AC86U running Merlin 386.2 temperatures. Copper shimmed CPU, original thermal transfer pads on radio ICs, 12V 120mm fan running on 9V behind the router. The fan is not attached to the router as suggested in post #221 above, very quiet. RMerlin released the 386.2 and I fired up another AC86U to test it. This router has working radios, was LAN4 LED victim with one VRM only replaced. Update straight from original 41994 beta to 386.2 without resetting anything, 2+ hours uptime.
