Anyone who read our Titan X (Pascal) review will know just how power- and thermally-limited Nvidia's new beast is. With these limits lifted via third-party software, you can overclock it to an impressive degree, but the cooler becomes much noisier and power consumption spikes as well. Water-cooling can't address this latter point, but it sure can do something about the former. As such, we jumped at the chance to get a water block in and see what could really be achieved.

The water block we got in comes from Aqua Computer, and is the Kryographics Pascal for Nvidia Titan X (Acrylic Glass Edition). It retails for 100 Euros or about £85, at least when it's in stock. First impressions are certainly positive: it weighs in at over 1kg, and the build quality is top notch. The bulk of the weight of course comes from the thick copper base, although a stainless steel frame and the acrylic glass covering complete the block.

On the underside, you can see the polished contact plates for the GPU and twelve memory chips, while on the right side there's an additional contact area for the VRMs. The coolant enters the block and immediately passes over much of the memory before entering the jet-plate that takes care of the GPU. After this, it splits into three different channels (which helps to boost surface area) to take care of the remaining memory and power components.

The Delrin connection terminal has G 1/4 inlet and outlet fittings on both sides, so it should fit easily and neatly into a loop regardless of where the other connections are positioned. A pair of plugs are provided to block out the unused connections. The terminal can be replaced with other kits specifically for SLI setups, and the water block is indented enough to make way for the new high-bandwidth SLI bridges, although we're only testing a single card setup here.

Relatively speaking, the Titan X is a pretty difficult card to disassemble, if only for the sheer number of screws needed. The backplate has tiny Philips 1mm screws that need removing, and comes off in two parts. After this, a normal Philips screwdriver is needed as well as a 4mm hex nut screwdriver to release the Titan X cooler from the now exposed rear of the PCB. Our early water block sample was not supplied with one of these, but we're told that retail ones will be.

Eventually, you'll be able to pry the cooler off – remember to disconnect the illumination and fan cables first, however. After this you'll be left with a card with thermal gunk and padding all over it, and this all needs to be removed and the surfaces cleaned as best as possible.

Thermal paste is needed for the GPU and twelve memory chips and you'll need to purchase this separately as it isn't supplied, sadly. That said, we assume most people interested in water-cooling won't be phased by this and probably have a few spare tubes anyway. What you do get is a thermally conductive pad, which needs to be chopped up and applied to the MOSFET area, as shown – it's a shame a single pad large enough to cover the whole section here isn't supplied.

Finally, you're now ready to secure the water block, which involves securing 11 screws. A few areas that are directly cooled by the standard Titan X cooler, most notably the capacitors in between the chokes and memory chips, are not physically connected to the water block – hopefully this doesn't affect overclocking.

Aqua Computer does have backplate options for its Titan X water-coolers, and while it was kind enough to send us one we didn't have time to test with it as our time with the card was limited. Still, the water block is of course the most important component, so let's see what it can do.
