I went with Asus like my mobo brand, I'll never go near Gigabyte again my both last cards were Gigabyte windfoce and altough they were beasts I had lots of issues with them and even physical issues with the windforce coolers, fans started to rattle after heavy use for a while.
The issue with the cooler noise doesnt bother me at all while gaming or while the cpu is in full load doing something else, the noise bothers me during idle time when making simple tasks.
You see there is something really strange about these cpu's with dd4 xmp profile.
If everything is on default on bios without xmp or any oc on the cpu my idle temp is about 28-30c and peaks over doing simple tasks to 40-42c, so I dont hear the cooler fans at all.
The problem rises after applying the xmp profile which for some weird reason slightly overclocks the cpu by rasing it bclk to 125mhz and lowering the multiplier to 29 on all six cores which resaults in slightly oc'd cpu from 3600mhz to 3625mhz.
But this werid method causes the cpu to act really odd only on idle, on load it acts the same way without the xmp profile and the fans rpm are consistent.
When idle the cpu is 10c hotter and peaks on simple tasks from 41-42c to 51-52c, that causes the cooler fans to constantly accelerate when 51-52 and slow down when 41-42, that's the noise that drives me mad.
I hope you understood when xmp is off and the temps peak from 30 to 40 there is almost no change in fans rpm in those kind of temps but when the cpu seats when idle on temps that constitute a turning point for the fans than it really becomes annoying.

maybe some bios setting that can change it, turbo boost or something
and your right about the gigabyte windforce ones, there are issues with them
some guy on tomshardware mentioned:
Apparently there are currently some issues with X.M.P. on X99 platforms. Setting it to auto until more mature BIOSes is the only solution at the moment.

The turbo boost is disabled with xmp on and yeah at the first week it gave me hell, bsod's and sometimes boot faliures, since the mobo is out it had 3 bios updates already.
I updated the bios twice and stuff seems to be super stable now with the latest version, still this thing with the cpu remains a mystery to me.
I'm still wating for a response from Asus but I think that they dont even have any idea about the new x99 platform..
glad its stable now though
