Description
I figured it was worth mentioning, it seems the Ubuntu 26.04 default dashboard when you login shows temp, and having no where else to find it it gets it from the nvme driver.

Research direction
Start by reproducing the Ubuntu 26.04 dashboard output and inspect the NVMe temperature at /sys/devices/pci0000:00/0000:00:10.0/nvme/nvme0/hwmon0/temp1_input. Trace how the NVMe driver exposes this value; done means the dashboard no longer receives -273.1 C as the sensor reading.
