Mobo- here I looked at Z390 with WiFi boards and there were not a lot of options. That landed me at gigabyte AORUS pro with WiFi. Looks like it should do all I need? Thoughts?
I'm going to issue a warning against Gigabyte's Aorus intel motherboards.
When TR tested the Z370 Aorus Gaming 7, they ran into overheating VRMs
Although getting my manual overclock dialed in was simple enough, my testing did raise some concerns about the effectiveness of the board's VRM cooling arrangement. While I tested the 4.9 GHz CPU Upgrade profile with Prime95 Small FFTs, [...] Even with the Gaming 7's small VRM fan in action, I observed temperatures from the VRM MOS sensor rapidly climbing over 120° C, at which point I stopped the test.
after I took off the VRM heatsink for pictures and gave it a thorough torquing-down on reinstallation, Blender load temperatures for the VRM MOS sensor fell to about 91° C under extended load with the 4.9 GHz CPU Upgrade profile, and Prime95 Small FFTs topped out at 124° C without the startling climb that I observed in initial testing. Those numbers are still high, but they're probably not alarming in a typical enclosure with more fans around the socket.
So, they got thermal runaway on the VRMs, and 124C once they reapplied the heatsinks. They note in their review that the VRMs were mostly cosmetic, with more RGB wiring than actual heatsink.
I ran into similar problems with my Aorus Z370 Gaming 3. My VRMs get up to 126C in Prime95 on my 8700K, which is enough to start thermal throttling, even with the CPU only at 60C with a H100i AIO.
The Aorus Z390 looks like it has similar design elements, I would research it thoroughly before buying, as the 9700K has 33% more cores than the 8700K. I've been able to get longer sustained OCs at 4.6 GHz 12-thread by undervolting the CPU, but I'm going to stop by Frys sometime this week and get some stick-on VRM heatsinks to see if they will curb this issue.
