Hello i buyed the game today and from the first moment of playing im discovering that my cpu (r5 5800x3d) is at a really high and unusual temp 75-80c , usually i play more heavy games and i dont reach these temps, and sometimes i hear the cpu fans going so fast that the noise is insane, idk why is that , i tried changing graphics settings,but it wont matter, and for the gpu (rtx 2070s) i have no problem whatsoever…

Yeah I would be careful. I’m pretty sure this game just melted down my CPU or GPU. Not sure yet as my pc won’t turn on after it randomly shut off while playing earlier. Never had a single problem with any other game. 3070ti, i7-4790k, 32GB RAM, liquid cooling for hardware, no dust or hair in the case, and it gets torched by Diablo

5800X3D here too, with a Dark Rock Pro 4.
Temps while playing D4 range between 70-80° but can sometimes spike for a few seconds.
Highest i saw in Afterburner OSD was 90° in the character select after booting up the game.
This is really not high for a 5800X3D, they get pretty hot under load.
Had a 3900X before which got even hotter but was only half as fast 
Better graphics don’t mean higher CPU-usage, that depends on the type of game and engine used.
Most modern games are actually rather light on the CPU because consoles first with their weaker 3rd gen Ryzen.
A game can not melt down anything unless the cooling is insufficient or there is a faulty component like a old or low quality PSU.
If your watercooling is working properly then you should never have any problems with stabilty even under 100% load over longer periods of time (prime95, cinebench, furmark etc).

I’m having a problem with temperatures on my Ryzen 7 5800X. My temperatures are otherwise fine (in the 60°C to 70°C range) but occasionally they’ll spike up to around 85°C for a few seconds, which makes my computer fans go mental.
Makes playing the game a bit stressful when I have to be constantly monitoring my CPU temperatures to make sure my computer doesn’t fry itself.
I’ve seen several posts on Reddit about this and I also made my own thread here.
That’s not dangerous for the cpu though.
It can handle up to 95° if you check AMDs own specsheet.
Obviously it should not be running at a constant 90°+ but 85 for a short period is no problem.
If your system is stable and the cooling is sufficient, there is no need to worry imho.
My 5800X3D spiked to 90° for a few seconds in the character select screen once but during normal gameplay it’s usually in the 70s and if i open the inventory or a vendor ui than it goes up to 80-82°.
There is definately a problem with the engine with the cpu load, besides the bad memory management.

I’m aware, but it’s still quite jarring when your fans keep going mental every couple of seconds/minutes, especially considering how nothing is happening on the screen that would warrant such.
It would also be disingenuous to claim that this isn’t eating into the CPU’s lifespan unnecessarily and causing system instability for some players.
While i agree that it is totally unnecessary, it may actually be a good thing for some because it is a wakeup call that they need to fix/improve their cooling to prevent future damage of their components.
Every summer it is the same, so many threads about overheating CPU/GPUs, but most people are ignorant and blame the game instead of themselves or the manufacturer of their prebuilt PC (prebuilt cooling… yuck 
)
I live in Finland and it’s not even that hot here yet, so blaming the weather is completely disingenuous, sorry to say.
We’ve actually had an unusually cold start to our summer. It was rainy and almost below 10°C for several days in a row, and yet the temperature problems were present the entire time.
Oh so it’s brainless because summer does not exist outside of Finland and people with bad cooling don’t have overheating issues every time it gets warmer?
Maybe you should not take everything personal.
That was some poor wording on my part, I didn’t mean to come across as hostile, sorry.
However, I do still maintain that blaming the current season on these temperature fluctuations is disingenuous and does not add up. Not to mention there are reports of this bug occurring during the testing period in spring.
I don’t blame it on overheating alone since the game has several issues of which i myself experience(d) some and still do.
Just saying that some people who blame the game have in reality an issue with their components (cooling or else) which they don’t even bother with fixing first.
It is no secret that many prebuild PCs (Dell says hello) have severe cooling issues and often people who buy these PCs don’t have the technical expertise to figure out these isses by themselves.
I’ve noticed Diablo IV is torturous for my 5800X3D as well.
I’ve been loading hwinfo before firing the game up and at some point while in the game the CPU reaches 89.5C
However, my entire system while playing the game rarely goes above 30% CPU utilization. I run my 5800X3D at -25 PBO offset as well to run even cooler than normal.
I run my 3090 at 60% TDP to keep heat down to a manageable level, around 250 watts. I still get 120FPS in 4K with DLSS Balanced enabled with everything else on ultra.
I’ve never played a game that used a minimal amount of CPU that caused so much heat.
I can only imagine it’s due to the game hitting the big CPU cache like mad that’s causing it to heat up so much.
I would just like to point out that temperatures of 75-80, while high, are perfectly normal load temperatures for a high CPU intensive game.
These temperatures wont damage your CPU, although may reduce the expected lifetime of the CPU by a little bit if run consistently at these temperatures.
That’s why it’s important to invest in a cooler that is rated for, or ABOVE your CPU’s TDP. These values are listed for your CPU model and your cooler model. Also keep your cooler cleaned from dust, as this greatly reduces cooling performance.
Improperly mounted coolers will also severely impact the cooling performance.
So will bad or old/expired thermal paste, so make sure you replace it every 1-3 years.
Make sure the CPU has full coverage of thermal paste, majority of people add too little thermal paste.
If you don’t maintain proper airflow in your chassi, your GPU will heat up your CPU over time as well. Proper airflow can reduce CPU temps by around 10 degrees during load.
It’s also important to note that if your computer ever reaches CPU temperatures that are dangerous to the CPU, it will shut down your PC to protect the CPU before it is damaged (somewhere around 90-95c). This is a built-in feature in your bios. So while this is something we had to worry about in the late 90’s, it’s not a problem anymore.
I have a cooler that’s not rated for my CPU, but I do maintain amazing airflow in my PC, so my Ryzen 5600X, while only at 37% utilization, sits at 80c in D4, peaking at 85c.
This is perfectly normal for me, since my cooler is not rated for my CPU + it’s summer time so my apartment is sitting at 25c. A 6 degree rise in the ambient temperature will be a 5~6 degree rise in the CPU temperature.
Edit:
I suppose it’s also worth mentioning that the Ryzen x3D models (perhaps specifically the 5800X3D model) are running very hot as it is.
