PCIe 5.0 SSD: Cooler Sold Separately

ASRock Unveils Blazing M.2 PCIe Gen 5 SSD Cooler With Active Fan Heatsink, Compatible With Z790, X670E & B650 Motherboards

ASRock has revealed its Blazing M.2 PCIe Gen 5 SSD [cooler] which is an active fan heatsink for X670E, Z790 & B650 motherboards.

ASRock has developed five styles for the new SSD cooling system, and it is stated that the airflow, measured in cubic feet per minute (cfm), will be 4.92. The new Blazing M.2 PCIe Gen 5 SSD cooling fan attachments will be compatible with X670E, B650 and B650E, and Z790 motherboards, and the company has provided a list of compatible models and which type of cooler variant will work with each.

Earlier this year, in March, Phison reminded manufacturers and users of the elevated temperatures that PCIe Gen 5 M.2 NVMe SSD devices would produce. Not only would the new PCIe SSDs offer speeds topping 14GBps, but Phison reported that the M.2 SSD controller limits had been factory set to 125°C. Phison explained that as the drive is filled with data, the temperatures increase. However, the NAND flash memory, which can only accept up to 80°C, will cause the SSD to go into a critical state and shut down the system, causing losses of information and depreciation of the system.

    Currently, 30% of the heat is dissipated via the M.2 connector and 70% via the M.2 screw.

    Apparently they are actually doing that, by going to a new M.2 25110 size with more surface area and a wider connector:

    Gigabyte said at Computex 2022 that it believes many of the future PCIe 5.0 SSDs will be considerably larger than the M.2 SSDs that are commonplace right now. This is because, according to Gigabyte, many PCIe 5.0 SSDs will adopt the M.2 25110 SSD form factor. Such SSDs are 22mm wide and 110mm long, and that size could create incompatibility with today’s motherboards.

    The majority of the best SSDs currently available use the M.2 2280 form factor. As mentioned, there’s a marked difference in size, seeing as the M.2 2280 form factor SSDs are 22mm wide and 80mm long. This means that most of the motherboards out right now would not be able to support these larger M.2 25110 SSDs, which could make their adoption a lot trickier.

    I didn't know about M.2 25110 until just now, but it's in some of the new AM5 motherboards:

    Some AMD X670/X670E mainboards will also come with an M.2-25110 slot(s) for upcoming high-performance SSDs with a PCIe 5.0 x4 interface that requires more sophisticated cooling.

    I think I heard somewhere that M.2 will need to go away entirely in favor of some new design. Kind of like Dell replacing SO-DIMM with CAMM in part because of thermal performance [pcworld.com].

    If that's not the case, maybe they can still double M.2 speeds with PCIe 6.0 and just rely on active cooling to handle it. And then for PCIe 7.0, just slash the lane count in half as the previous article suggests, so no speed increase but systems could support more drives or use the lanes saved for other I/O.
