The official recommendation of the CPU manufacturer NXP for the CPU chip (MCIMX6G2CVM05AA):
If the junction temperature of the CPU chip in use exceeds 105°C, the CPU will enter the over-temperature
protection state and will not be able to start and run properly. Take thermal measures to ensure that the junction
temperature of the CPU is below 105°C so that the CPU can boot and operate properly. If the core board is used
when the ambient temperature exceeds 70°C, or the junction temperature of the CPU chip exceeds 105°C, it is
recommended that you use a temperature collector to collect the surface temperature of the CPU. If the surface
temperature of the CPU exceeds 90°C, take heat dissipation measures, such as adding radiators and fans.
To protect the CPU, takes the following measures for the factory firmware by default:
1) When the board core board attempts to start, it is not allowed to start if the CPU junction temperature
exceeds 100°C;
2) After the core board is started, if the CPU junction temperature exceeds 100°C, the system will start the
frequency reduction function to reduce the junction temperature;
3) When the core board starts, the system will automatically shut down if the CPU junction temperature
exceeds 105°C.
