These 970 Evo will consume 6W or so under load, that might be in the ballpark of many DIMMs, but so what that's irrelevant too. Computers are designed with very specific cooling to handle that constant DIMM heat load. A small fan in a shroud in a PCIE slot with 2 x 6W, that may add up. And you are defeating that shroud as a heatshink design, not a good idea at all. These things are pretty easy to thermal model today, lots of consultants out there that will do that for even small manufacturers, so follow the manufacturers advice.
I don't understand your statement of "And you are defeating that shroud as a heatshink design, not a good idea at all." - please explain. And what is this 'small fan in a shroud in a pcie slot' you speak of?

And I believe the Mac cheesegrater's cooling is actually designed for way more cooling than you think. How about putting cards in every slot in the card cage? Surely that raises the heat load?
