Offler, can't tell you why but just intution. The Radeon VII reminds me of my R9-290 cards - stout but runs a little hot (they (had 2 in CF) ran hotter than the Rad VII does.
I had replaced a custom water cooled GTX1080 (EK block) with the Rad VII so I could have an ALL AMD rig. I own a Custom water cooled GTX1080TI rig(see below) and the price jump to the GTX 2080TI was too high. A GTX 2080 was also a possibility to replace the GTX1080 but when the Rad VII appeared, I decided it was what I wanted.
I have now ordered a Bykski fullblock (ships after 3-25-19) to put the Rad VII under water.
I remember when I put the R9-290s under water, they "came alive".
Perhaps it's wishful thinking but I hope the Rad VII shows the same "liveliness".
We shall see. Preliminary reports from those doing water cooling, Games Nexus and Igor's Labs seems to show promising results.
