The best option i think is vega(that runs cooler than 580x) and that i9 that turns out has integrated thermal cooling and it self runs 10C cooler than the old gen i7
Got a tip for us?

2019 iMac w/i9 + 2017 thermal design = iFurnace?

The main reason is that the iMac Pro, being SSD only, recovered a fair bit of volume that could be used for improved cooling design. Since we still have spinners, that volume is not available.
Also, adopting the Pro's style of cooling would like result in a motherboard design that would end easily-replaceable RAM. So you'd have to buy the RAM up-front and you can guess how well that will go over with folks.
The iMP has different internals, like no spinning HDs so an exact case usage scenario wouldn't work for the '19 iMac.

This is the route I am going, and I am actually happy there is no T2 chip. This is because I am an audio guy and that little bugger has been a terrible nuisance.
At that point it's basically an iMac Pro without Xeons, ECC memory, T2(which some people would prefer that was gone).

They have to get rid of the spinners anyway and customers might accept it if they also offer some real improvements which would be possible with the Pro body. The RAM part is a problem that might be solvable with good engineering...
I agree that Apple is eventually going to want to get the iMac on the Tx series chips and that will require them to drop HDD/Fusion drives because the T1 and T2 only support flash memory (SSD) and Apple has shown no signs of trying to get them to work with Fusion Drives/HDDs.

The CPUs and GPUs are down-clocked a couple-hundred megahertz from the "retail" models and I have not heard of reports of their being thermal throttling from scores of users who have spoken about or posted about their experiences loading the machines up with work.
He means the retail models of the same CPU and GPU components that you can buy and put into your PCs. Apple had to downclock those, probably in order to fit inside a limited heat envelop of the iMac Pro.
And I am positive that I have seen throttling reports of the iMac Pro somewhere, though it is nowhere near as severe as the MBP or the regular iMac.
I could care less about a redesign. There’s nothing wrong with the design. Why introduce new potential problems? I’d much rather have rock solid stability.

Sure, why not? I love to hear people’s thoughts.You don’t really need us to answer that question, do you?!
the i9 imac uses an I9-9900KF, slightly different than the usual K cpu. But its 4W higher TDP than the previous i7-7700 was in the 2017. So yeah, heat problems will continue.

which always blew my mind. shouldnt it have been the other way around? how many people actually upgrade their iMac ram?

I do. 64GB self installed every time. I kind of like saving about $500
And we still do not know anything about the internals of this machine yet. Maybe they are using a better heat sink copper design, thermal paste, fan, or something.

On this forum? Probably a not-insignificant number because we're techies.
In the general audience? Probably not many, to be honest because they would rather have it all from Apple and all under one warranty.
When I bought my 2017 5K there was a shortage of RAM in the retail market so it was almost as expensive to upgrade from 8GB to 16GB myself as it was from Apple so I went Apple. But for my 2011 and 2013 models, I did upgrade the RAM myself.
It's the same i9-9900 but without the integrated graphic.

Not exactly solved, just a side step.
CPU will throttle hard once it hits 95C and bounce back up until it hits that temp again, repeat process.
Apple put a very gentle fan curve and let the CPU's temp go near its thermal limit. They have decided low noise over performance & cooling.
Good engineering can't replace the law of physics. Without contacts of memory sockets, you can take memory with higher speed.
The RAM in the iMac Pro sits also in sockets but the case has no openings to reach them without out removing the display. If the had used the Pro case for the new iMac they might have found a better place for the sockets to reach them with a door....
