Two observations:
First, the whining on Giga boards isn't exclusive to X58 boards. I've got one rig with an i5 750 on a P55A-UD3 and it whines like a school kid who just got his lunch money taken away by bullies if you push the cpu's OC too much. As it's the wife's computer, I just keep the OC down lower than what I'd personally run it and the whine is kept in check, for the most part. Doesn't bother her, at least.
Second, seems Gigabyte is putting some of their capacitors that surround the cpu socket a bit closer to the socket area than most other manufacturers....a little out of Intel's socket clear area spec. This has caused problems for water cooling cpu blocks not sitting flat on the cpu without the underside edges of the cpu block being slightly beveled. Koolance's 360 had fitment problems as did Swiftech's XT, both solved with a rev. that beveled the underside edges of the blocks. This fitment problem was exclusive to Gigabyte boards and did not happen with Asus, EVGA, MSI, ASrock boards, among others.
Probably not a problem for the air cooling set, but water coolers looking to use Gigabyte X58 boards have another reason to look elsewhere, like Asus, EVGA, MSI, etc.
