I've not gone into how loud they are, just remember on my NF7-S v2.0 the northbridge fan failed, ended up just putting some massive blue heatsink on it and it was fine, x570 might work out the same.
Post codes seem less of an issue on AMD side, basic lights work, CPU, Ram, mobo, hdd. Fair enough, but some boards lack these led lights too O_O
I've ordered a 16GB kit of 8pack 4133mhz DDR4, gonna see how low I can get the timings to go on my 5820K at 2400/2666mhz lol
Ram prices seem set to rise (see Japan vs S Korea kafuffle), and I now have a kit capable of 3600mhz for ryzen 3900x if I go that route.
