This is a great motherboard but not without it's issues
Like almost all x570 motherboards, the south bridge chipset gets really hot and so has an awful chipset fan on it. This stupid thing is loud and high pitched but there are a couple ways to fix this:
Option 1 is an easy first step but 3 is the real solution. The original idea and some help/advice was from this reddit thread
The main point of this mod is to replace the existing thermal pads with a more thermally conductive solution. The tricky part is that at least part of this has to be non-electrically conductive so you don't fry your board. Parts you will need:
I found that (with chipset fan off) with the original stock setup, SB chipset temps would sit in the low 60s when idle but quickly climb to 70C under load where the fans would kick on.
With this mod, idle temps were in the mid 50's (idle temps really mean nothing though) but the load temp was around 63C. No need for annoying chipset fan anymore! :D
I found that the default settings were not optimal for my card (Gigabyte Gaming OC). The max fan speed was too low and so it frequently throttled. The good news is that this is fixable
I found that with these settings, under load (stress test), gpu temps were reduced to the upper 70's, junction temps stayed around 90C, and memory temps in the upper 80's. This was much better than before and eliminated any throttling.
For reference, Max junction temp is 110C and max memory temp is 105C (although you don't want to be near those if you can help it obviously)
Note that the actual clock speed will be around 50mhz less than what you set though. So if you set it to 2000mhz, it'll typically max at around 1950mhz
You can underclock the GPU and as a result, undervolt even more. I found that if I underclocked to 1955mhz, I could undervolt to 990mv and keep the stock fan settings. The gpu was practically silent under load but you will take a small performance hit
Ryzen Master won't open if any kind of windows vm stuff is enabled (like Hyper-V). This can be fixed with a simple hex edit as outlined here
