Soldato
I can tell you that the MSI Armor OC cooler was quiet at 100% speed, and had to turn off the 3 Vardars bellow 50% to hear it (working at 80% 24/). While is very efficient allowing the card to work at 2139 core. (WC was doing 2190).I cant decide on founders or custom either ... hard choice ! Really can't be doing with noisy gpus nowadays ... how bad is the 1080 founders compared to say the strix 1080 ?
To put in perspective the Gibabyte 2 fan GTX780 cooler, was loud as a hair-dryer.
Just my experience with after market coolers
