Alphacool Eisblock HDX-2 M.2 Cooler Review

If there is one thing we’ve learned about fast M.2 drives over the past year or so is that many of them get hot, very hot. Hot enough that that they will actually throttle and cause slower transfer speeds. We actually saw this in our review of the Kingston KC1000 M.2 drive. Obviously with many major drives (Samsung 950, anything Phison E7-based) having this issue something needed to be done, especially with so many of these drives out there. Well Alphacool has you covered with their Eisblock HDX line of M.2 coolers. There are actually 4 coolers in the line, but we will be mainly concentrating on the HDX-2, which is basically a PCI-Express 3.0 x4 card with an M.2 slot on it and a very large aluminum heatsink. This should definitely solve all of your M.2 throttling issues. Let’s take a look!

Special thanks to Alphacool for providing us with their Eisblock HDX-2 M.2 Cooler to review.

The Alphacool Eisblock HDX-2 comes in a simple box with the Alphacool logo on the front. Alphacool was nice enough to send us not only the HDX-2 but two of their HDX M.2 units, which are even smaller.

Opening the box up inside you will find the HDX-2 PCB, rear I/O over cover, the two pieces of the heatsink, thermal pads, installation hardware, and instructions.
