https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248901 --- Comment #2 from Martin Birgmeier <d8zNeCFG@aon.at> --- Actually the behavior is that it suffices to *once* execute the sysctl; aft= er 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 process= or simply throttles when reaching about 97 =C2=B0C - although this is not visi= ble 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 underne= ath, the temperature stays in the range of 90 to 97 =C2=B0C as long as all four = cores are active. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
