I don't use any m.2 cooling and I have trouble off and on with the drives. Possibly overheating?

Possibly. If you have no heatsink and just a bare M.2 drive but with a air cooled gpu sitting over the top of it and dumping its heat on the drive, I could see that you might be throttling because of high temps.
What does your motherboard sensors report for the temps?
Improve your case cooling to remove as much of the direct gpu heat exhaust dumping on the M.2 drive as you can with better airflow.
I kludged a heat sink below the m.2 drive on my NVIDIA Jetson Orin. It's a couple of small sheets of copper & Arctic Silver. There's no active cooling. The Orin is in a plastic case open on the sides. I haven't put a thermocouple on it to check the temps.
The Orin dev kit gets throttled all the time because it consumes more power than can be provided. IMHO a dumb-ass design decision.
Disappointed that the review never mentions either the warning temp or the throttling temp of the drives under review.
That data is available from the manufacturer or via the SMART details of the drive.
I took a quick audit of my various M.2 drives in my hosts and mainly found the critical warning temp around 86° C. for most of them.
The highest temp of the bare drives was listed at 77° C. in the review so unsure why the bare drives showed throttling.
I have an M.2 SSD on each of my three systems, and I'm not using any cooling method on any of them except for what's available on the motherboard. The 3950X & 5950X systems use the same motherboard, an ASUS Crosshair VIII.
My 3950X's M.2 SSD is presently running at 52 C with a 3080 GPU mounted directly over it, and the EPYC system's M.2 SSD is 'naked', like Keith's, and it runs in the high 40's C..
My 5950X's M.2 SSD is at the moment out of commission, but I remember it being a little hotter than I would like. I seem to recall it being in the mid 70's C range, but I will reapply a new thermal pad to it. I determined that the 3080 Ti GPU mounted directly on top of it was at least partly to blame.

So why does the Orin box power throttle? I see a coaxial barrel connector on it so it should just be a matter of providing a big enough power brick to feed it.
I don't have to worry about most of my drives in my hosts because I mostly use hybrid gpus so very little heat comes off the cards.
Only the Epyc hosts with one air-cooled 2080 Ti does any of that heat get forced down onto the motherboard.
Those hosts have dual 200mm fans blowing directly over the front of the motherboard and keep the drive temps down.
Saving grace on the Epyc boards is that the M.2 slots are perpendicular to the PCIE slots so only a small cross section of the M.2 drive has any gpu over the top of it exhausting heat.
All of the consumer boards on the other hand have all the M.2 slots are parallel to the PCIE slots and typically directly under any graphics card. Making the worst possible condition for any M.2 drive.

Interesting tid-bit about your EPYC motherboards. My EPYC is a Supermicro, not an ASRock, and it has an M.2 SSD which does run parallel to the PCIe slots in the same manner as most consumer motherboards do. Plus, I am running a 3090 Hybrid with doesn't dump anywhere near as much heat onto the M.2 SSD as my air cooled 3080 Ti does. I'm not sure ALL consumer motherboards have them running parallel, but I would say that most of them do.
Well saying ALL consumer motherboards have parallel M.2 orientation WAS a bit of an exaggeration. I've seen some boards with M.2 positions parallel to the memory slots and well away from the gpus.
IIRC (always a risk at my age...) the module can only handle 15W even though the supply is 45W. My understanding is that the extra power can be used for peripherals but not to supercharge the module.
