Vega FE + Raijintek Morpheus II Core = ~20C cooler and +10%fps. Since I did a bare bones driver installation the gaming bios isn't available otherwise the fans would spin faster and maybe give a few more fps's. Two Nocua NF-S12A fans are great with this setup. The only down side is I probably killed the warranty but I have a Titan Xp for backup so I'll survive. Oh yeh, installation was fairly easy and straight forward. Now, back to your regularly scheduled program....
edit to add...(for what it's worth)... The Morpheus wouldn't work with Titan Xp.
