I am writing to confirm the Mugen 2 works great on the MSI DKA790GX Platinum! I saw there was some confusion to it but I'm here to clear it up
I will post pics in a few days when my camera gets back.
edit: here are a few pics. I couldn't get real close to the heatpipes because it is in the case but there is a good bit of clearance on them. Click link for bigger picture. Sorry for the poor camera quality I was in a rush.
