ComfilePi B seres (CPi-Bxxx) has a larger heatsink.

Throttling protects the device from overheating by reducing the CPU's frequency.

The Raspberry Pi goes to throttling mode over 85 degrees Celsius.

I tested using an aging test program on the CPi-Bxx model.

CPU temperature is 69.3 degrees Celsius.

I measure this using multimeter.

The temperature at the back of the device is 50.3 degrees Celsius.

The CPi-Bxxx series doesn't go to throttling mode.
