https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248901 --- Comment #2 from Martin Birgmeier <d8zNeCFG@aon.at> --- Actually the behavior is that it suffices to *once* execute the sysctl; after that, the critical temperature warnings are printed every few seconds. Are you sure about the "poor cooling"? This is a laptop, and I am regularly cleaning the cooling ducts & servicing the fan, even partially disassembling the system. My impression is that this is "by design", and that the processor simply throttles when reaching about 97 °C - although this is not visible when looking at dev.cpu.0.freq which stays at a constant 2 GHz. But it never goes beyond that temperature (and the system has never been unstable because of it). Also, even if I try to use an external fan to add some cooling from underneath, the temperature stays in the range of 90 to 97 °C as long as all four cores are active. -- Martin -- You are receiving this mail because: You are the assignee for the bug.help
