TechPowerUp posted a review on the ASUS GTX 950 STRIX OC 2 GB
A quote from the article:
The ASUS GTX 950 STRIX comes overclocked out of the box and features an extremely quiet dual-fan cooling solution that makes the card quieter than whisper-quiet during heavy gaming. In idle or light gaming the fans will stop completely for a perfect noise-free experience.ASUS GTX 950 STRIX OC 2 GB @ techPowerUp
