And you know that how? Because it only affects a low percentage of people?
I have a beefy PC, been playing lot of the latest games on Ultra settings in 1440p 144 locked, with no problem at all. Diablo is not a demanding game by any means, even by Blizzards requirements.
The problem here is, that it affects the minority, so its not a issue that anyone will rush to fix.
Because any heavy load will cause this. Played crisis lately?
If thatās too old, how about you run prime95 and furmark at the same some? See your temperatures then.
So, I reiterate again, overheating is a common issue not tied with any particular game or piece of software. Donāt want overheat? Decrease TDP, disable CPU boosting, buy non-factory-overclocked GPU, improve your PC cooling. But donāt say in some random game forum hey this game is heating my PC 
IT MEANT TO, itās a 2023 computer game dude.
Diablo is not demanding? Why all these folks report high temperatures on their CPU and GPU then? Game is just heating up hardware so itās more cozy?
Dude, if you have no idea what you are talking about, you donāt have to reply, its fine.
But saying stuff like āthis is a 2023 game ITS MEANT TO heat your PCā, speaks of how clueless you are. And its fine, you donāt have to have a clue. But trying to be a smartass while you have no idea what you are talking about, makes you look like an idiot.
But just to humor you, iāve run all the decent benchmarks, including prime 95s torture stress test, and what do you know, everything was fine.
And thatās what we are trying to figure out. We have people who had problems since beta, people since launch, and people like me and my friend who started overheating + crashing ONLY AFTER THE LATEST PATCH. Was the caps lock enough or do you need a picture to understand what iām typing ?
Your ā2023 gameā has CPU requirements that are 5 years old and GPUs that are 3 years old. And btw iām not even talking about 4k, so that lowers the requirements even more.
So no, Diablo is not that demanding for a ā2023ā game. And no, it is not supposed to make the game crash, due to heating, on a modern system, that only started happening for me personally after their latest patch, while being the one and ONLY piece of software that does that.
Itās not that demanding yet people are reporting max temperatures on GPU and CPU? Lol dude. I already said that in my previous post and you obvsly keep saying how not demanding the game is. Literally tetris-like or mahjong requirements demand - game. Of course.
So your PC is overheating after all. Well, maybe fix that first before you blame the game?
I donāt know if the latest patch changed anything, because for me, it works just fine. Just like in beta. If for you doesnāt, then you need to troubleshoot your hardware first to make sure itās not bloody overheating. 
Have fun, end of discussion from my end (ignored 
)
I wonder if i send you a captcha if youāll be able to solve it or not, because aināt no way you are a functional human being.
Please donāt participate in conversation if you have nothing to add or lack knowledge.
Of course room temp plays a big factor.
Limit FPS. Without FPS limit it will melt GPU video memory. Mine was throttling and reaching 105C.
I have issues with high CPU temperatures in Diablo 4 only as well. This hasnāt changed since the beta. On my wifeās and my own system, the GPU temperatures are fine (never exceeded 58Ā° C on my 4090) but the CPU temps spike sporadically into the high 80s causing the systems to sound like jet engines because all fans are going berserk.
In dungeons or open world stuff like helltides this isnāt really a factor and starts happening mainly when entering a town.
The systems are in cases with decent airflow and donāt exhibit those effects in any other game ā including demanding ones like cyberpunk 2077 with maxed out settings.
System specs are as follows:
System 1:
Core I9 13900k
Asus ROG Maximus Z790 Hero
64GB of GSkill DDR5-5600
Samsung 990 Pro 2TB SSD
Asus ROG Strix RTX 4090
Case is a Corsair 7000D Airflow with 4x140mm Noctua Fans (plus the 3 Fans from the AIO)
CPU Cooler: Arctic Liquid Freezer II -420mm AIO (top mounted with fans pushing from the inside out)
System 2 (the older system):
Core I9-9900K
Asus TUF Z390-Pro Gaming
32GB of Corsair DDR4-3200
Samsung 970 Pro 1TB SSD
MSI RTX 2080Ti
Case is a Corsair Obsidian 750D Airflow Edition with 6 140mm Noctua Fans
CPU Cooler: Noctua NH-D15 chromax black (the system is over three years old but the cpu cooler is new and freshly pasted as well)
Both systems run the latest game ready nvidia driver and on both systems fps is limited to 144fps in the driver.
Both systems work fine in other games and for work and there are never any spikes in CPU temperature as in Diablo 4. When Iām in town there are temperatures that rival a cinebench load although not totally constant but recurring in short spikes.
