ASUS Strix GTX 970 OC 4 GB @ techPowerUp
 

ASUS has just released their GeForce Strix GTX 970 OC, an overclocked, custom-PCB version of the GTX 970. What is special about the STRIX technology is that it will shut off the fans completely during idle, media playback and light gaming, resulting in a completely noiseless experience.
