the case as no cut out so looking for a thin one.

Thermal pads or thermal putty
Between the nvme and motherboard tray?
Assuming there's not a cut out in the motherboard tray

indeed you do

If that works
Basically using the motherboard tray/case
As a heatsink should be reasonably effective hopefully
It's a large surface area
Just not concentrated in such a small area
As a heatsink with fins would be

I really don't get these boards with M2 slots on the rear. It's bad enough trying to cool a M2 drive that sits under the GPU but putting a slot on the rear of the motherboard where there is no airflow is crazy. Hopefully the gap between the drive and motherboard tray isn't too big to use a thermal pad or putty but it's still probably going to be a very warm drive. No chance with a Gen 5 drive, 50/50 with a Gen 4 drive but it should work with a Gen 3 drive.

Gen 3 drives also get pretty toasty at the back of the mobo
I used a sn750 there back in the day. Would not recommend if you can avoid it.

Mine at the time was the WD black sn750 pcie3. No heatsink. A thin heatsink may help but Ive never tested it

It’s an itx board. Tbf I’m happy it’s there but your it’s not the best design.

The drive is an older gen 4

Another possible option?
Use a nvme riser/extender cable
To position the drive somewhere better
Though not sure how long a riser cable you
Can get

this is not really an option for me, im going to test fit and see how much room there is for a pad i think thats the way to go really

I have used plenty of the lower end NVMe Gen4 drives on the rear of the board with no heatsinks and they were fine. Its only when you start getting up to the higher speed ones that they start to get toasty.
