Received the following alert this evening for my firewall. It corresponded to stopping of Internet access.
2026-01-22T22:51:13-06:00Noticekernel[370] nvme0: temperature above threshold
My firewall is installed in my garage in Minnesota and the outside air temperature is below -20 F degrees. Health report states the CPUTEMP is 0 Degrees C. My garage is probably below -5 right now.
The graph seems to not allow below O measurements.
Any advice besides heating my firewall with a hair dryer?
You can look at the actual NVME temps with "smartctl -a /dev/nvme0ns1" after having installed the os-smart plugin.
These things tend to get very hot, especially with high usage. You might suffer the "hostwatch" write problem discussed here (https://forum.opnsense.org/index.php?topic=50416.msg257543#msg257543).
