Recently started using unreal engine 5 and following this tutorial by unreal sensei Unreal Engine 5 Beginner Tutorial - UE5 Starter Course - YouTube , gpu is overheating {82 to 85C} while making / sculpting landsacpe & crashed 4 times { tutorial timestamp - 3:34:41, system specs i9-9900kf & rtx 2080 ti , 128gb ram {air cooling cooler master hyper 212}
That’s a pretty normal temp for GPU. What error do you get on crash?
Have you looked at CPU temp also?
You could try changing you’re scaleability settings if you haven’t already, cpu + gpu usage is a lot less
Greetings @Barry_AllenX
Welcome to the Unreal Engine forums! I’ve had quite a bit of experience working with GPU temps myself. 82-85 is pretty warm. But, should still be within safe temperatures assuming it’s not sitting at 85 all the time(During normal use). Within Unreal Engine, you could consider changing your engine scalability as Moose suggested.
If you’re looking at additional options to help cooling outside of Unreal Engine, there are a few things you could look into. I’d check out my case and ensure airflow is good, keep the room temperature cool as well. I went in on my newest build and actually changed the curve on my GPU fan settings in my BIOS. I also got MSI Afterburner and manually set the fan speeds up high to run when I was doing heavy tasks. Doing those two things dropped my GPU temps by about 15 degrees. I can’t recommend those as official solutions as they aren’t from Epic/Unreal Engine. But, it’s something you could look into if you needed additional help with the temps. I hope this helps!

Hi Frosty
I’m currently facing a concerning issue with my MacBook Pro with the Apple M2 Max chip and 64 GB Memory. Whenever I launch Unreal Engine, the system rapidly overheats, reaching temperatures as high as 110°C and beyond. The heat is so intense that even the keyboard becomes untouchable. I’ve experimented with various Unreal Engine versions and updates, and I’ve ensured that my macOS is up-to-date. Surprisingly, I don’t have similar problems with other software like C4D, Blender, and After Effects eventhough I rendered and work on many highly CPU/GPU demanding project
I would greatly appreciate any insights or suggestions to resolve this issue.
Thank you
There could be a few reasons for that happening. UE is very intensive, specifically on the CPU side of things if you’re loading shaders and such. I usually recommend checking your system first and considering changing your fan speed curves. You can also do some things with the settings for UE to help. Here’s a post where a couple of users were discussing those options. Forum Post You mentioned that you tried this in other versions. Does it overheat in all of them? If so, what tasks are you performing when it overheats? Thanks!
I have reduced my GPU temperature from ~83° to 60-65° by doing two things: first, I reduced the quality of the viewport picture by going to Settings → Engine Scalability Settings and setting it to “low”; second, I limited the FPS, which doesn’t need to be high while I’m learning new stuff, to the lowest possible 15 FPS by going to Edit → Project Settings → searching for the term “frame rate” → setting a fixed FPS rate under the “Engine - General Settings” group.
You can consider multiple things
-
Disable Lumen and Nanite and switch back to screenspace global illumination/no global illumination atleast when developing
-
Lower scalability settings when developing
-
Check whether your gpu fans are working as they should and clean off any dust
-
Install NVIDIA Studio Ready driver instead of Game Ready Driver (It supposedly helps/improves performance with studio applications like blender/unreal engine)
I wouldn’t recommend capping framerates however. I personally experienced weird issues when capping framerates such as with each window open in unreal engine, UE becoming more unresponsive and framerates halving.
Other than that, one thing I personally do is using MSI Afterburner to undervolt my GPU (lowers temperatures and coil whine which I experience on my RTX 3070).
