This week Alphacool announced the availability of their new M.2 SSD Coolers, the HDX-2 and HDX-3. Some may recall the original HDX M.2 cooler was a simple, passive, clip on heatsink for M.2 SSDs, and was designed to help prevent thermal throttling which has a tendency to plague synthetic test results on some M.2 based drives. With the advent of the HDX-2 and HDX-3, they have moved beyond the simple clip cooler and to using a PCIe x4 card. This design change allowed a full sized heatsink to be mounted on it giving more surface area to cool the attached M.2 device. The HDX-3 takes the HDX-2 and its passive setup a step further and uses a waterblock instead of the large heatsink to remove the heat created from these SSDs.

 

The dimensions both the of HDX-2 come in at 100 x 81.5 x 20 mm with the HDX-3 being slightly taller at 120 mm while sharing the same width and height. According to Alphacool, the included 4x PCIe card allows a maximum bandwidth of around 3900 MB/s. Existing M.2 drives on the market will not be able to saturate it. Though it is double sided, both M.2 coolers hold one M.2 based device. Contact from the M.2 device to the heatsink is provided by included thermal pads. These thermals pads cover both single and double sided M.2 drives. The HDX-2 and HDX-3 both support up to one 80mm M.2 SSD. Both devices connect to the PCIe slot and mount to the case for a stable platform.

Technical Data HDX-2 HDX-3
Dimensions (LxWxH) 100 x 81.5 x 20 mm 120 x 81.5 x 20 mm
Material Aluminum Copper, Acetal
Threads N/A 2x G 1/4"
PCIe Form Factor PCIe 3.0 x4
Compatibility M.2 2280 PCIe SSDs
Max. Bandwidth PCIe Card 3938 MB/s

The HDX-2 uses large aluminum heatsinks on both sides of the included PCIe card easily covering the M.2 drive it aims to cool. The heatsinks are black with αCOOL and HDX-2 stenciled on it in white as well as having cooling fins to increase cooling area - the heatsinks cover the entire PCB of the PCIe card. The drive is mounted to the PCB, thermal pads applied to the drive, then mount the heatsink to the board. 

The HDX-3 block is made of nickel-plated copper with the top made from a single piece of acetal. The block mounts to one side of the PCIe card leaving the other side open. Alphacool says water flows over the entire SSD to help keep things cool. The water enters and exits the block at the opposite end to the PCIe connector using standard G ¼” a threads. 

Pricing and availability were not listed in the press release.

    When will they give us what we really want: aftermarket RGB waterblocks for routers and modems Reply

    My K56flex data/fax modem agrees 100% with the idea of RGB water cooling. I also request that any buttons on the waterblock (and there should be at least 6 of them for the sake of looking cool) are backlit and feature Cherry MX switches. Power for the backlighting should flow through a 58-phase VRM and I will accept nothing less than solid caps. That'll make my modem rock the telephone line like a boss. Reply

    V.92 is better! I bet you're using a softmodem anyway!

    Now, onto the important question: If you watercool your SSD, how many extra megahertz can you squeeze out of the controller cores??

    I resigned my office-job and now I am getting paid 85 bucks hourly. How? I work over internet! My old work was making me miserable, so I was forced to try something different, two years after...I can say my life is changed-completely for the better!

    this is what i do.... http://cutt.us/SL0Hi

    Don't forget heatsink should be attached with high quality indium solder AMD style. Reply

    I used to put my tea on my old V.90 modem in order to keep the tea warm. Does that count as liquid cooled? Reply

    I need water cooler setup for my blu-ray reader/burner. Reply

    "2x G 1/14"

    Should be "2x G 1/4"

    Well that certainly makes getting an SSD out of your computer a lot more difficult. Reply
