"Gaming laptops" are a lie anyway. You can't generate that much heat in that small of a space without something eventually going wrong, this applies to all of them. They're all hot and underpowered.
Yeah, I expect any gaming laptop to have a shorter lifespan, but killing three mobos in the span of 3.5 years shouldn’t happen. Now that I’m older and wiser, I wonder if I had a bad power supply, but that’s something that should have come up on my second repair.
I had that in a year with Asus/ROG, garbage.
They've gotten a bit better within the Nvidia 1000-3000 series, but I can't vouch for the 4000 series. Better thermal management techniques and lower target thresholds.
That being said, I'm sure there are manufacturers that buck the trend and set higher thermal targets for more performance. I'd say monitor your temps, and target for no higher than 75c if possible.
75c is impossible on a gaming laptop if you dont have a low power gpu (eg max q)
As in too high or too low? Maybe it might be that I've only had experience with a mobile 1060, 3060, and 3070 from Lenovo, but all of them seemed to have a target temp around 72-75, that or that was effectively where the fans could keep it at equilibrium when running furmark as a benchmark.
It really depends on the tdp. On my laptop which has a 2070 with up to 115 w and an 10th gen i7 with up to 45 w the cpu can go up to 95 deg and the gpu throttles at 86 deg.
Some laptops have Max q or low pwer versions of the same card which have a lower tdp and produce less heat. But for higher power gpus and CPUs they will most certainly go above 80.
Why not the steam deck then?
Different hardware type. Gaming laptops have dedicated graphics cards which generate heat from an additional source, and they have to drive 1080p/1440p/4k content, whereas the steam deck is a 1280x800 screen, which is absolutely perfect for an AMD integrated GPU with reduced thermal management.
The steam deck is a single spec tightly tuned machine and software package not unlike a game console, whereas a gaming laptop is an all purpose machine with hardware all over the spectrum that you can buy what you want/need.
