New Amd user temps

I have always been an Intel fan boy when building pc systems but I made a short break after selling my 12700k setup to go over to a Mac which I hated. I now have built myself another pc system using:-

Msi b850 tomahawk
9700x
Artic freezer 36
Liam li 217 case
Corsair 6000mhz cl30 32gb
Wd 2tb nvme gen5
Pallit GeForce 5070
Corsair rmx850

My 12700k with air cooler always idled around 35c but for the life of me cannot get this amd chip below 45c on idle with pbo enabled it jumps well over 80c just using cpuz benchmark.
I have tried different methods with -20 on all cores which helped a little but not idle temps. Only way to stop the high temps is to disable pbo, I am sure on my 12700k I just left most things on auto in the bios and was great and gave a higher cpu multi score than this 9700x.
Is this cooler which I have fitted correctly not a good choice for this cpu or is there other settings I should be making within the bios?

Those temps are normal, it takes a while to get used to especially coming from older Intel setups.

Ryzen are always hot chips. Those idle temps are fine. Okay cheers, just stressing for no reason then.

Okay then that is good to hear, I'll start to use the system now after messing with settings in bios for last 2 days with no success.

With my 7800X3D I set thermal limit in BIOS to 65c and it still boosts to 5050Mhz and temps top out at around 68c under full load. Also check what the SoC voltage is at in something like HWiNFO64, MSI seems to use 1.3v while most other brands are at 1.2v-1.25v. On my MSI MAG Tomahawk X670E I have set SoC Override in BIOS to 1.15v and the system runs cooler than Auto but in this weather its still idling around 40c+ under a 360mm AIO. Was around 38c idle before the weather warmed up and that was under my old 240mm AIO.

Thank you matey
 
My 7800x3D runs idle at 45c. But I barley ever see it go above 65c under full load. This is with a 240mm aio.
No bios tweaks at all, and has been rock solid for over a year.
I did try with my spare Noctua Chroma 120mm cooler and no difference at all.
Obviously case airflow can be a big factor. Personally I am running in a Corsair 3000D with the specs in my sig and 3x 120mm fans at the front, the aio as output on the top and 1x 120mm exhaust on the rear.

I come from a Intel 9700K, which was quite toasty anyway.
But has others have said. All quite normal :)
 
Yea I've got a few 7000 series chips and just built a 9800X3D for a friend, these temps are pretty normal, nothing to worry about.
 
What is annoying is that even though the latest CPUS are build to run this hot i have found motherboard manufacturers have not altered the fan curve to take into consideration these new temps.
 
vaguely on topic
do zen 4 run significantly hotter than zen 3?
my room is usually around 20-21 say 22 just for worst case
im running a 5900x on air [noctua ndh15] and at idle i usually have upper 30s sometimes up to 41 so call it 42/43 just to be on the safer side
by idle i mean not doing a lot two screens one with yt open [watching the voodoo gpu video someone posted on this forum earlier] and the other with brave open about 20 tabs [lol] messenger and whatsapp
but not doing anything intensive
it rarely goes above mid 50s even under heavy load
I'm genuinely questioning if my temperature sensors are inaccurate or something half joking half serious
half expecting to be accused of lying on this as well lol and im very willing to accept theres something im missing and im actually a full 10 degrees warmer than its saying

Yes, I think it would be fair to say that each generation is hotter than the last (it depends on the CPU), though Zen 5 is supposed to be a little cooler running than Zen 4.

2x CCDs can also run cooler than a single CCD, especially if the single CCD has high clocks (like the 5800X).
 
im also running most of it at stock out of the box settings which probably helps i was just worried that the sensor was duff
so those temperatures dont sound like a politician stated them? lol ie at least vaguely believable?

TPU got 67 in Blender, with a U14S, which I believe is only a single tower, so while it does seem low, it is not impossible.
