OPNsense 25.7.10 . Noticekernel[370] nvme0: temperature above threshold

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.
