Server vendors managed cooling just fine for years with 80 pin SCA
connectors.  Hard drives are also harder to cool, as they are a solid
block, filling the space, unlike a card of chips.

I'm not saying the problems are the same, but I am saying that a
backplane making cooling "hard" is not a good excuse, especially when
the small empty chassis costs $10K+.
