Ive used hwmonitor, hwinfo64, and ryzen master and im seeing the same temperature spikes with no indication of more load on the cpu nor an increase in voltage to the cpu corresponding to the spikes.
My room in a little hotter than usual but that should only affect the range of the spikes, also im using the id-cooling-234 with an additional 120mm noctua chromax black fan and thermal grizzly kryonaut thermal paste
