Question Small SSD Heatsinks

Mini ITX motherboards have one SSD slot at the back of the board. I think the NR200 has about some milimeters of gap between the back of the motherboard and the right side panel (I don't know how big). I THINK the heatsink of the SN850X will fit.

Is there any SSD heatsink thin enough to be placed there?
I am okay if the heatsink only prolongs the time it takes for the SSD to reach its throttling temperature, as long as the price isn't too expensive.

Thank you in advance.
 
A cursory glance on Amazon tells me there's heat sinks as short as 3mm, and there's basically copper heat spreaders. Depending on the actual thickness, it might be good to get a copper heat spreader and a thermal pad so it makes a connection to the case and starts dumping heat into that.

Interesting. I thought the side panel was plastic, but it turned out to be steel, which is perfect for the heatsink's surface area.

Now the question probably will just be, how wide is the gap.
