Still an RX560: amdgpu-pci-2b00 Adapter: PCI adapter vddgfx: 887.00 mV fan1: 1610 RPM (min = 0 RPM, max = 3600 RPM) edge: +42.0°C (crit = +94.0°C, hyst = -273.1°C) power1: 22.09 W (cap = 48.00 W) > My initial guess is that this is either A: bad data / false positive > (i.e., it's not really that bad under the hood), or B: a limitation of > the Linux-side drivers. It's plausible that there's something in power management that can and should be turned on, and isn't. -dsr-
