new tech support go-to will be, "have you tried to plug it in backwards"

It doesn't vary too much. It depends on fan model or radiator model because of how the fan shrouds seat against the face of the radiator. I believe having the fans in a push configuration is slightly better. Having the fans push air through the radiator, not pull air through. I recommend doing some more looking beyond my response though because I could be wrong.

The VRMs are liquid cooled. The remaining fan is mostly decoration, but it does help move some air around the end of the card it is on. There is a metal plate under the remaining fan area that both holds the fan shroud to the PCB and acts partially as a heatsink. Yes the Radeon 7 gets quite hot if you let it. The two I modded are doing fairly well, usually sitting around 60C to 75C with high graphic settings at high resolution in games. They display to a 5 monitor array. The noise level is loud for the stock cooler configuration when the fans ramp up, but I have not run any of mine very long with the stock cooler. The single fan after the mod does not make much noise as it doesn't really ramp up from its base speed.

I had some wacky RGB issues with my Asus Prime X399-A motherboard where my RGB was not being controlled or sent power through the headers too. If you still have the issue, I found that Asus Armoury Crate RGB software was able to get the motherboard's headers working properly. It can be found on Asus's website and I recommend it since part of it is directly for Asus motherboards.

The RadeonVII has a nice fan shroud and I didn't want to slap a full cover water block on and leave the fan shroud to waste. I modded some Bykski full cover blocks to fit inside the fan shroud, tubing and all, even allowing one of the shroud's fans to remain. This came out super nice and it actually makes for some neat custom loop setup options in the case chassis. I have both GPUs staggered in vertical mounts, one in front of the other. Routing the tubing out the end makes it easier to connect the rest of the cooling loop to the GPUs when mounted this way and gives more flexibility with mounting them wacky angles or heights. I'm sure the types of GPUs this mod could be done with are limited, but showing off the idea. Even has custom RGB in the fan shroud too.

This is a late response, but my system uses a Radeon VII and I have had only one or two real problems with it. Gaming wise, I think the card is great. It is not the perfect video card for gaming, but I am running most games on a mixture of high and ultra high settings. I want to note that I'm also running 5 displays with the card (resolution: 5400X1920 60Hz). Since different games can have varying graphic load here is samples of the games I usually play with it: Kerbal Space Program, Project Cars, StormWorks, Transport Fever, Beseige, Cities Skylines. The problems I have had with the card so far are keeping the card cool and the recent drivers don't like Mirror's Edge (the March 2020 radeon update). In Project Cars and some other games I ran, the drivers before the March 2020 update had a problem with reflective surfaces. The issue has since been fixed, however during the time the problem existed, reflective surfaces would have their textures appear as colored lines. The texture would still be comprehensible, but very noisy/grainy with several thin lines (almost looked like those stereoscopic 3-D effect picture cards that you tilt to see different images) My Radeon VII is water cooled on its own loop and I was able to fix the heat issue by modifying my case some to allow more exhausting air to pass through the radiator's area. I really recommend having a water cooled loop for the card because it can get hot VERY QUICKLY. Having the water cooling loop for the card slows the acceleration of the temperature climb from the extra thermal mass. The card currently runs at cool to upper moderate temps while gaming. My reason for having the Radeon VII is the advantages it provides with workstation uses. I do 3D modeling and have done work with some CADs like Autocad and Microstation. The Radeon VII's fast memory and ability to use shared memory seems to work nicely for large CAD drawings and large 3D environments. Plus I went to this GPU after using two RX580s for a while (sometimes in crossfire) and the radeon VII actually runs less hot currently than the two air cooled RX580s I had. TL;DR: Gaming is great, driver problems do exist, but have lessened over time and are usually not large problems to deal with. The card gets very hot very quickly if you do not have an actually good cooling method for it. Advantage to this graphics card is if you do any workstation tasks like rendering environments. Sorry for such a long response, but I figure you are possibly looking at buying one so i wanted to include some extra details before you possibly buy one.

R20 .060 CPU test results on a 1900X 4GHz ThreadRipper build. Also sorry for strange resolution (uncropped multi-monitor). Screencaps show both multi and single core scores. (build has two RX580 GPUs in crossfire)
