@maXterm @brousseau6933 see post #10 for cable method. disconnect the GPU fan connector from GPU board, connect it to motherboard's Sys_Fan connector via a special cable, ...
Using atitool-mac-amd64 on the RX580 firmware, I see that BIOS defaults for Temp are: min 40C, med 65C, high 85C, max 109C while corresponding Fan PWM settings are: min 20%, med 40%, high 60%, max 100%. This seems like a fairly aggressive curve, resulting in a default fan speed of 40-60% from 65C-85C (i.e. under load), which is close to my observation after 10.14.4 sleep.
