Waterblock Shootout


I must confess that there has been a number of surprises here today during the review of the XSPC Delta V3, Swiftech Apogee GTZ and the AC Cuplex HD waterblocks. Let's see how they faired as a whole.
Aqua Computer Cuplex HD Aqua Computer Cuplex HD
The AC Cuplex HD is an amazingly well crafted waterblock, and one that would compliment a high-end rig perfectly. The quality and craftmanship is really evident here. Admittedly though, the AC Cuplex HD waterblock is very restrictive and would be better suited to either a CPU only loop, or with a high-flow pump. If you were to use the AC Cuplex HD in a water-cooled SLI setup, you may find the flow less than adequate. However, to the AC Cuplex HD's credit it exhibits very little pressure drop.
The best price I could find for the Aqua Computer Cuplex HD waterblock was from WaterCooling UK, and it comes in at £39.99 inc. VAT
The Good
+ Amazing build quality and attention to detail
+ Easy to disassemble and clean
+ Looks
+ Low profile
The Mediocre
* AMD users miss out due to non-compatibility
* G1/4 only
The Bad
- Restrictive

Swiftech Apogee GTZ Swiftech Apogee GTZ
The Swiftech Apogee GTZ was my first foray into Swiftech waterblocks since the Swiftech Storm G4. The build quality is typical Swiftech - function and form wrapped up in a smart looking package. The Swiftech Apogee performed really well today and managed to just edge out the XSPC Delta V3 to take the gold. The Swiftech Apogee facilitates very respectable flow and at the same time experiences very little pressure drop. The Apogee GTZ would be an excellent addition to any water-cooled setup and would work really well in a multi-block loop.
The best price I could find for the Swiftech Apogee GTZ was again at WaterCooling UK and it comes in slightly dearer than the Aqua Computer Cuplex HD at £43.99 inc. VAT
The Good
+ Smart looks
+ Low profile
+ Performance
+ Includes a backplate so you can screw the block right down
+ Universal compatibility
The Mediocre
* Price is a little dearer than both the Aqua Computer Cuplex HD and the XSPC Delta V3
* Universal compatibility requires the purchase of additional mounting hardware.
The Bad
- Nothing to report

XSPC Delta V3 Acetal XSPC Delta V3
The XSPC was the biggest surprise of the bunch as far as I'm concerned. The XSPC comes with so much potential cooling performance for such a cheap price - currently available from WaterCooling UK at £34.99 inc. VAT. The XSPC Delta V3, as with previous versions, provides universal compatibility for both AMD and Intel users. However, the mounting plate may cause some compatibility issues with certain chipset cooling solutions. Rob @ WaterCooling UK has told me that they have some alternative mounting plates currently being made to address this issue.
The Acetal top of the XSPC Delta V3 makes a nice change from the chrome finish on earlier versions of this waterblock, and the screw-apart base also makes cleaning very easy. It certainly looks like XSPC have done their homework in addressing the short comings of previous versions of the Delta waterblock range, and it's finally paying dividends.
The Good
+ Price
+ Performance
+ Looks - the Acetal top increases the visual appeal
+ Universal compatibility
The Mediocre
* Universal backplate may cause compatibility issues with some chipset cooling solutions
The Bad
- Nothing to report.

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

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

09-10-2008, 13:16:13

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
