TechPowerUp posted a review on the Sapphire R9 390 Nitro 8 GB
A quote from the article:
Sapphire's R9 390 Nitro is equipped with a triple-fan cooler that runs very quiet and also delivers good temperatures of only 65°C during heavy gaming. The card, which trades blows with the GTX 970, is also overclocked out of the box and provides a dual-BIOS as an extra safety net.Sapphire R9 390 Nitro 8 GB @ techPowerUp
