Users receive the %SYS-3-SUP_THERMALWARNING: WARNING: CPU [dec] overlapped WARNING temperature error message

Core issue

This message indicates that the CPU is near the operating temperature threshold limit. [dec] is the CPU number.


Make sure there is adequate cooling in the chassis and that the chassis vents are clear. Also check if the fan tray is working properly.
