Alphacool HDX – M.2 SSDM01
The first company to offer a third-party M.2 heatsink, Alphacool’s fairly simple example comprises just two aluminium plates with no fins. As a result, its height is under 3mm including its thermal pad, and it also cools the underside of the SSD. Installation is fiddly, though, with four metal clips installed in each corner requiring a large amount of force to fit compared with the EK heatsink.
The lack of fins hurt it in testing too, with the delta T in our cramped M.2 port coming up 10°C warmer than the best result at 41°C; in the open port, it managed 33°C – both are the worst results on test. It’s worth a look if you need a short heatsink, but otherwise, there are plenty of better all-round alternatives.
