NEVER buy a mobo with a proprietary fan in it! Never! If that fan breaks, and I have had two fans on mobos do exactly that, you have to either kludge a fan to cool the board or throw the board away. MSI even brags that the fan embedded in the heatsink is "patented" so good luck buying a replacement fan somewhere. If you DO buy this mobo, immediately order two replacement fans for it from MSI as insurance (if that is even possible). Better yet, skip this board.
