One Year Later: Intel Adds Heatsink To M.2 Optane 905P SSD

According to a recent product notice,Intel has added a heatsink to its Optane SSD 905P SSDs. The company first released the M.2 variant of its speedy Intel Optane 905P SSD a year ago, but a handful of concerns were raised about its ability to dissipate heat. This was only a natural response from the market because the other forms of Intel Optane 905P SSDs, such as the U.2-connected model and the more-common PCIe add-in-card, all had metal heatsinks. Yet the M.2 model lacked this particular feature when it came out roughly one year ago.

At the time, third-party cooler-maker EKWB introduced a passive heatsink that you could add on to the SSD to handle cooling. This was great, except that it cost an additional $20 plus shipping – and a lot of people weren’t amused by the apparent necessity for a third-party cooler, or the hassle of the extra effort. Consequently, we doubt many buyers opted to take this route.

It appears that Intel has listened to those concerns. It might have taken almost a year, but the chipmaker has come out with its own cooling solution for the 380GB Optane 905P M.2 SSD. It consists of an Optane-branded metal plate for each side of the unit.

    Any word on a hopefully adequately cooled PCIE 4.0 x4 Optane?

    My guess is that with Intel stating that they're going to jump to PCI-E gen 5 in 2021, they'll just skip 4.

    Intel provides pcie4 in Stratix 10 and Agilex FPGAs and has announced it in their Ice Lake Server chips for 2020. Its use is also documented for their eyeq5 chip.
