Make sure the case fans are properly installed (including facing the right direction) and that the case has adequate ventilation.

There are a few things that can be done to stop this: Ideally, they should hit max speed before max temp.Īnd supposedly keeping temps significantly lower can help improve the lifespan of parts (I believe it but I've also never seen rigorous data on this for modern systems) Once they hit one of those limits, they will stop going faster and potentially may even slow down to keep from over-shooting the temperature limit. Processors generally run at variable speeds and will often attempt to go as fast as possible until they hit either the max speed set in the bios or the max-rated temperature. That said, it's not ideal because it means there probably is some bottleneck somewhere in removing heat from the processor. The processor has been set to run up to that temperature limit, and it's considered by Intel to be safe. Sensors will not know about this except displaying the temperature is now 70☌ (which is really the case), but I understand the kernel-related tool turbostat has knowledge about TCC and should be the preferred tool to set the temperature (using -TCC) if it supports the feature for the given CPU (probably meaning it knows what subtraction to do).Ĭontrary to some other answers, this is normal.Īccording to Intel's Ark page for the 12700K, the Junction Temperature is rated at 100C. 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☌)
