My GPU is running hot
I've got a Nvidia 2070. I know it's not new anymore, but I need to run this game on low at 30 frames a second to keep my CPU under 70 degrees

Is there something I'm missing here, or is the game just poorly optimized?

Why would you want to keep your CPU at under 70 degrees? That's a low to normal temperature for a CPU under load (if you're talking about degrees Celsius), or unbelievably cool (if you're talking about Fahrenheit, which is probably not the case).

Also, you're saying that your _GPU_ is running hot, but then say that you want to keep your _CPU_ at under 70 degrees?

If you're talking about your GPU (not CPU), then the intended max temperature under load (as far as I'm aware, I haven't checked the details) is 88°C or 90°C for that generation of graphics cards.

Because when my GPU is over 70 degrees (which is easy to do at high settings on 99% of games) my fans start sounding like a jet engine

Hmm, sounds like your fan curve is too aggressive. Fans don't need to go full speed to keep a GPU at 70°C, 80 would be totally fine. Even at 85 there probably wouldn't be thermal throttling yet, but that's cutting it close. I'd tweak the fan curve a bit.

But to answer your initial question:

The game currently does put more load on GPUs than many players expect. There's no official explanation as to why, but several possibilities exist:

- It's possible that the GPU handles parts of the simulation. That would make sense - GPUs are powerful hardware, and are increasingly used for tasks that have nothing to do with graphics. Cryptomining was the application that made this change apparent for the mass audience, but that's far from the only one. (And no, this game does not sneak a cryptomine on your machine, in case my example got you worried. ;) )

- It's possible that the game's graphics engine is currently written with a focus on making it work, and that optimization comes later. That would make sense for an Early Access product.

- It's possible that players underestimate how much graphics power a large, very detailed world with voxel graphics (houses with up to 21 floors, with every apartment having its own individual layout) requires. Voxel graphics may look clunky, but that doesn't know that they are necessarily easily easy to process in a world of that size.

All that said, however, I don't think it makes much sense to buy hardware that you don't want to fully utilize due to noise levels. I'd either buy a card with better cooling, or (if money is tight) save money by buying a cheaper card that I _can_ fully utilize. But it seems that this advice is coming years too late - might be worth making it a factor for your next purchase, though.

I use such a support that you put under your laptop that has integraterd fans, it helps a lot and those don't make noise.

that sounds like misconfigured fan speed settings

70deg is really cool for a cpu under load

One small thing about this: I think it's unlikely that the GPU handles world simulation only because the GPU would already be under load and the GPU wouldn't have enough spare memory for anything useful

GPUs are generally very good at doing one task at a time, even if those tasks are incredibly intensive, whereas CPUs are better for several hundred simultaneous tasks (simulation)
