ASUS has taken the wraps off of a new dual GPU graphics card that comes equipped with a sealed loop liquid cooler to keep the two overclocked 7970 GHz Edition GPUs frosty. The new ROG ARES II is a limited edition card that pairs the ARES II GPU with an Asetek-based cooler and rounds out the top-end of the company’s Republic of Gamers lineup.
The card itself features two AMD Radeon 7970 GHz Edition GPUs clocked at 1050 MHz base and 1100 MHz boost, 6GB of GDDR5 memory clocked at 1650 MHz, and ASUS’ DIGI+ 20-phase VRM with “Super Alloy Power” hardware. The ROG ARES II has a 500W TDP and uses three 8-pin PCI-E power connectors. The card measures 11.8” x 5.5” x1.8,” not including the radiator.
The ROG ARES II includes one DVI-I, one DVI-D, and four DisplayPort video outputs. ASUS is also packing a DVI to HDMI adapter in the box.
The sealed loop water cooler is where the card sets itself apart, however. Based on an Asetek design, the ARES II water cooler features a 120mm radiator, and two CPU-style water blocks over each 7970 GHz Edition GPU. The loop runs from the radiator and through both water blocks before returning to the radiator which is paired with two 120mm fans. Curiously, the water cooler did not result in a single-slot design. Rather, the ARES II card has a somewhat-bulky two slot profile. According to ASUS, the water cooled card will run up to 31 degrees Celsius cooler than the reference NVIDIA GTX 690 graphics card while being as much as 13% faster (though ASUS does not specifically name the games/benchmarks).
ASUS has not released any pricing or availability information, but you can expect it to rival the price of PowerColor’s Devil 13 thanks to the sealed loop water cooler and ARES II hardware. Currently, ASUS is planning on producing a mere 1,000 liquid cooled ARES II cards, so be prepared to be fast on the mouse click upon release.
I would have liked to see a water cooler that was a bit more customized to the card. In particular, I think ASUS should have used a single water block that covered both GPUS and the VRM area, which would have allowed ASUS to get rid of the fan on the card itself entirely. Nevertheless, the ARES II will be extremely fast, and hopefully run nice and cool even when overclocked. I’m interested in seeing a head-to-head between the ARES II and PowerColor Devil 13.

According to Xbit Labs, AMD is considering switching out the usual air cooler (HSF) for a sealed loop liquid cooling solution (LCS) for its high end FX Processors. Specifically, AMD wants to pair their highest end eight core processor (and possibly the next highest end eight core chip) with the sealed loop liquid cooling solution. This information, they believe, comes from a “source with knowledge of the company’s plans.”
If you are not familiar with the sealed loop water coolers, PC Perspective reviewed the Corsair H70 processor cooler last year and it is a good example. Sealed loop water coolers are similar to the large DIY water cooling loops comprised of a large radiator, copper CPU block, pump, and reservoir all connected in a loop by tubing; however, they usually have smaller radiators and pumps as well as coolant that cannot be refilled (and should not have to be). This coolant carries heat away from the processor to be dissipated through a radiator. Corsair in particular has heavily invested in this once very niche product with it’s H series of coolers.
Traditionally, both Intel and AMD have been content in pairing their chips with mid-range but cheap air coolers that did a decent job of keeping the processors within their thermal limits at stock speeds. Enthusiasts, and especially those interested in overclocking, have generally ditched the included cooler in favor of a more powerful and/or quieter aftermarket cooler. Needless to say, including a cooler, especially with high end chips that will likely go to enthusiasts, that’s never even used only serves to add additional unnecessary cost for both consumers and the manufacturer. Thus, this move to bundle a more powerful sealed loop water cooler with its high end chips may be an attempt by AMD to futher appeal to enthusiasts and keep with their traditional image of being friendly to overclockers and hardware enthusiasts. Having and using a water cooler that is supported by the chip maker certainly doesn’t hurt, especially if it ever came down to warranty and RMA situations. On the other hand, enthusiasts can be very picky about which cooler to use in their systems; therefore, bundling a cooler that is sure to add even more extra cost to the package may not be the right move for AMD. At best, consumers are likely to see an extra $50 or so added to the sure to be pricey highest end eight core chips.
Their idea, if true, surely has merit, but is it wise? Let us know your thoughts in the comments below!
