Hybrid technology is not new in the auto industry, and it is referred to how a car is powered: a standard fuel engine aided by an electrical engine, or the other way around. But when we are talking about Hybrid cooling, then we refer to a combination of air and liquid cooling. Asus showcased their new ROG Poseidon GeForce GTX 1080 Ti Hybrid Cooled Graphics Card with Custom PCB and DirectCU H2O Cooling.
The video card can be either cooled with the included fans – these are the patented Wing-Blade IPSX-Certified fans – or be attached to an existing liquid cooling loop, since there is no pump nor radiator included with the VGA.
The custom PCB VGA comes also with a backplate that integrates ASUS proprietary AURA Sync technology with a series of RGB LEDs
A closer look to the construction of the hybrid cooler reveals that the heatsink is a mix of copper plate onto which a flat liquid channel is soldered (just like a heatpipe, but for the liquid to flow through it) and standard flat heatpipes that remove the heat from the mosfets and transport it to the same copper plate that covers the GPU chip. A clever design, but as ASUS themselves noted, this means that on air the GPU will run a bit hotter with than a normal heatpipe cooler.
The real advantage of such solution can be seen when integrating the cooler inside an existing liquid cooling loop, since on air only, there is no heatpipe that helps removing the heat from the copper plate on top of the GPU, which by the way already dissipates the heat coming from the mosfets… The hybrid cooler should be capable to cool the GPU to under 50°C under load with liquid cooling and under 70°C with air cooling, ASUS noted. Of course, temperatures under liquid cooling can vary depending of what else is cooled within the loop, but 50°C seems a pretty reasonable value for a liquid cooled VGA.
Power will come through a 8+6 power connector configuration, and no clocks speed were revelead as of now. Still PC enthusiast can expect to have some overclocking headroom due to the custom PCB, as usual with ASUS ROG graphic cards.
We will update the story as soon as we have more information.
