Need help with Zephyrus Duo 16 running hot

[Kael_Bot]

I have a Zephyrus Duo 16 (2022) (Ryzen 9 6900HX, 3080 Ti mobile, 64gb RAM, Gen 4 nvme SSD). At idle, the cpu temp is ~42°C. When I start up the game the temp starts to increase up to around 65°C. When I get into a fight, however, the temp jumps up to over 75°C, which causes a CTD.

I've done many things I've read about to help alleviate the cooling situation: cleaning out my fans; raising the backend so that there is more space for the fans to vent heat; used a high-quality laptop cooler (IETS GT500); reduced power limits (to 65W) and undervolted the CPU by -20 using GHelper (so much better than the crap Armoury Crate that came with the laptop).

Any other suggestions for how I might get a better handle on cooling would be greatly appreciated. I've also read across a number of forums that other people have had crashes with this laptop both in BG3 and in other apps because of poor cooling (whether they realize it or not), so I may be fighting an uphill battle with a laptop that has poor cooling design in the first place.

Here are links to screenshots of my GHelper settings:

Purely by design, laptops always have poorer cooling than Desktops. But that aside, you seem to have tried the logical options to reduce heat and to vent it asap.

Other than such physical things, the only other options to look at are software. Ensure that you have no other software running when you are gaming. Browsers, windows updates and AV software are the most common. But use Task Manager and remove or suspend any other software that is not needed.

Reducing the load on your CPU, and GPU will reduce heat. But beyond that you are simply stuck with a hot laptop. Unless anyone else has any better suggestions.

Share a video to clarify your issue.

Seems you have done all for cooling already. I guess you have also checked if thermal paste requires renewal.

Good point, but not so easy in a laptop.

75 degree on a cpu while gaming is not rare my air cooled Desktop 3600x hits 75 degree while gaming from time to time especially in the summer Months but it does so since 4 1/2 years and works perfectly fine.

yours is a laptop who by design gets hotter than a desktop. i would start worry if my cpu hits 80+ all the time but not before that

Yep, and it’s still good though I may replace it anyway with a higher quality thermal paste than was likely used in construction of the laptop.

I use HWINFO for sensor readings and one thing I noticed is that when at 75°C, the thermal limit for the GPU hits 100%. I imagine there’s a strong correlation to hitting and going over the thermal limit and crashing. Am I crazy in thinking that 75°C is a little low for a thermal limit on a gaming laptop that might be throttling the CPU?

I’m on my phone atm but if anyone is interested I can put the HWINFO log file for my last crash so you can see the raw numbers, how they correlate to the thermal limit, and about 100 other data points collected by HWINFO.

I’ll also see if I can capture a video of it. I use RTSS in conjunction with HWINFO to overlay some of the sensor in formation so I can see in real time when the heat rises and what I’m doing when it does. A video would definitely be helpful then in showing exactly what’s happening. Although I’m a little worried that running a video capture app along with BG3 would cause the CPU to heat up even faster.

Finally, as far as other background apps are concerned I use the surprisingly helpful Razer Cortex app to shutdown all non-essential processes when the game starts (it restores them when quitting, or in my case, crashing).
