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.Credit: IntelCredit: IntelAt 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.Credit: IntelCredit: IntelIt 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.
