Founder Edition cards do NOT have very good cooling - I would strongly recommend AGAINST them for mining usage.
In a closed case where air flow is managed front-to-back they actually have great cooling and are far superior to any aftermarket cooled cards.
Not to mention, you can fit them in closer because they are a 2-slot card/
Do this with aftermarket cards...
I would never do this with any cards. I just cannot understand this approach... you have money for 10x ti and You cannot afford to use some more space?
Don't tell me that those fe in the picture are properly cooled...
Of course they're properly cooled, and I'd bet they're running cooler than most peoples open air rigs, because they are in a data center that has AC, and are in a chassis that has been engineered with cooling that can handle the airflow required by FE cards. No one's going to risk the cost of 10 x 1080 ti cards without proper cooling!
This is the way things are done in the enterprise deep learning arena, and companies like Supermicro sell setups for 10 x Tesla cards, or consumer 1080 ti's work just fine:)
