I use a Delkin Black in my Z8 and when it’s hot outside and I’m doing fast shooting with flying birds I do get the hot card warning at times. The camera has never shut down and has anyone found a card that does not overheat. Someone mentioned that the cards from OWC Atlas will stop that from happening but I’m not so sure as I have no experience with them.
I haven't seen any thermal comparisons of the OWC's Atlas's cards but based on SSD Review's comparisons, the Delkin Blacks are the coolest running CFE Type B cards they've tested, at least as of a few years ago.

The warning is just a warning. Shoot more and worry less.
CFE cards have thermal thresholds that result in throttling when breached, so the fact the camera is relaying a thermal warning from the card indicates shooting performance may be affected.
July/August is often 105 degrees when I'm shooting and get the hot card warning occasionally. I just keep going and everything is fine, though I'm not taking huge amounts. I think it's just more of a heads up and also if you remove the card to be extra careful.
As somebody who lives in Texas and shoots Delkin black cards, I guarantee you I have more experience here than you do.

I certainly will not claim it doesn't/can't impact shooting performance.
Though I can say given my use cases, I see zero differences when the warning is active.

Yep, the warning only indicates it may impact performance. Whether or not it does depends on the warning thresholds/tiers the specific card reports, the stages of thermal throttling the card implements, and the workload applied to the card relative to that throttling staging. The takeaway is that warnings shouldn't be summarily dismissed - you can still safely operate the card but with the proviso that performance may be impacted, ie something to keep an eye on.

My in-the-field experience over years in 110+ degree temps in direct sun rattling off max speed burts for hours on ends beats you sitting in your basement as usual.
OP, make sure to bump the warning threshold to high and you'll see it pop up less.

Your field experience and others' is certainly helpful but the fact your shooting situations weren't affected is not evidence the card isn't throttling, nor that the card wouldn't materially throttle in other situations and workload demands. The NVMe warning thresholds in cards are literally tied to throttling behavior/warnings, so the fact the warning is being reported is prima facie evidence that throttling may be occurring.
My basement is being redone - I'm typing on the patio today.
