My understanding is that in order to minimize the overall energy consumption, the scheduler will try to maximize the cpu frequency and minimize the total time of computation… So a cpu scheduler will not help much here, as they will all schedule 100% of the cpu. AFAIK, there is no scheduler that allows saying "schedule this so that so that the fans don't go on". >From the amount of complaints about loud fans, I think it would be a popular feature. (There is something similar with "lap protection", where heating is avoided if the laptop is detected as not-on-a-surface). Please try with the following file: # /etc/systemd/system/plocate-updatedb.service.d/limits.conf [Service] CPUAccounting=yes CPUQuota=20% (then 'sudo systemctl daemon-reload && sudo systemctl restart plocate-updatedb'). I think this could work.
