First Look: Corsair's new DHX+

First Look: Corsair's new DHX+

It's got screws n everything

Corsair dropped off some of its latest Dominator 2, or "DHX+" as they will be officially know modules to the bit-tech offices and we couldn't help but share. Having not updated its DHX technology for a few years now these modules are the first major update Corsair has launched while other competitors have caught up with more elaborate solutions. Technically, DHX was great, but aesthetically we feel it's lost its "special" since Corsair used it everywhere - this is where the Dominator 2s should levy that unique appeal again.

In some respects the modules follow on from the original DHX design - the PCB is taller than most and is still cooled in addition to the memory chips, however instead of the two fin approach, Corsair has modified the design into one thick-sink, then bolted on a line of chunky fins to the top.

The heatsinks appear to be glued to the PCB at the top, yet thermal-pads adhere it to the memory below. Unscrewing the Dominator 2 fins at the top just unlocks it from the two sinks on either side - the bar underneath provides a thread for the screws to bite. Corsair said that because of its ease of removal and direct connection to the heatsinks on both sides - this allows future mods or end user invention.

Corsair also told us that "[the] DHX+ is essentially equivalent to DHX in terms of passive cooling performance", although we'll be sure to test this for ourselves. DHX+ will also only be available on Dominator modules, DDR3 to start with and possibly DDR2 later on. The Original DHX will also be slowly phased out in favour of DHX+, although both will co-exist for a while, however there will be no "Silver DHX+" for performance-value modules like there is with current DHX parts - only the Dominators will get the premium coolers again.

In all, the DHX+ is not a "Wow, I've never seen that before" change like some crazier heatpipes or watercooling others try, but it's an breath of fresh air and an evolutionary development none the less. We like the idea of mod-ability, and hope that some more interesting user solutions evolve in time.

Do you like the Dominator 2 style? Do you think it'll perform well? What about the competition? Let us know in the forums!

looks like the old version has more surface area - shouldn't that mean the older version be better for cooling?

Like the more integrated look though

My thoughts exactly.

But these ones look like they can be removed... making easier to use 3rd party waterblocks.

When I tried to remove the heatsinks from my Dominator ram I accidentally pulled the ram chips off with it.
Luckily Corsair ended up sponsoring me with naked RAM instead.

I'd toss the removable top parts in a bath of lye to strip the anodizing off them and then have them chromed...

I think that's the idea. The cooling performance should be about equal because the mass of aluminium is greater and low voltage DDR3 for Core i7s doesn't produce that much heat tbh

"it's got screws n everything"

rofl, absolutely brilliant!

oh yeh, nice idea on the ram bla bla bla

Heat discipation is imparative but with tri channel memory on the new i7 chips, realestate might be an issue, the shear bulk of the overhead heat sink or liquid cooling gear clusters the ram ports. When passively cooled it makes it even worse when multiple sets are used, Im sure more work can be done on slimmer designs. lets hope corsair lives up to their performance reputation in the new race for "DDR3".

i can see this working with one block effectively cooling 2 or more ram sticks. Might need a custom cooler though. Imagine removing the tops and slapping on a water block that is not as restrictive as those tiny ones we have today.
*goes off to figure out how

@Spaceraver - I was thinking the same thing actually - shouldn't be too long now before someone comes out with a cooler

I think Corsair really tought about this one... Since most of the airflow is coming from the right, this is the least restrcitive for the airflow, and thus the most effective. I like the look of the old ones better though...

Airflow comes from the side-panel inwards too, and Dominator 2 kits come with an updated top-down cooling fan with 2x60mm fans.
