Asus fixed the little defective fan before I bought my board luke, I just rushed out and bought my board before researching it properly so I really am a git for buying up old defective stock without looking into it.
I listened to all the hype about how wonderful the Asus boards were and trusted the brand........ then of course I got lumbered with junk... no software SLI switch, faulty fan.
The new type fans on the Asus board have the fan oriented at 45 degrees on the board and not square to it, that's how you can tell the difference.
I did not have any of the compatibility or installation problems that others reported with the Asus board and other identical hardware and bios versions. This leads me to believe others simply don't know what the heck they are on about and they have made other errors that led to their results.
I can vouch for Gigabyte mainboards in general. They have excellent build quality, good features, good documentation, good looks and have been reliable products in my system builds.
MSI used to be the "budget" offering a few years ago.
I look at the red MSI PCB's and component layout and it looks cheap and untidy to me., but that's just me.......
MSI have been around a long time building up a good reputation and offer products with great specs.
Had that Gigabyte board been available to me at the time I purchased, I would have seriously considered it.
