New Ryzen 3600 high idle temps and won't downclock

[Cs342]

So I just built a new PC with a Ryzen 3600 and Hyper 212 Black Edition RGB. I'm checking CoreTemp and the CPU  idles at 50C which is very high. My old CPU would idle in the low 30s. I also noticed that the core frequency stays at 4,050 MHz instead of downclocking when the system is idling. My old PC would run at lower clocks when I was idling at the desktop. I'm worried about these high idle temps since the Hyper 212 should be able to keep the CPU reasonably cool. Is it a thermal paste issue and should I reinstall the cooler, or is there a software solution? (Also my RAM is running at 2,133Mhz instead of 3,200Mhz because I haven't set it up in the BIOS yet)

i would check thermal paste, resit everything carefully. with my old i5 2500k i didnt sit the fan properly and idle temp was 10C above mb temp, didnt even realize for years it was running at 99C lol. wats the usage at idle? i think usage is alot more important than clock for temp.

Sit the fan? Do you mean the fan wasn't properly attached to the CPU cooler?

the whole thing wasnt clipped on to the mb properly. can u check usage %?

yes, or if its very fresh build simply recheck the screws make sure you secured it reasonably well.  Make sure to use the "twist" method if/when you do take cooler off as if the thermal paste is tacky it can sometimes rip it out of the socket and take some pins, shouldn't be a problem with better quality thermal paste but still good habit to get into

Before that check voltages at idle, should be around or below 1v in Ryzen Master, jumping to about 1.35-1.4 under load.  Check with Ryzen Master, don't check with HWInfo64, HWInfo64 pings the hell out of the CPU in a way it presume HWInfo64 is a actual workload and raises temps accordingly.  CPU-Z is also acceptable way to check.

With a decent tower cooler you should be able to idle (absolutely no load) around 30c

Likely if its not the cooler its BIOS revision paired with bad settings

Flash your BIOS to the newest rev. after you check to make sure your HSF is mounted properly. This should solve the boost frequency issue.

^That might be a extreme way to go but if it is firmware related the most likely fix

If you aren't willing to update BIOS atleast look for these settings and make sure they are set as so

It was recently confirmed by AMDRob that most issues with Ryzen 3000 voltage issues, usually resulting in issues with excessive power consumption at idle, were due to occasional mobas not being setup correctly and he cited the 1usmus guide as exactly the way they should be set. he talked about it somewhere about 40 minutes into this 

Link to article with more information about bios settings: https://www.techpowerup.com/review/1usmus-custom-power-plan-for-ryzen-3000-zen-2-processors/ 
I'm not recommending you download this power plan, but atleast check if BIOS is set correctly, where it applies and download most recent official chipset driver if you haven't already.

Updating the BIOS is a very routine and fundamental step when building a new system. There's nothing 'extreme' about it.

don't disagree and its best way to solve it, just stated incase for whatever reason (constant power outages in his area, no quick warranty if he bricks it etc) they weren't willing to.

Fair enough, but a UPS is your computers very best friend.

What are you using to monitor temp?

The latest BIOS for my motherboard (MSI Tomahawk Max) is a beta BIOS, is that safe to flash?

I wouldn't trust a BIOS rev. in beta.

What's your V core voltage while idling OP?
