ASUS GeForce GTX 780 DirectCU II Detailed
ASUS unveiled its GeForce GTX 780 DirectCU II OC graphics card, featuring a non-reference PCB, and a new-generation DirectCU II cooler. Its PCB features a strong 10-phase VRM, which is tuned to offer a 30% higher voltage threshold, that much better electrical noise suppression (159 mV vs. 239 mV), and an array of tantalum capacitors that ensure clean power delivery to the GPU. ASUS is offering factory-overclocked GPU speeds of 889 MHz core, 941 MHz GPU Boost, compared to NVIDIA reference speeds of 863 MHz and 900 MHz.
A star attraction with the GTX 780 DirectCU II, is its new-generation DirectCU II cooler. It uses a CoolTech fan, which made its debut with the GTX 670 DirectCU Mini, and which is a cross between lateral-flow and top-flow fans, ensuring greater sweep. The cooler uses a combination of one CoolTech fan, and a conventional top-flow fan towards its rear. This is to ensure the lateral sweep of a CoolTech fan doesn't push hot air back into the case from its rear. The one in the front pushes it out through the rear vent. Beneath these fans is a conventional aluminum fin-stack heatsink, in which a combination of four 8 mm thick, and a central 10 mm-thick copper heat pipes make direct contact with the GPU. The card ships with a back-plate, even though there's nothing to cool on the back side. ASUS plans to launch the card soon.

if their HD8*** doesnt look like that i may be inclined to get one.
The first one looks like cool and innovative, the second, lame fan
And i believe 3 slots?
Who wants more voltage is gonna get more voltage :toast:
Beefy beast ! :cool:
-does asus plan a superclockable gigahertz edition of titan with custom pcb?
so if you design a BALLZ OUT cooler.....it will clock itself higher.....
The last one they had which was for the 7870 - 7850 was considered quite loud by reviewers for a a cooler which intentions were to be low noise.
I wonder if this design will follow the rather loud noise side of things or be a winner in the quiet category as Direct cu II coolers are intended to be.
I ditched Asus DirectCU II cards because of cooler problems. Its OK when it works but Asus have fixed a few problems with them over the last couple of generations.
The 6970 version had a very flexible cooler/card. Felt wonky and cooling performance was hit and miss. The 7970 was better, they made the card/cooler more rigid but still had issues with poor contact. It wasn't unusual for the VRM to reach 100 degress.
The old Asus cooler was big but not that efficient when you consider its huge size. The MSI lightning cooler got better numbers with 30% less heatsink.
This looks like a better quality cooler, looking forward to performance numbers.
apparently best overclocker out of them all and to me the sexiest, i may be having a nvidia card soon!
