Question Ryzen 2600x cooling question

[SkyRock1986]

Is it normal for the temps on a Ryzen 2600x to hop around alot? Like from 32, 36, 38, 45, back to 32, 37, back to 45, 32, 38, 41, etc... Its like the temps are staying within a reasonable temperature, but why are they kicking around so much?

These are idle to "light browsing" temps by the way

Perfectly normal.

Just reacting to load and voltages at the time and temperature is shown as highest single core temperature and that's why it reacts fast. Modern CPUs have temperature sensors right inside the cores while older ones had a sensor in other place and some even outside of CPU package, bellow socket so temperature measurements were pretty "lazy".

Ok makes sense, I went from a i5 4690k and it didnt seem to hop as much as my Ryzen is now. My full load temps are so much better now with my Ryzen though like only 65 degrees maybe 68. My i5 got alot warmer than that. I was just worried because I never had a CPU that just randomly changed temp constantly like that

My older processors didn't jump as much either but as I said it's because of sensor placement and implementation. Ryzen has introduced XFR https://www.custompcreview.com/wiki/xfr/ to dynamically adjust frequency and load on every core and temperature is one of things that influence boost. For it to happen fast, it needs fast and accurate temperature reading and that's why it looks jumpy. Changes are actually even faster than what you can see in applications as they have slower polling intervals than what is actually happening.
In programs like HW Info https://www.hwinfo.com/download/ you can adjust polling interval to see even more changes but Average temperature is what is most accurate as but should also pay most attention to maximums.
