A couple of problems with Asrock X570 Taichi

That is odd, I will check it out on my X570 Taichi as soon as I have some free
time, probably Wednesday. I don't have these issues with 1.80 on my board
however. When my system enters sleep it reboots to wake, not exactly normal but
then again, I have not done a fresh OS install on it yet so I need to take care
of that first. If you have not performed a clean install on this system (used
the OS drive from a different system) then that would be a solid first step.

Sleep was problematic with both first and second gen Ryzen for quite a while
after they launched. I suspect the issues are 2 fold, the AGESA and the OS. I
had endless issues with sleep on my X370 Taichi and 1600x, I tried countless
BIOS versions and in the end, the issue just disappeared, seemingly on it's
own. Checking my logs I discovered Windows had updated itself while I was out
and that was what eventually fixed it.

As for the chipset temps, good exhaust airflow is essential with these X570
boards, you want to pump the heat out of the case as quickly as possible. I
typically run my systems with positive pressure (more intake than exhaust) and
noticed my temps were pretty high. Balancing the pressure a bit better dropped
my chipset temp by about 5c. If 60c is a load temp however, that is pretty
decent for an X570 it seems. I have seen reports of temps up to the low 80s
under load and apparently, up to 85c is within "safe" operating temperature.
Still no official word on max operating temps for the chipset but I would aim
for sub 80c, a spike or 2 over that in an hour long stress test is fine but the
average should be under 80c, if for no other reason than to limit heat
saturation of surrounding components as well as dumping hot air into your case.

I figured an interesting thing. In my case GPU was affecting the setup. I have Sapphire Pulse RX 5700XT, and basiclly by default, it has very passive fans policy on low load. GPU temps are quite high, and that's what's negatively affecting the heatsink and everything under it (nvme and the chipset).

I just tried radeon-profile: https://github.com/marazmista/radeon-profile and set more active fan curve. GPU temps dropped down, as as well as chipset went from 60C to 56C! Nvme went from 45C to 41C! So now I know what needs adjustment.

I wonder if putting some insulating material between the long edge of the GPU and the heatsink could improve things further.

Yeah, good point, I'll give it a test. How much bandwidth does a GPU like RX 5700XT saturate? I guess it depends on the screen resolution too? Given that both board and card are PICe 4, I suppose even x8 bandwidth will be like x16 of PCIe 3?

I would just drop the GPU into a lower slot. PCIe 4.0 x8 is more or less the same
as PCIe 3.0 x16, you are correct. The 2080ti doesn't saturate PCIe 3.0 x8 let
alone x16 so you should be fine with the 5700xt at PCIe 4.0 x8. If you are a
curious sort like myself, you can have a bit of fun benchmarking the GPU in each
slot to check for differences yourself. I strongly suspect you won't see more
than a margin of error difference even with the x4 slot
