I did not; these will be going on an ASUS ROG Crosshair VIII Impact, the SO-DIMM.2 module they will occupy has built-in heat sinks...
Excellent. Definitely a cool board and I love that option. I only asked because I get a lot of questions about that drive and the optional heatsink, which frankly I think is ludicrous. No Gen4 drives (yet) myself but I'm running the X570 Aorus Master with three NVMe drives so I'm always curious.
