![]() You would now see cores reach, and stay at, 70☌ instead of 100☌. Will trigger CPU slowing effects at 100-30=70☌. I couldn't find the right subsystem symbolic link to reach it, so here is how I find it (location will probably vary on each system): $ find /sys -name tcc_offset_degree_celsius 2>/dev/null In practice that will mean the CPU will reach the newly chosen temperature and stay there, and the fan having less heat to evacuate, will spin less noisily. If you're worried about the temperature, or more probably annoyed by the fan speed at its maximum, some Intel CPUs (at least Haswell ~ 2013, Skylake or later) along quite recent enough kernel (probably >= 5.4) have a setting to artificially add an offset to lower the temperature threshold (high) at which it will start lowering its speed. Once it reaches the high threshold, in addition to active cooling (eg: fan), other method(s) available for the CPU will be used and among them lowering the CPU speed: so the CPU will reach 100☌ and stay there due to the negative feedback loop. Same sensors command should tell that 100☌ is the high temperature threshold eg: Core 0: +37.0☌ (high = +100.0☌, crit = +100.0☌) ![]()
