ASUS GeForce® GTX 660 DirectCU II dual-fan performance graphics

DirectCU achieves 20% lower temps with direct-contact copper heatpipes and much quieter than reference
Premium alloys in power delivery components defeat heat for cards that run faster and last 2.5 times longer than reference
GPU Tweak helps you modify clock speeds, voltages, fan performance and more, all via an intuitive interface

	DirectCU II *20% cooler and 3X quieter** Flattened copper heatpipes make direct contact with GPU surfaces so heat is dissipated more efficiently, delivering 20% cooler and 3X quieter performance with twice the dissipation area and 6X greater airflow than reference. *Equivalent to 14dB and performance varies depending on system configuration
OC-selected 1085 MHz core 1085 MHz Boost clock for better performance and outstanding gaming experience
	Super Alloy Power Enhanced durability and cooling Exclusively-formulated alloy components boost performance by reducing power loss, enhancing durability, and achieving cooler operation. Choke concrete cores eliminate buzzing sound under full load while capacitors assure a 50,000-hour lifespan: equivalent to 2.5 times longer than traditional capacitors.
