Hello guys! I just built a new machine to replace my z97 4790k setup. I am using a MSI x570 Gaming Plus mobo (Latest BIOS) with a 3700x. Everything seems stable and temps are in check, however during POST my GPU(MSI 2080 Trio) fan speed ramps up to 100% for 3-4 seconds or so then calms down right before windows boot. I've read a couple of reddit posts about this behavior as well, from other users after switching to 3rd Gen Ryzen CPUS. As soon as they switch their CPUs back to 1st, 2nd Gen - the GPU 100% fan speed issue disappears. Seen posts like this from B450, x470, x570 with various chipsets and boards from ASrock, MSI, Gigabyte etc. From various GPUs as well. And it all comes down to the 3rd Gen CPU. I am yet to see this being brought up here on guru3d. Not finding any clarification about this via google so i am trying to get info/feedback from you guys. If anyone has any more info about this, please let us know! Peace!
