Waterblock Shootout

A Closer Look

A Closer Look
XSPC Delta V3
There are a few noticeable changes about the XSPC Delta V3 Acetal waterblock that are worthy of further discussion. Firstly, gone is the machined brass all metal top with chrome finish, and it has been replaced with an Acetal one. The Acetal top is machined to accommodate G1/4 barb holes. The 'X' for XSPC is still present on the top though, as on the other two versions of the block.
Secondly, the copper base is no longer press fitted to the top, but instead four screws have been implemented to make cleaning of the waterblock easier. The copper base also has a really nice mirror finish to it.

With the XSPC Delta V3 Acetal waterblock pulled apart we can see the pins inside. According to XSPC, the pin count has been increased from around a 1000 to just over 1600 pins. Looking at the underside of the Acetal top we can see that there is a solid piece of Acetal that has been left in the centre. The G1/4 barb hole on the underside of the Acetal top is also machined slightly larger than where the bottom of the barb sits. This is probably more than likely to allow greater coverage of the cooling pins with the coolant.
Swiftech Apogee GTZ
The Swiftech Apogee GTZ is an impressive looking beast. Featuring a screw-on backplate, this will ensure that you're able to screw the block down nice and firmly against the surface of your processors IHS. Like the XSPC Delta V3 water block, the Swiftech Apogee GTZ features an Acetal top with 'GTZ' machined into it.

The copper base of the Swiftech Apogee GTZ is very well lapped, and has an amazing mirror finish. The copper base is attached to the Acetal top via four 3/32" hex head screws. Once the screws are undone, the Swiftech Apogee GTZ can be seen in its entirety. The copper base features micro-channels to draw heat away from the base and then into the coolant. The micro-channels should allow this waterblock to be extremely efficient when it comes to flow performance.
The underside of the Acetal top features an elongated inlet which should provide additional dispersion of coolant over the micro-channels on the base. The inlet on the underside of the Swiftech Apogee GTZ features a slightly larger surfacing than the barb size, but yet the remainder of the inlet is a little smaller. This feature should force coolant to disperse over a greater surface area of the copper base.
Aqua Computer Cuplex HD
Like I said on the previous page, this block epitomises art, Instead of including an additional hold-down plate like the XSPC Delta V3, the Cuplex HD's hold-down plate is part of the waterblock itself. Unfortunately, it doesn't provide the universal compatability of the XSPC Delta V3; instead it is only compatible with Intel Socket 478 and LGA775 platforms. The top of the Cuplex HD is fitted out with G1/4 holes into an Acetal block, and according to the company they are not planning on releasing the waterblock in any other hole-size format. At least in the short term
The Aqua Computer Cuplex HD waterblock's copper base is very well lapped and free of any visible marks. The mirror finish is quite exceptional. Unfortunately, the sample I received had some deep scuff marks on one leg of the hold-down plate, although this will not affect performance of the waterblock in any way.

The Aqua Computer Cuplex HD waterblock is probably the closest of the three to have utilised an impingement style of cooling.

With the release of some new waterblocks on the scene, we thought it was time to have a little shootout between the three new kids on the block, and a couple of the oldies.


Check out the review hereQuote

Sweeeeeeeeeet review PV, really love the shootouts Quote

Ive been waiting for this!!! Great review! I think I am sold on the GTZ! The mounting system looks great and it performs dam well

Thanks PV for making my day!Quote

Great review mate. Shame the Cuplex didn't do better as I really like the look of it too. Can't have it all I guess Quote

09-10-2008, 11:33:10

Yeah, It certainly looks the best...

The D-tek didnt do too well at all though Quote

Remember that was the V1 tho.Quote

Just ordered a few Aqua-computer parts.. couplex XT DI cooler.. let's hope it performs better ..not that it's a big deal but ..


09-10-2008, 13:00:31

I have ordered the Swiftech from WCUK and its been dispatched already Quote

Interesting that Aqua Computer decided to stick to a very restrictive design... with the likes of D-TEK, Danger Den, Swiftech and XSPC all focusing on high flow rates and low pressure drop they've left themselves in the same camp as EK, a very formidable opponent.Quote

Great review PV...

One question however. Why didn't the GTZ get the best in class award as the Supreme currently holds it. By the results you got, it was stomped!Quote

09-10-2008, 15:27:44

Top job as always guys!

Bit suprised to see that the GTZ and Delta are so close to each other so congrats to XSPC for making an affordable yet high performing block.

Quick note about the 775 brackets that got mentioned for the Delta, we should have them available for retail in approx. 10 days time.

We've already made the proto and tried it, just waiting to get them back from being powder coated now.

Great review m8.Quote

Great review Peevs

Isn't the AC blocvk designed to run with their own pumps and a whole lower-flow system. I understand they have made some concessions to those wanting high-flow systems but afaik they are primarily designed to run in low-flow, restrictive systems?

Either was a beautiful block and gotta love XSPC's VFM as usual Quote

13-10-2008, 04:47:44

Hmm well, I hope their external kit (Aquaduct 360 XT MK2) can run all my blocks, or I'll have to buy an extra aquastream pump.. (going to cool: cpu, nb+sb, voltageregulators (x2) and 2x9800gx2 cards)... Sigh, I should have gone for the internal kit from the start, but I werent really in the mood for swapping case with my old pc (which is allready modded for watercooling).... Bwah.. we'll see


14-10-2008, 12:32:00

didnt search very hard for the cheapest places tho did you Quote

17-10-2008, 04:44:52

just a quicky, Swiftech have changed their packaging for the GTZ to the blister back similar to how the Apogee G T and GTX came.

Good review though PVQuote

Oooh nice. Thanks Ayd Quote
