I had an ASUS x570 itx board before, and it ran way too hot. The chipset temperature was at 70-80C with a Fujipoly thermal pad that I replaced the stock thermal pad with. I also used a Noctua A4x10 fan in my Velka7 case but it was just still a bit too hot. I think X570 just runs way too hot for SFF. I initially went with the Asus because I had an Aorus B550 Master and just had quite a few issues, and the one that did it for me was that the NIC would only negotiate at 100Mbps after about a month's worth of use. Since the X570 has Intel NIC I thought it would be better, however it just runs way too hot for SFF.
I got the Gigabyte Aorus B550i and the thermals are way better (55-60C chipset) and in turn CPU thermals are a bit better too. I do have a -25 offset on all core curve optimizer PBO2 set. And I also a thermal limit of 75C. I took some benchmarks in Cinebench R20 and got 624 sT and 5418 mT. There was no impact to single thread but multithread I could get about 6100 on my NH-D15S. A 10% hit to multicore isn't too bad for my use case.
I just got notification saying that MTA18ADF2G72AZ-3G2E1 is in stock and they are shipping it to me soon. That's pretty cool, sooner than expected.
I use it for both gaming and work -- so when I'm sitting at my desk during the day, it's downstairs. Then at night, I bring it upstairs to game.
