Question Ryzen 5700x core5 temperature much higher (need help) ?

[BunnyKraken]

Hi,
If someone could help my build and my OCD to ease if this is normal or if there is something wrong. What tests should I do and how would you proceed?
My setup: Ryzen 5700x, RTX 3080, Noctua NH-D15s with 2 fans, Lian Li 216 with 2 additional 140mm Arctic Bionix F140 top fans as exhaust. The GPU is running quite hot in the case and the noctua heatsink above it gets some additional heat.

So I don't know if my overall CPU temperatures are normal and why is the core5 temperatures/peaks much higher than the rest of the cores. Could this be because of bad thermal apply, or is this just normal behaviour. Secondly if the temperatures for the core5 is still under 75C peaks and the average is around 60C does it matter for the health of the CPU and overall performance while gaming etc.
Could the CPU wear out badly because the one core is working hotter and wears out unevenly or something ?
Just want to know should I be worried about that core working harder or running more hot. I noticed that even when in desktop and opening webrowser or a folder, it is around 42-44 and then drops to 36-40 then gets back to 42c. While other cores are in 33-38 range all the time.

The peak voltage in real time for core5 (and core 1) is at 4.650 Mhz, while its 3.600-3.720Mhz more evenly for other cores if this matters ? Most workload peak is in desktop for core1 and core5. But core1 still stays cooler than core5.

Every Ryzen CPU has something called a "preferred core". This is the core that is meant to be prioritized with work because it's the one that can boost the hardest. It just so happens for your processor, Core 5 is the preferred core. You can verify this via Ryzen Master and see which core has a gold star.

Also what you're observing with the temperature fluctuations is normal. Windows has idle tasks that need servicing, it'll shove them on one or two cores because there's actually not much work, but it'll also cause the CPU to boost those cores hard, which raises their temperature.

Thank you so much for your time to help me, what a relief to hear. I will accept that this is normal behavior and not re-apply thermal paste or monitor the temperatures longer for individual cores. Thank you again, and have a very nice week

I have the same cpu and as hotaru.hino mentioned, yup, totally normal.

That and other Ryzen 5000 are meant to run normally up to 90c so you are way lower than that,
