Do you have the big ass heatsink + fan on it ? https://www.friendlyarm.com/index.php?route=product/product&path=82&product_id=133 On my pine64 (Not LTS so A64), when it's idle the three sensors are ~22C. My IR thermometer reports a max temp of 33C when I 'scan' the chip. Could you sysctl dev.aw_sid.0.ths-calib ? I'll try to test on my NanoPi 64 with the heatsink. > and it?s summer here. > > danny > > > > > With 4 cpuburn-a53 process running I easily get to ~60C for cpu and > > ~55C for the gpus sensor. > > https://people.freebsd.org/~manu/cpuburn-a53 <https://people.freebsd.org/~manu/cpuburn-a53>; > > > >> This was during a -j4 buildworld's: > >> > >> Building /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/lib/clang/libllvm/CodeGen/MachineBranchProbabilityInfo.o > >> Building /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/lib/clang/libllvm/CodeGen/MachineCSE.o > >> Building /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/lib/clang/libllvm/CodeGen/MachineCombiner.o > >> Building /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/lib/clang/libllvm/CodeGen/MachineCopyPropagation.o > >> > >> No HDMI is plugged in.
