Sounds like a useful script, but is 71C really too high? The fan in this i5 Intel NUC, admittedly much younger (just a few months old), doesn't start until the CPU temperature reaches 90C. No doubt you've done your research, so by all means ignore me if you want to. > I am in the process of setting up distcc to try and help distribute the > load while limiting the i5 to -J2 which I hope can speed things up > whilst still keeping its cool. That makes me think a bit. I used to use a 24-thread Ryzen M9 as a compute host with smaller machines being NFS-mounted into a chroot, which worked well, but that beast has become too noisy. Now I just use the Gentoo packages where I can. -- Regards, Peter.
