Why are my new CPU temperatures so inconsistent?

Asked by TechWhiz42
I recently upgraded to a Ryzen 5800X and applied Noctua NT-H2 thermal paste, and I'm using a Kraken X53 cooler. However, I'm noticing that the temperature readings are quite erratic, with OCCT and NZXT showing different values. Do I need to wait for the thermal paste to settle in, or should I adjust the fan settings to even out the temperatures? Thanks for any insights!

It sounds like NZXT is reading between 40-60ยฐC and OCCT shows around 30-35ยฐC when idle. As soon as I start doing anything on my PC, OCCT jumps to over 45ยฐC. It might just be how the coolers and software are reading it right now.

What temperatures are you actually getting? That's key to figuring out if thereโ€™s a real issue or not.
