So, you say you're using a D15, but there is no D15 specifically designed for sTR4. The only Noctua coolers that do that are the U14S TR4 and its offspring (U12S, U9, etc.).
It could be possible that the edges of the chiplets are overheating due to having little to no cooler contact, causing system shutdown. Might be something to look into.
