Will these be on the case? Didn't see mention of that.

Personally, have the same motherboard, most likely hotter gpu (tahiti le) and atx midi case with 3 12mm fans in push pull configuration and it doesn't seem to gather that much heat running couple days straight as a miner. But each time I hit the miner, I'm cranking the case blades on full throttle. And those are pretty capable fans. So gotta take care of general cooling, or things might get cooked on longer run.
