I'm surprised that nobody has reported this.

Some rigs using t-rex do not show the temperature information of the GPUs. In the capture all the rigs use t-rex at that moment, but I always have 2 that never show the temperature.

A plate is old but the rig 5 is a modern z270. But as far as I know, the temperature issue reacts on the remote aftherburner.
I read something in the T-rex forum about this same error.
