I think you could do that with openrgb and both the visual map plugin (same link as I posted before) and hardware sync. I haven't specifically tried it, but from what I have done, I think it's quite doable.

Use visual map to create individual control over numpad lights (as opposed to keeping them grouped up with the rest of the keyboard, which gives less options), and then in theory you should be able to map any temp reading to any key that you've separated from the group.

There's more than just temps as options too. Poking through, I saw stuff like power draw and clock speeds, ram usage/availability, and ethernet throughput. Could be fun to map stuff like that, though likely that would have less utility in most situations.
