Ich zitiere mal:
What is TCTL?
The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. ... In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor.
Tdie is the actual temperature at the CPU Die, Tctl/Tdie is that Tdie temp with and offset added. You should check the CPU Temperature using the newest version of Ryzen master because at the moment it is the most accurate.
CCD1 steht für den CPU-Chiplet mit acht Kernen alias CCD (Compute Cache Die) .
Zur GPU:
Junction temp is the hottest point on the die
EDGE ist mMn die Temperaturgrenze und MEM die Temperatur des VRAM.
Und btw...wäre echt nett mal anzugeben, um welche Hardware es sich handelt.
