Okay, I will try that thanks. Dumb question probably, but what causes the core speeds to change rapidly at idle?

Thanks for the reply, In my case, my past experience with this cooler is that is drops idle temps down to 29 to 33 ish .. I think there are other things going on as well that are above my pay grade ;) in Ryzen master for example, the EDC (cpu) is in the red, around 96 percent but is fluctuating up and down. At any rate, I will keep researching and see AMD has support info.

I have had my current build for a couple of years, and used the AMD stock cooler with the intent to add a liquid cooler when I got time and funds. I just installed the H100i on my PC to get temps down. Temps were running at idle of about 44 to 50 C I have the AMD ryzen 7 2700x with the stock cooler. All stock nothing overclocked. Since the install of the cooler did not change the temps at all I am baffled as to where to start to trouble shoot. While the temps are not bad per say they should have dropped some. The ryzen master program, speccy and the iCUE all show similar temps. During install of the cooler, I did have a little trouble getting the screw clips on the pump on, meaning it was hard to do and wiggled a bit until I got it settled. Not sure if that is a factor or ??
