I'm using NZXT Kraken 72 fro cooling AMD Threadripper 3970X.
I'm not sure if the temperatures are okay or a bit too high and I should reapply TIM again (I did whole CPU surface thermal paste spread method). Basically when idle (or watching youtube) temps are fluctuating between 36 - 50C. Also clock is also all the time fluctuating 3850 - 4050. Is it all normal behavior?

Yes and watching youtube is not idle activity. There is quite a bit of video decompression happening in the CPU from the YT stream. Any spike in a core will generate heat. Idle is like sitting there not watching, listening, or even moving the mouse. Even then background processes prevent true idle. Chip is always working.

My 3960x performs exactly the same as you are explaining.

Your chip and cooling are working fine and everything is nominal from what you are reporting.

Though you didn't mention peak temperatures. What are those like under heavy load? Thats the real tests of your thermal solution and application of paste.

So far when rendering in Corona it was around 75 max

Also, the temps you are seeing are peak temps per core and not an average temp. That's why it looks like its fluctuating like crazy. 75c in corona is passable if it was the bench.

I will add this ... the design temperature at stock for the 60/70x is 68c. Your CPU should not surpass this temperature under the heaviest load if left at stock. However 75c is not that hot. I would possibly look into airflow into the case, or airflow into the radiator. If your using an AIO just make sure you have a very thin layer of TIM on the hotplate of the AIO. Youre still fine though. That was just if you want to be nit picky.

I do NOT suprass 68c under any metric so far as long as my radiator fans are blowing. I have 7x120mm worth of radiators.

hi, i use a Noctua NH-U14S TR4-SP3 mounted with thermal grizzly conductonaut.
out of the box (no overclocking) my temperature raises in seconds but doesnt seem to exceed 76C.
tested with 40mins rendering in cinema4d

my nzxt 510 is small and it is hard to get the hot air out...
there is only one top case out and it is blocked by the motherboard (asus zenith II)
maybe another case and more fans would help

So this is something I'm trying to figure out as well with my 3960x as it idles in the 50's as well. I suspected that my 128 GB's of memory overclock and tighter timings was the culprit, but I'm leaning way over to needing a better cooling solution. I spent the day running cinebench R20 at different memory clock speeds from 2933 up to the highest stable clock I've managed at 3400 with 14-15-15-15-30 timings. The memory settings made no difference on my idle temps as they stuck around 53 degrees through all the tests. What's more, all those settings didn't change my score which stayed just above 13400 the whole time (and that's strange to me as I thought the chip infinity fabric would play a bigger role in that test). So I have to rule my memory timings out as a cause... and that needle is pointing more to my cooling solution, a castle 360ex AIO. Just to make sure, I fiddled with CPU core and SOC voltages, trimming them down with still no changes to my idle temps. Then I took a closer look at what ryzen master was showing, and like your situation all the cores were just jumping around staying busy, so started closing background tasks... and after closing Corsair's iCUE, temp drop 5% right there and the CPU was a lot less active at idle. I run a rainmeter display as well, and when I shut down that and the HWinfo app feeding the data, dropped another 3%. So, while taking out some background tasks help, I still have a cooling problem if those minor tasks caused an almost 10% jump in temps. Running those cinebench R20 benchmarks, I was maxing out at 83 degrees which is still too high for me. I'm going to reapply the thermal paste although I doubt that's the problem.

The website does indicate a max temp of 68 degrees C, but I have to wonder if that's the same temp measure/sensor used by Ryzen Master, as the temp meter in there doesn't turn yellow until 80 degrees and not red until like 90 degrees, and it also indicates a maximum of 95 degrees... at which time I think the chip throttles.

I don't have a threadripper, but the temps your talking about mimic pretty closely to the desktop variants.

my 3960x at stock runs like 50-60 and at 4.45 hits 65-70 on custom water. These things run cool when you think how much power they ues when clocked high my psu shows about 350-400w at 1.38-1.4 v core

you should run the same bench as OP at stock, then neuter your fan curve and rerun the bench at higher temps.
Compare core clocks vs frametime at either temp.
I don’t think anyone has uploaded a clip to YouTube with 3960x.

