Traditional Nvidia video card manufacturing partner Zotac has an interesting GeForce GTX 660 Ti implementation with a custom PCB design and probably the test cooling system ever to be mounted on a GTX 660 Ti video card.
The official name of the product is Zotac GeForce GTX 660 Ti Extreme and the huge PCB is the same with the one used on the company’s GTX 670 Extreme line, featuring two power connectors and a 13-phase VRM power circuit.
There is one 8-pin power connector and a 6-pin one while the cooling system
has impressive 8-millimeter heatpipes and two fans with a 92-millimeter diameter.
Although the 8-mm heatpipes are more efficient than classic 6-mm ones and usually three of such heatpipes do a better job than five 6-mm pipes, the company has decided to use no less than five of them.
The copper cooler is reportedly
nickel-plated so there shouldn’t be much worry about oxidation.
The performance of the card is really impressive as the factory overclock makes it faster than a standard GTX 670 while the impressive 1401 MHz overclock managed by the hardware experts at Expreview.com and the 7608 MHz memory frequency made the card compete with a GTX 680.
