Thermal Raspberry Pi 3 showed a temperature of 101ºC

Thermogram Raspberry Pi 3 Model B

Bad news for those who are going to buy a new Raspberry Pi 3 .

Gareth Halfacree , author of the Raspberry Pi user manual The User Guide has published thermograms for various Raspberry Pi models , including the new Raspberry Pi 3 Model B on the BCM2837 SoC.

It turned out that the Raspberry Pi 3 Model B with a 100% CPU load (without using the GPU) warms up to 101.3ºC for five minutes!

At such temperatures, mini-computers are unlikely to be able to work normally in a case without active cooling. Well, at least the holes for ventilation must be left in the case.

The temperature of the “raspberry” rises with each version.

Gareth Khafakri checked and confirmed the result using a contact probe with a thermocouple type K.

Although the system on the BCM2837 chip is operational and tested up to 125ºC, long-term operation at 100ºC is not provided for in the specifications. The official temperature limit is 85ºC, so the Raspberry Pi should reduce chip performance at about 82ºC.

All this is bad news. It is necessary to put a radiator on a microchip without fail, otherwise there is a chance to see a trickle of smoke.

However, it is too early to panic. Perhaps Gareth caught some defective copy. He says that he contacted the Raspberry Pi Foundation, and in their benchmarks the temperature did not rise above 83ºC. Although this is also a lot, agree.
