Phoronixreports the driver should incorporate a mechanism to reduce the link width of PCIe Gen 6 devices. So, a Gen 6 x4 drive could reduce to x2 or x1 when the system detects excessively high temperatures. Thechangelogindicates changes to link width in this way is not possible with Gen 5 devices.

The driver itself is actually a good idea. I like the idea of dynamic throttling under the right circumstances, but that we need it at all is what’s concerning. A fast Gen 5 drive that can hit 14 GB/s can easily throttle if not cooled appropriately. I shudder to think what kind of cooling a top spec Gen 6 drive will require. Maybe we’ll see moreAIO’s with integrated M.2 cooling blocks.

For now, the driver is for Linux only, leaving questions about how or if such a driver could make it to the Windows ecosystem. It shouldn’t be too hard to develop. If Gen 6 devices really are nuclear, the SSD industry, Intel, AMD, Microsoft and laptop manufacturers should be able to put their heads together and make something like this work.

I’d like to see a move away from typical x4 drives to more x2 or x1 drives. A Gen 6 x1 drive will still be able to transfer at up to 7GB/s, the same as a Gen 4 x4 drive now. Most of us will never need a Gen 6 x4 drive that can transfer 28 GB/s sequentially, and if you do, you will need two Gen 6 x4 slots anyway, which most consumer motherboards will certainly lack.

My gripes aside, It is good to see dynamic throttling come not just to SSDs, but hopefully all PCIe devices. As long as it works without any issue of course! A few watts saved here or there will all add up. Lower temperatures will always be welcome. And with that, hopefully annoying little fans can be banished too.
