Wow, those looks like the same as the 1366 model just modified for the narrow ILM 2011-v3 takes.I finally received the heatsink I ordered. I choose a passively cooled (via air shroud) Supermicro heatsink with narrow ILM 2011-v3 mounting. This was the only compatible one: SUPERMICRO SNK-P0048PS 2U Passive CPU Heatsink for LGA2011 - Newegg.com
In my first post, parts list - I linked to Supermicro's heatsink parts list if anyone needs it.
It is much larger in person. Waiting for my new lens to come in and I'll take more in case motherboard/heastink photos.
I have a handful of those for 1366 if anyone needs any, lol!!
