I don't think Intel in general would want to even set a precedent explicitly and specifically addressing rumors from MILD and equivalents.

Intel Arc A750 & A770 Unboxing & Preview
The Arc A770 Limited Edition and Arc A750 represent the very best Intel is offering for the Arc Alchemist Architecture. Our two review samples came in a huge box with a delightful set of goodies. Here's how everything looks IRL, while you wait for our in-depth performance reviews of both cards.

They're actually using a vapor chamber for a card in this cost and power class. Interestingly it seems like the heatsink+shroud is slightly less than 2 slots thick. Will be interesting to see how it functions.

Damn, if it had a blower fan and exhausted out of the back, I might have taken a chance on one for my media PC.

An Alluring Alchemist: Intel Arc A380 GPU Creator Performance Review
Ahead of the launch of the upcoming Intel Arc flagship, A770, we wanted to kick off our Arc creator coverage with an in-depth performance look at a wide-range of real-world scenarios - from encoding to rendering to photogrammetry. What does a $140 option from Intel grant you? We have many...

If Alchemist scales relatively close to tflops in Blender (like RNDA2 and Nvidia in CUDA) and similar workloads than the A770 16GB would have very high value in theory as it carries x4 + the tflops of the A380 tested here, as long as the software support is there.
I'm still waiting on independent benchmarks before I go all in on the happy celebration. I want to believe, but I gotta see proof first.

They're basically throwing a lot of raw hardware at you for the price. So I wouldn't be surprised if you took aggregate benchmarks for current mainstream/popular games/software that it does relatively well. Also technically neither AMD or Nvidia have released their next gen products at this segment and are likely still months out.
A large concern that reviews won't show is what the actual long term support prospect will be from both Intel themselves and software developers.
Another would be how much variance and issues crop up if you expand the usage criteria if you aren't just using more mainstream/modern games (or other software).

That's the big one I'm waiting to see about on the 770.
Intel® Arc™ Graphics - Resizable BAR
What’s that oddly-named feature called “Resizable BAR” all about? Why does it matter? Don’t fear the ReBAR because TAP and Ryan have all the details in their latest video.

I get the sense that their PCIe and/or memory controllers are just not capable of enough transactions in flight simultaneously, or the latency between transactions too high that it craters the throughput. Tough to say why, might just be that this is their first dGPU memory controller since the i740 and they probably don't have much experience working with GDDR in any of its forms.
Think about how you'd approach a blank-sheet design for storage. If you knew you had the SATA bus as one of your constraints, and you knew you wanted to be able to transfer data at, say, ~200MiB/s, you could achieve that with either a mechanical HDD or an SSD. If late in the game you suddenly realized that you also needed to be able to sustain that 200MiB/s not with sequential multi-gigabyte file transfers but with tens of thousands of tiny 4k file transfers... if you'd started down the HDD path for cost reasons and had locked that into your product, you'd now be in big trouble.
My complete speculation is that the same sort of thing may have happened here - like if the systems they were using during development all had ReBAR. They may have gotten far enough into the physical layout before they really understood what the tradeoffs were for only optimizing for those large transfers. Not enough die area spent on FIFOs/buffers, or on really optimizing out every scrap of latency they could find, that sort of thing. It's hard to believe that it was an intentional tradeoff to just completely abandon all the older non-ReBAR systems, even AMD and NV's smallest GPUs over the years haven't seemed to have issues, so it may just be that it wasn't obvious how bad the issue was until late in the game.
Something they thought was a good idea during design but didn't forsea this issue.
So hardware related that they may be able to help in driver but don't buy expecting it to improve.
They've talked about it a few times.
Good explanation

These are 225W TDP cards, so I'm not sure how well a single radial blower would be from a noise perspective.
Acer will have a hybrid model with a radial fan and a smaller axial fan -

Intel Open To Usability of Arc Gaming GPUs In Data Centers & Servers
Intel seems to be open to the use of its Arc Gaming GPUs in data centers & servers as pointed out in a recent interview with ServerTheHome.
wccftech.com
I remember blower-cooled R290(X) gpus. I think they reached close to 100c under gaming loads.
They are 300W cards and AMD had the fan control setup to target 95C. It was the same cooler as on the 7970, which was a ~ 250W card. I had a 290X for awhile and it was a very noisy card, and annoying because the fan changed speed too much. It would even ramp up rendering the WIndows GUI sometimes.
I suggest avoiding blowers unless you need to put a card into an enclosure without much airflow. That's what they are best for. They won't be a quiet solution unless the card is much lower power and the cooler still kept beefy.
