Hello!

I failed finding information on the Dell U.2 enablement kit P31H2 so I am asking here.

Does this card absolutely have to be installed in an x16 PCIe Slot or will it work at a x8 as well (with reduced max. speed)?

What does the card do exactly? Splitting 16 lanes into 4x4 with bifurcation should as far as I know not require a big heat sink like that.

Any advice is appreciated! Thanks in advance
