[SOLVED] Ryzen 1950x CCD Temps too high ?

[Sowmitra Das Sumit]

I am running the following system,
Ryzen Threadripper 1950x
MSI MEG X399 Creation
Corsair RM750x
NZXT Kraken X73
GSkill Trident Z RGB 16 GB 3200 MHz
Zotac GTX 1080 Ti Amp Extreme

My system was running fine for 1 year, but few months back suddenly started to post 00 after running for 30 minutes to 1 hour. I was running a Thermaltake Toughpower 850W Gold PSU back then. I thought the psu was faulty, and changed it to the Corsair one above a few weeks back. But, the problem was not solved. I was also using an Enermax Liqtech TR4 II OC, and thought that the issue was due to thermal throttling because the AIO pump had failed (common issue for Enermax TR4 AIOs). So, I changed it to an NZXT Kraken X73 today. Still, the CPU CCD temps are close to 60 degrees in idle (although the package temperature is around 30 degrees - as shown in Open Hardware Monitor).
Are these temperatures normal? If not, what could be the problem... since, clearly the cooler's not an issue.

1950X Tjmax is 68C (specs from the AMD web site). That would be an expected temp only under heavy load and that does seem low to me since all Ryzen CPU's with the same architecture and process have TJmax rated at 90 or 95C.

The idle temp you're seeing is probably more due to background processes that may be running so look at that. Also, a radiator that's mounted to exhaust case air through it will run warmer at idle than one mounted to use intake air since it's using the warmed air exhausting from a GPU.

Not sure what 'Open Hardware Monitor' is but many monitoring utilities are notoriously inaccurate with Ryzen CPU's. I'd suggest using HWInfo64, it shows more complete temps since it decodes more of the sensors in the telemetry stream.

What does post code 00 cross to? It should be in your manual.
