sanity check my temps on Ryzen 2700x

Built a Ryzen 2700x system. Stock cooler, no manual cpu overclock. Ram is @1466 14-14-14-14-30 1.4v

I'm not really sure what to expect for temps exactly. I've googled around but can't seem to find anything conclusive.
When I run prime95 high heat test, I get in the low 90's in the AMD Master app and shows I'm getting about 3.85 across all cores. Also, it's typical for when it's running odd jobs to be in the 60's. Are these temps normal? Also, I'm sure I've left out info so let me know what else I can fill in. Just asking for a bit of a sanity check.
 
It would depend on which temperatures you are reading. The Ryzens have 2 temperatures to consider: Tctl (Temperature Control) and Tdie (Temperature of the Die). For the 2700X the difference between them is 20c with the Tdie being the lower.
I would say that Tctl is the one you want to watch and yes, it will be a scarier number than you might be expecting. That said it is the most accurate thermometer because it is telling you the internal temperatures you CPU core is experiencing.

I would recommend not letting the Tctl exceed 95c (75c Tdie) with a stock cooler. In short I wouldn't go overclocking that chip very much with a stock cooler :)

Thanks for chiming in here with some sanity for me.

I thought Tdie was the internal temp and that Tctl was the adjusted temp? I know Tctl is higher though for sure so I made the fan speed adjustments based on that instead of Tdie. Idling around it actually drops into the 50s. I'm curious what folks using the stock cooler get for max top CPU speed across all cores with prime95 running too.
 
Hmm, looking over the AMD docs I see Tctl as the 'control' temperature used for fan control policies which has my statements a lil bit um ... backwards :) Tctl is calculated from the T-junction (Tj aka Tdie aka internal) Tctl = TJ/Tdie + 20 for the 1700x (I am assuming the same for the 2700X since that seems to be the same numbers you had seen) .
So that would make TJ = Tdie. Their docs still tell you to use Tctl for fan calibrating. Here's a linky if you are interested : https://community.amd.com/community/gaming/blog/2017/03/13/amd-ryzen-community-update

Sorry for confusing things.

Tctl is 10C higher than Tdie on the 2700x.
Ryzen Master shows Tdie.

Your temps seem about 10C too high for the stock cooler to me. I think you should be able to idle in the 30's to low 40's.

My system is idling at 34C in a room that is 28C (82F). When it is completely idle, the voltage is 0.8375V.
Edit: To be clear, I am not using the stock cooler. See sig for specs.
 
2700x has a 10c offset like Azrak said and Tdie is the one to keep your eye on.

With ambient temps in the high 70s(f) the stock cooler and a low level performance mode enabled that raises temps some I'm seeing idle temps in the mid 30s(c) to low 40s and 75-80c with prime(depending on the test).

If your case has decent airflow and you're not running it in a super hot environment those temps seem high and it sounds like it downclocking some because of it. I would try reseating the cooler with fresh paste if I was seeing those temps.

Also I assume that 1466 Mhz for the ram was a typo and you meant 3466 or 2933(monitoring utilities generally report mem speed at half of effective speed) because otherwise it's going to hurt performance.

There is very good airflow and the room temp is not very high (half-basement) and after a couple comments here I agree about re-seating the HS. You're right, I meant 3466! It actually performs better on 14-14-14-14-30 @3466 than at 16-16-16-16-36 @3600
 
Thanks to your thread I just learned a few things about Ryzen I didn't know. Just finished my build and had a few shutdowns at 63c... Only when running prime95, now going to look for this other temp sensor.
 
try HWINFO https://www.hwinfo.com/download.php (it's freeware and really handy)
It puts both sensors right there in the sensors view. You can even set it up to show them in your tray as well like this (that's my Tdie and Tctl - the blue icon pops up the whole sensors view):

What kind of clocks should I typically be seeing then if my heatsink is seated properly? I know this will depend on ambient temps too, but I'd be interested in what you folks have found with your systems in this regard as well. Thanks again for everything so far.

Pretty sure that is covered in the hardocp reviews. Have you read them?
 
I did go back to the review again and got good info. For some reason I missed the temps for the air cooler. Looks like mine were just a tad high. Went in and cleaned and replaced the TIM with AS5 and I'm back on track.
 
Im running the stock air cooler and typically Im about 30c at idle, low 50's with a game like Far Cry 5, and Prime 95 was around low 70's after a couple passes. My ambient temp in the house is about 68F.

So then my temps are still way too high. Need to dig around. Do you guys use RyzenMaster and PBO/XFR? I wonder if my voltages are too high on auto.

auto is usually high to ensure stability. start there and work your way down.
