Gigabyte has announced the GeForce GTX 980 WATERFORCE water-cooled graphics card, and this one is ready to go out of the box thanks to an integrated closed-loop liquid cooler.
In addition to full liquid cooling, the card - model GV-N980WAOC-4GD - also features "GPU Gauntlet Sorting", meaning that each card has a binned GTX 980 core for better overclocking performance.
"The GTX 980 WATERFORCE is fitted with only the top-performing GPU core through the very own GPU Gauntlet Sorting technology that guarantees superior overclocking capabilities in terms of excellent power switching and thermal efficiency. Only the strongest processors survived can be qualified for the GTX 980 WATERFORCE, which can fulfill both gaming enthusiasts’ and overclockers’ expectations with greater overclocking headroom, and higher, stable boost clocks under heavy load."
The cooling system for the GTX 980 WATERFORCE begins with a full-coverage block that cools the GPU, RAM, power delivery, without the need for any additional fan for board components. The tubes carrying liquid to the radiator are 45 cm SFP, which Gigabyte says "effectively prevent...leak(s) and fare a lower coolant evaporation rate", and the system is connected to a 120 mm radiator.
Gigabyte says both the fan and the pump offer low noise output, and claim that this cooling system allows the GTX 980 WATERFORCE to "perform up to 38.8% cooler than the reference cooling" for cool and quiet gaming.
The WATERFORCE card also features two DVI outputs (reference is one dual-link output) in addition to the standard three DisplayPort 1.2 and single HDMI 2.0 outputs of a GTX 980.
Pricing and availability have not been announced.

AMD officially launched its R9 Nano graphics card last week, and aftermarket coolers are already starting to ship. German-based Aqua Computer is the first company to offer a custom cooler for AMD’s pint-sized powerhouse. The Kryographics R9 Nano is a full cover water block that takes the already tiny card to a single slot design.
The Kryographics R9 Nano cooler is a machined copper block that covers the entire PCB and is paired to the VRMs using thermal pads and the GPU (and HBM) using thermal compound. The single slot cooler comes in two options including a see-through translucent ruby colored acrylic glass variant and a version with a brushed stainless steel top cover. In all cases, the block itself is all copper with microchannels over the GPU portion.
The cooler uses standard G1/4 threading on the ports and is compatible with CrossFire multi-GPU watercooled setups by removing the terminating screws and adding ports on the oppposite side of the card..
According to Aqua Computer, the Kryographics cooler was able to keep the R9 Nano GPU under 35 degrees C throughout their testing using Furmark. It will be interesting to see if the new cooler would allow the chips to maintain higher clockspeeds, especially with the power target maxed out in CCC. The need to fit a radiator, pump, and tubing in the case does while still needing to use a Nano (in lieu of a Fury X) makes this a niche within a niche product, but I’m sure some enthusiast will find a use for it!
The Kryographics R9 Nano is available for purchase now (though there is currently a shipping delay of 10 days). The base version without the see-through window has an MSRP of 89.90 EUR while the Kryographics Acrylic Glass Edition has a slight premium at 99.90 EUR. (At the time of writing, that pricing works out to about $102 and $113 USD respectively.)

The Razor GTX680 water block was among the first in the XSPC full cover line of blocks. The previous generation of XSPC water blocks offered cooling for the GPU as well as the memory and on-board VRMs, but did not offer the protection that a full card-sized block offers to the sensitive components integrated into the card's PCB. At an MSRP of $99.99, the Razor GTX680 water block is a sound investment.

The Razor GTX680 block comes with a total of seven G1/4" ports - four on the inlet side (left) and three on the outlet side (right). XSPC included the following component with the block: XSPC thermal compound, dual blue LEDs, five steel port caps, paper washers and mounting screws, and TIM (thermal interface material) for use with the on board memory and VRM chips.
