I've probably looked at more motherboards just today than I have in the past three combined. That's because every manufacturer has brand new Z790 motherboards ready to show off ahead of a yet unannounced Intel processor generation (that's the Raptor Lake refresh, by the way). But one thing I've noticed across nearly every board I've seen today, be it from ASRock, Gigabyte, or MSI, is that they all are fitted with seriously beefy coolers on their PCIe 5.0 NVMe slots.
Some of these coolers are included on the motherboard, and even these integrated designs are looking beefed up with the coming generation of SSDs. But take a look at some of the coolers included or available as extras for PCIe 5.0 drives and things get out of hand pretty quickly.
