High temperature in system health report.

RouterOS General
1

Hello,
I have PowerBox Pro, when I check system health in winbox.
It shows voltage: 48.1 V and temperature 77 C.(cpu 3%)
77 C seems to be too high for idle operation.
Is this normal?

Same here, 49,6V 72°C
PoE Out to an HF-Link is 7W
Is this high temperature normal?