Just wanted to get my experiences out here for people in similar circumstances to see, that they are not alone. The experience of other family members and friends varies in regard to CPU temps. In some systems (even lower specced ones with core i5s) everything is fine even in town and in others there are the same temperature spikes that can be seen in our two systems.
My case is curious, I canāt put fps limit over 100 fps or the card goes from 50-54 degrees to 82 in a few seconds.
Iām not saying 120fps iām saying 101, only one fps more. I can understand that the bricked cards probably had previous damages, but some bug or bad GPU resources management from software is there for sure.
I understand that enabling Reflex you are demanding a lot from the system, I can live without it, I also tried in lowest quality 165 framesā¦ 82Āŗ, low quality 120fps 82Āŗ, low quality 101fps surpriseā¦ 82Āŗā¦ low quality 100fps or less 50-53Āŗā¦ ultra quality (without reflex and dlss) 100fps 50-53Āŗā¦
I will play at 100fps, is not a really big dealā¦ but pleaseā¦ keep seeking the faultā¦ I can play more demanding games and renders without reach this temperaturesā¦
My card:
HP 3080 10GB
New thermal pads and thermal paste from noctua changed less than a month.
Edited: Something I forgot to mentionā¦ these temperatures are in any part of the gameā¦ starting on character choose screen, on any city or playing with a lot of mobsā¦
82Āŗ on character choosingā¦ what are you doing on background process?
Edit 2: Opening the inventory
Before open: 50Āŗ
While the inventory window is open: 82Āŗ
Mateā¦ this is a software issueā¦
1% CPU Utilization but CPU burns at 90 degrees celsius, something wrong with this game, its on a r5 5600x a 85 watt cpu with an overkill 360 AIO on it, which works fine for any other game.
Edit: Seems like closing the Blizzard Launcher dropped 20 degrees lol
If your CPU is at 1% utilization then youāre not even running the gameā¦ nice try 
Nvidia series 3k have an issue with Diablo IV, there are youtube videos about it already, just check it out, cpuās going 100%, temps skyrocketing, vrams locking to max with freezes and reboots.
Regardless of having top of the line specs with awesome cooling or no, the game has issues that need to be addressed.
Turning off Reflex fixed it for me, went from 88c to 60c. Thatās crazy.
EVGA 3070ti ftw3
Well considering its making ps5s overheat everywhere as well, all of you saying its a hardware issue are wrong. Consoles are bricking they are getting so hot. This game is wrecking peoples equipment and they are being completley silent.
How about starting to give some feedback ,blizzard?
I used to have the problem only when opening any vendor menu, now its even worse.
Wtf are you doing?
Can anyone spell class action for me?
I have posted the same on other similar topics. Adding it here for better visibility:
The game seem to use the drivers to auto overclock both CPU and GPU when in vendor screen. This can cause high temps/instability.
If your CPU does not allow OC, then you will not be affected.
In my case (Ryzen 5700x and Nvidia 3070) the CPU was overclocked by 50Hz: from 4.6 to 4.65 and GPU by 135Hz: from 1815 to 1950.
I was able to solve the issue for the CPU by disabling CBS in Bios, but this only works for AMD CPUs and will completely disable boost.
For the GPU I have limited the power using MSI afterburner to 72% (you may need a different percentage, depending on the GPU type and make)
Please note that my PBO was disabled in BIOS and also the framerate was capped at 60.
Blizzard, please fix this issue.
I hope this helps.
Amd Ryzen 7 5800x3d with Sapphire RX6800 here.
The GPU AIR fans are running on 50% and the heat is on 51C
Cpu has hydro cooler Corsair H150i RGP Pro , fans are running on Extreme mode (scaling depend on temperature) , max temp i get is 60C cause we got 34C outside and the room doesnāt have air-condition (yet)
Forgot to write , Frames are on fix 165 (it reaches 140 to 164) , connection with monitor is d-port 1.8 and the monitor is samsung g5 odyssey 34 / 3440x1440
(the above are on HIGH quality preset , when i was playing on ULTRA it was 3 degrees higher on GPU and same on CPU)
You should really chk your hardware brother , also It hardware admin here .
I have a RTX 2070, it is over heating as well, only while playing diabo 4, every other game i played it doesnāt happen, I have a ultra wide monitor with a native res of 5120 x 1440.
the last thing I tried was to lower the screen res (my ultra wide has PNP so i just split the screen with my PlayStation on one side and pc on other) and that helped a lot, the temps hardly get to 70c now but still, I shouldnāt have to go that route at all, every other game I have played since buying the Ultra wide works fine, no over heating. hell, playing diablo on playstation 5 works better than on PC and every playstation I have ever owned gets freaking hot.
