this worked for me

dozens of threads on this forum of people complaining the same thing here's an example Ultimately, until you've experienced it I dont expect you to understand. But being the end user, there is definately something not okay about this, for starters having the cpu get a CONSTANT 1.4v is NOT right

it's definitely an issue

youtubes still processing the video.

So, this is an issue I've seen people discussing, all over the place. I've spent HOURS and HOURS looking for solutions, I've tried moding the fan curves, I've tried disabling PBO, I've tried powered balance and god knows what else. BUT today, I've found a solution. so first and foremost, I'm running a Ryzen 3900x on the MSI MEG Ace motherboard, and the problem that I had was, that my CPU temps would ramp up +10°C every couple of seconds and then climb back down almost as quickly before it would ramp back up and so on and so fourth. I finally realized that my core voltage was consistently at ~1.4v and would not drop below like ~1.3v. I spent hours looking at solutions from, changing ram speeds to, updating bios to changing power plans and moding fan curves, disabeling monitoring software etc... However, I have finally found a solution that works for me, and I hope it will work for you too! first let me say, I download AMD Ryzen master and as soon as I started it, it did seem to have an impact on flattening the curve, but it really didnt solve my problem. the solution was simple for me, I went into my power plan advanced settings [I have it set to AMD High Performance] [I obviously tried other settings, power save did solve the problem, but limited my computers performance] Power Plan> Advanced settings> Processor power management> Maximum processor state> and changed it to 99% BOOM, Solved immediately, my CPU core voltage dropped instantaneously and the CPU temp spikes stopped the second I clicked apply. Hope you find this useful, best of luck -Shastin

just curious, did that ever work for you?

I've solved a problem that has been plaguing me! My Ryzen 3900x x570 MSI MEG ACE would temp spike constantly +10c every couple seconds, fans would kick in and drop the temp after a few seconds and wham +10c again. AND AFTER playing around for hours I got lucky and got it to stop. First thing to know, I didnt play with anything in the Bios except the fan curves and installing ryzen master did seem to flatten the temp spikes a bit but was not the solution. 2nd, I noticed through Ryzen master that my CPU voltage was ALWAYS 1.39 or ~1.4, after solution below, average core voltage dropped to ~1v my CPUs temp would idle anywhere between 38c to 48c, or 48c to 58c depending on my power plan. but the temps would not stop spiking no matter what i did unless I put it in low power state. anyway, solution was to change my power plans Max processor state to 99% instead of 100% and wham, instant solution. fan's stopped ramping up, CPU's idle temp is consistantly 40c now using the AMD Ryzen High Performance power plan hope this helps someone out there

I was having the same problem, you can turn it on in bios by changing the fan speed Go to fan settings, chipset and on the left hand side where it says select mode, choose manual. Then define your own fan curve by moving the blue dots
