The one of the largest and one of the rare Nvidia-only AIB partners, EVGA, has released a rather interesting teaser trailer that shows the upcoming ACX cooler that will debut on upcoming Geforce GTX 780 and GTX 770 graphics cards scheduled to appear by by the end of this month. The ACX stands for Active Cooling Extreme cooler and will be using dual-fan solution with large aluminum heatsink that will handle both the GPU and the VRM. It is safe to assume that EVGA will use this one on factory-overclocked versions of the GTX 780 and the GTX 770 while it will also launch the reference cooled one earlier.
According to earlier rumors, which are now pretty much confirmed, both the GTX 770 and the GTX 780 will use, what appears to be a same or similar cooler seen on the GTX Titan graphics card.
Unfortunately, EVGA did not shed any light on the actual release date of the ACX cooled graphics cards but according to earlier rumors these should come a few weeks after the official launch of the reference cooled versions.
