lmao no mods for me. I've got it sorted anyway. In bios there is a "q-fan speed". For the start speed i enter 45 degrees. For the full speed i enter 55 degrees. The rear chasis fan never goes above 1670 rpm which is good, even when temperature goes over 45 degrees etc. I guess that it thinks for starting temperature when the computer is first turned on and after that it doesn't matter. Apart from that i manually put starting voltage down from 5 to 4 volts. My cpu fan is directly attached to a pci fan controller so if i want to overclock and put fan on maximum can edit it with ease. Front case 120mm fan stuck at 1200rpm average which is good stuff.
