Hi

Processor: AMD Ryzen 5900x
Aio - Corsair 360mm H150
Case - Lian Li O11 Dynamic with 6 extra fans.

This is the first time I am using AMD ecosystem. I changed my motherboard and processor yesterday.
Coming from an intel platform I thought temperatures will be lower. My i7 9700k idle
at 29-34 higest and while gaming its 60 max. However my AMD idle temperatures are sitting at 55-60 and even when opening a browser it shoots upto 70 and sometimes 81 degrees. This doesn't seem normal.

I tried repasting 4 times using Thermal Greasly Kryonaught and Artic MX but still its same.

I have a really good push/pull configuration.

Do I have a faulty processor or am I doiny something wrong.

Please advice.
 
I've had similar results after recently upgrading to a Ryzen 5950X (MSI MEG X570 ACE motherboard, BIOS version 7C35v1D), from an i9 9900K.

When first getting into Windows after the upgrade I found my idle temps were 50-odd degrees. It was so high I didn't dare do a stress test initially, I thought I must not have got good contact with the cooler. I took it apart to check though and it was mounted properly, though the mounting mechanism for AM4 doesn't seem like it will apply as much pressure as the one for LGA1151 socket.

I did a stress test with Cinebench ready to stop it almost immediately, and found the temperature only rose to about 65c under full load on all cores! It gets higher than that if I do the single core benchmark instead!

I did a bit of tweaking for things that were using more CPU than necessary at idle, and now it idles at about 47-48c. That's with a Corsair H150i and a custom fan curve that takes both the pump and fan speed down low until the coolant gets warm - it tends to reach 35c coolant temp at idle with the profile I defined. If I put both pump and fan up to max then it drops a few degrees, coolant temp comes down to 30c and CPU cores 40-41c or so in 24c ambient temperature.

I think the issue might be with the voltage supplied and clock behaviour. I don't know if I can trust what Core Temp is showing me, but if I can then the cores are never dropping below 3.6 GHz at idle, and Power showing at about 30-32W. That's with the power profile in Windows set as "balanced" - if I switch to the "Power Saver" profile it will go down to 3.3 GHz and 28-29W at idle.

With the i9 9900K I had previously then the core temperature at idle would basically drop down to the same as the temperature of the coolant itself.

I don't think I can trust what Core Temp is showing though - I just installed AMD Ryzen Master instead and that shows significantly different information - at idle, clock speed hovering around 313-530 MHz and voltage about 1.1 volts. It also shows the temperature at about 36c while Core Temp is showing individual cores at 40-41c.

I used Ryzen Master to monitor things while experimenting with Cinebench - no overclocking applied at the moment, just using it to monitor. The single-core benchmark shows it running one core at up to 4.9 GHz and total power at up to 45% of the 142W limit, temperature reaches 65c. Multi-core benchmark goes to about 3850 MHz, total power at 86% of the 142W limit, and temperature 62c.

Voltage control in the UEFI is just set to "Auto" as standard.

So - veteran AMD owners - is this just how these processors are, or do we both have an issue here? It seems to me like maybe the voltage should be dropping lower than that at idle.
 
Yes exactly my same question - after moving from intel these temperatures are alarming. Also the problem is that I have never done any OC or under volt. So I need to research a bit. I am someone who likes to buy something and just put it on my desktop so that it works.
If the temps are still like this maybe I will return it and get Intel i9 10850K. As I just play games, stream and sometimes code.

Also should I fresh install the windows? As I did not perform any reinstallation for Windows after changing the processor and motherboard
 
I do not have any RGB fans, but my Corsair RAM is RGB and Corsair iCue software is installed to control the lights on the ram and fan speed thats it. However, I will perform a full clean installation of the windows

Just force close them from task manager? No need for a full reinstall.
 
I didn't explicitly mention in my previous post here - I'm also using a Corsair H150i Pro as my cooler, just a single row of fans though not push/pull like iwolverine.

No RGB anywhere on my setup, I even turned off the "mystic light" thing on the motherboard.

Checking using task manager and sorting by CPU use at idle, after I first upgraded I found MSI Afterburner was using 2-3% CPU at idle, and when I checked it all the additional CPU cores were being monitored and graphed for frequency, power use etc... so I turned all that off.

I also un-installed the Mystic Light software entirely since that was using a couple of % at idle (not even running, it seems to have some pointless background process just by having it installed), fortunately if you use it to turn off the lights then un-install it they stay off.

Now at idle I just get the "System Idle Process" at 99%, no other processes reach even 1% use. Temperature at idle is still bad though, 48-49c right now as I type this.
 
From what i have been reading and informed it seems to be very normal temps for idle & load, the only way i found to keep them under check for now is ECO mode. Without ECO mode hitting high 70's or 80's browsing/gaming right now is not to much of an issue but once the warm weather comes it will be nuclear
