessary, replace the external fan (428007). If the external fan is running but the CNC remains excessively warm, open the front door and confirm the internal fan is running; if not, replace it (228474).
