Raspberry developers claim that most users of the Raspberry Pi 3 Model will never see the temperature at 100C shown by recent tests by

. Geektimes recently published information that the Raspberry Pi 3 thermal survey showed heating to 101.3ºC (without using a GPU). Based on the data obtained, the author of this test concluded that the Raspberry Pi 3 is not at all as good as is commonly believed. The Web is still actively discussing this situation.
Iben Upton, one of the developers of the mini-PC, joined the discussion. He claims that during normal operation with the Raspberry Pi 3 there will be no overheating. Upton says that the test used in the thermal survey is synthetic, in fact, the "raspberry" will not behave in this way in normal operation. “In normal work, I would say that never,” Iben Upton commented on the situation.
In the test, the processor was almost 100% loaded by running a test for calculating prime numbers. In normal operation of a mini PC, such loads are simply impossible, and the temperature will never rise to the limit fixed during the specified test. As for the temperature increase in the test, this phenomenon is due to the fact that the Raspberry Pi 3 has a 10 times more efficient processor than the Raspberry Pi 1.
When the load is poor, the mini PC processor operates at a frequency of 600 MHz. During periods of heavy load on the processor, the frequency increases to 1.2 GHz. If you make the processor work with such a load for a long time, the system starts to heat up. But when the temperature reaches 80C, the Pi 3 processor will begin to "slow down", the frequency of operation will decrease, and the heat will begin to dissipate. If the temperature rises to 85C, the processor will reduce the operating frequency to 600 MHz.
It is worth recalling that the Raspberry Pi 3 works with a 64-bit processor with the ARM Cortex A53 architecture, while the Pi 2 has a 32-bit processor. The core of the Pi 2 is the ARM Cortex A7 processor. The new processor is also quad-core, like the second "raspberry", but it is faster. As already mentioned, its peak frequency is 1.2 GHz, which is 300 MHz more than the Pi 2.
