It has been known for a while that some M.2 PCIe SSDs, including the popular Samsung 950 Pro SSD, have problems with throttling, which is easily fixed with some heatspreaders.
In order to fix these throttling problems, MSI will have a neat new feature that will probably be included on some of high-end Intel 200-series motherboards, scheduled to launch at CES 2017 show in January.
Spotted by Techpowerup.com, the M.2 Shield, as MSI decided to name it, is a thin heatspreader that clamps on top of the M.2-2280 slot and includes thermal padding on the inside that should transfer the heat from the SSD a bit more effectively, thus preventing throttling.
Unfortunately, there are still no details about actual motherboards that M.2 Shield will be included on, but a safe bet is that it will be a key part of some high-end Intel Z270 Express chipset that MSI will launch at CES 2017 in January next year.
