I was worried for a bit when I got into the UEFI (BIOS), I couldn't turn the fan down below 60% duty cycle, and the CPU fan that is now handling they case was vary audible even at that speed.

But I installed Windows 8.1 (without a key for now, still not sure if I'll buy it) and added the Asus utilities. OK, the Fan Xpert 2 is awesome! It mapped the fan's duty cycle vs. cooling and let me slow them down a lot more than the UEFI settings would allow. Now everything is peaceful.
