My Raspberry Pi 3B Plus is running Raspberry Pi OS (32-bit) Lite. I only made
upgrade and install
It is connected to my home network with 1Gb Ethernet cable (no WiFi). Network traffic to the RPi is virtually 0 Mbps.
There is no heatsink installed.
htop is the following:
Which looks like it's almost free of any task.
However it is pretty hot. I can barely hold my finger on SoC and network chips. My thermal imager shows this:
(Note that the dark squares on the top image are reflective surfaces - which always looks dark on thermal images)
Highest temperature is 51°C with ambient 28°C.
I dont't have anything to measure current consumption, but I'd say that it is far more than normal. I remember that in idle my RPi 3B Plus was just warm a little bit.
- What can I do to debug this situation?
- What can I do to decrease power consumption?
- What else besides SoC can contribute to the power consumption?
