CPU temperature warning

Using the Pioreactor
1

Dear friends!

I am using a Pio-cluster (being the leader a RBPI5).

I keep getting the warning message from monitor of:

“CPU temperature at 79 ℃”

Any idea of what this could be?

Thanks in advance!

That’s pretty warm for a Raspberry Pi, but also expected! RPi5s do consume a lot more power than other versions. A hot RPi (above 80C) will throttle itself, so you might be losing some performance. A few ways things you might consider changing:

  • adding metal heat sinks to the Pi’s chips. These aren’t very effective, but have some difference.
  • Allow more air flow by moving objects clear of the Pi. This isn’t always possible in the Pioreactor.
  • Cool the ambient temperature more.
  • Ignore it. If it reaches 90C+, then I would worry more.
