I've seen from previous version and also this one that in one of my computers (AMD with also AMD GPU, this one not embebed in processor, standalone):
data from Open Hardware Monitor (OHM) both CPU & GPU, AutoStart with system startup.
TT also in startup.
started system and TT only displaying one temperature, supposed to be CPU temp, and no way of showing the GPU temp.
killed & restarted TT and now showing both temperatures correctly.
use to happen from time to time and after systems updates like windows update, etc.
I'm glad this fixed the problem, took me a while to dig in the source code and find the problem.
