3x Sapphire 7970 and 1x MSI 7970 OC
The most noisy thing is that MSI with reference cooler. It seems i have finally found a buyer for that card and i can replace it with another Sapphire. After that it will be pretty silent (at least compared to that MSI -> MSI on 70% fun speed is like 10 times louder than Sapphire on 70% fun and its also generating more heat...)
