Since I got my CPU I've had these spikes up and down while idling in Windows which normally aren't noticeable and I've set my CPU fan curve to not react on them. Still, this bugs me and I'm wondering if it normal behavior or if it will ever get fixed. Some say it's a background process in Windows doing it, others say it's boost behavior. Sure, it can be mitigated by setting Maximum Processor State to 99% in the power plan but that also prevents the CPU from boosting altogether. It's been a while now since Zen2 was released so I was wondering if there is any new info.
