TCTL/TDIE vs CPU CCD1 & CCD2 DIE Can someone explain to me what these mean?
Hello, I have the Ryzen 3900 (The OEM Fancy 65W Chip, not the more powerful 3900X chip).
Looking in HWiNFO64 I have 4 readings for the CPU Temperature.
CPU (TCTL/TDIE) at 47.3c
CPU DIE (Average) at 37.7C
CPU CCD1 (Tdie) at 36.5c
CPU CCD2 (Tdie) at 33.5c
I've read that the X CPU range has an offset of maybe 20c, but wasn't sure if the same is true for the OEM 3900 chip. To confuse matters more, why does it show Tctl/Tdie? and whats the difference between CCD1 and CCD2?
What temperatures should I be looking at to gauge how cool my CPU is running at?
Tctl is a fake temperature, if you compare it to CCD1/CCD2, it absolutely has no bearing on the real temperatures during idle, and it's equal to the highest of both under full and constant load. It's basically a (borked) system that was designed to predict temperature spikes and pre-start fans earlier to keep the CPU somewhat cold. What it creates in reality is a sort of 'sawblade' pattern which causes fans to spin up and spin down constantly if the default mobo settings are applied.
