Ryzen temperature jumps (ASRock X470 Taichi + Ryzen 7 3700X)

I noticed some strange behavior of Aida in temp measures: when my PC in idle, CPU temp jumps once on 5-6 seconds from true idle temp to temp on simple load (from 32 °C to 45 °C). This changes show on my outer display via Aida sensor panel. From the other side Ryzen master shows idle temp near 32-34, renewing timings are same on both programs. CPU load is near 1% on idle. Voltages fix on 1.36, clocks fix on 4.3 GHz, ryzen master shows that max cpu clock on idle can be near 3.7 GHz in one core, others can be near 0.8 or full idle (parked/sleep). What's problem can be?

I don't think there's any problem.  Windows 10 does a lot of funky things in the background which could wake one ore more cores up from their sleep state from time to time.

As for the temperature differences: please note that Ryzen Master calculates both thermal and clock averages in order to smooth out spikes in their readings.  While AIDA64 keeps measuring immediate readings that will indicate (and in some cases reveal) spikes.

Ok. I see. But one more thing:  when my pc on idle, temps behavior very predictable and regular, when temp become 32-35, without any load, checked it on machine with clear OS additionaly without internet connection (some processes in OS can use internet connection and use CPU for it) , they immediately bumps up to 45-47 and goes down to 32-35 again in 5-10 seconds, so it's look strange