There’s tons of air cooler and aio tests for Ryzen:

I was also doing some testing because I was wondering why cpu when in low use doesn't underclock. My temps after long use are around 50 when idle and hits 82 when heavy rendering (Kraken 72x AIO).
Figure out when setting in windows power settings to saving power than finally CPU is undercloking to 2.18GHZ and temps are 40 max when idle and aren't as jumpy. But then CPU barely hits 4GHZ when doing heavy tasks so also not too good.
BTW I have Lian Li o11dynamic xl rog case with 9 (3 on aio) noctua nf-a12x25 fans so no problem with moving air inside.

Those are idle temps for you? Those 50+ temps are what I'm seeing as well at stock although I'm not using custom water... I'm thinking I'm not getting the water flow I'm supposed to be getting even though it is maxed out at 100% DC, so maybe a weak/failing pump. Whisper quite at 100%, but maybe that's the temp trade off. You're spot on when put into perspective though as these things are all relative to the the power these chips hold. I don't intend to overclock, at least with my current aio.

Yep, sounds like my chip as well... my motherboard has a lot of power control settings like AI control (has the DOCP/XMP setting), performance, TPU, and that precision boost overclock and heck I don't know what half those things do so I leave them at defaults which is usually auto. As I closed down background tasks, some of the cores actual went to sleep in Ryzen Master and my temps went down accordingly into the 40's. So it would seem that core voltages play a role but I just don't like gimping the CPU to reach lower temps. Maybe Asus will improve their AI over time to lower clocks in light loads.

're those temps with overclocking or stock?
with the noctua cooler, even with my not so well cooled case i get constant 76C with 40mins of rendering
with improved airflow it would be even better... (today i noticed that opening the case gets me 5C down, lol)

I'm running a 3970x on an ASUS Prime TRx40-PRO MB... Air cooled with a Noctua single fan in a Thermaltake case.. CPU is NOT over clocked but I did select the recommended overclock on the RAM.
CPU idles between 39C and 44C. During a "hard" Prime95 test it got to 81C and stabilized there. I'm quite impressed with the "cheap-o" air cooler.. My Intel based computers are water cooled (with simple AIOs) and they all run hotter than this.

I have ordered a second 140mm fan for the cooler and see if I can have load temps in the 70s

I have to think that's pretty good for a 3970X on air--are your room ambient temps pretty low too? Just to be clear, when you say stock, you mean at straight 3.8 MHz? I've been chasing this low temp ghost on my 3960X and so many variables seem to play into the equation, like the default motherboard bios setups which on mine (zenith II extreme) include a lot of "performance" and precision boosting settings on auto. I always considered "stock" not touching any settings, but that's just not the case anymore I think. Turning those off to a straight 3.8 MHz (the base clock stock), I'm idling at 35 C with the TR edition of the Thermaltake Floe Riing 360. When I run the Prime95 small FFTs for the maximum power, I'm getting to 81 C as well and on the smallest FFTs getting to 75 C. I see Asus is looking at releasing a 420mm TR aio, so there may be a new crop of coolers more suited to the new TR coming out over the next year.

Yes no tuning at all. just running the stock Clock speeds as per the stock settings on the MB. 3.8 Mz... The room temp is 21C with radiant floor heating. Right now the new PC is on the floor in the family room by the TV and the Fireplace. Oh and I used the stock thermal paste that came with the Noctua cooler too.. 13 blobs of it as per the instructions. 9 little blobs with 4 larger ones in between
The RAM is getting warm though.. it is simply 8 sticks of 8G Vengeance 3000Mhz that I had kicking around.

The fan(s) on the Noctua cooler are very close to the RAM and I had to move the fan so it sits proud of the cooler fins by about 1/4" (7mm)

The PRIME TRx40-Pro MB is marketed by ASUS as one that can be over clocked BUT it is the low end MB and most of the reviews recommend to pick others to use for overclocking for fear of overheating the VRM which has marginal cooling.

I now have a second fan on the Noctua air cooler..... Idle temps now range from 31C to 39C Now under full load The CPU temp maxes out at 73C (prime 95 "hard")
Lots of room for an overclock (if I was willing to risk it on my "low cost" MB

The noctua cool is not pretty, is not sexy, but it works and is not all that louder then a AIO..

You should get a water temp fitting and control fans/pump via water temp. Then you can ignore the cpu temp spikes since they are not averaged temp but individual cores spiking on load or perceived load.
