"The ASUS STRIX GTX 970 DirectCU II OC will fit into many computer user's artillery as the component of choice. With its sleek black styling, large aftermarket DirectCU cooler and efficient design, this card packs a punch while maintaining optimal temperatures with minimal fan speeds and noise. The ASUS STRIX GTX 970 has a 10mm thick copper heatpipe that transports 40% more heat than traditional heatpipes, and a 220% larger heatsink area for more efficient heat dissipation."
