is this compatible with the d15s?

The NM-AM4-UxS kit is compatible with the NH-U14S, NH-U12S and NH-U9S only. Others use the NM-AM4 kit. The NH-D15S with AM4 mounting kit has been included since 2019, only older coolers require upgrade kit - and I believe you can still obtain the NM-AM4 mounting kit free of charge (via a form on Noctua's website). A proof of purchase (electronic version, photo or scan of the invoice) of both a Noctua CPU cooler and either a socket AM4 mainboard or socket AM4 CPU are required.
