Pi0W reaching 140°F

Mon Oct 12, 2020 10:49 pm

Recently I bought a pi0w and when I use a basic pi0w made OS it will reach temperatures of up to 140°F on the CPU. This definitely cannot be normal and I'd like to hear if anyone else has had the same problem of severe overheating?

Thanks, Chris

That's only 60centigrade, so well within normal operating boundaries. The device will throttle if it hits 85C, which is very unlikely on a Pi0.

Pi's don't overheat, they get hot, but the firmware will ensure they don't overheat, by slowing down the CPU's.

Also use:

Code: Select all

vcgencmd get_throttled
if it returns anything other than 0x0 its likely throttled (now, or since the last boot) due to over temperature or under voltage.
As JamesH said, very unlikely on a Pi Zero.
Pi4 8GB and Pi4 4GB running Raspberry Pi OS 64-bit
