There certainly won't be (and neither will active southbridge cooling). But at least you'll get PCIe3 between the CPU and the chipset.
Why do people think the chipset is Linked over PCI-E 2.0 ? There doesn't exist a AM4 Chipset that Links over PCI-E 2.0 they all (except X570) link over PCI-E 3.0
The lanes they Spit out are PCI-E 2.0
for B550 we know the lanes it's gonna's spit out will be PCI-E 3.0, so i hope the it will link over PCI-E 4.0 (and that also would make the most sence)
