Temperature too high when high overload
Hi all, I just switched from Fedora Linux to FreeBSD. But I noticed a problem, the CPU temperature will be very high when the load is high. Especially while I am building C++ programs. It shut down for even 3 times while I was building Firefox/Thunderbird, just because of high temperature (86.5C). One of my friends told me, FreeBSD doesn't support your ACPI well but I noticed that while I'm not compiling ports, the temperature will be not too high. Just now I'm building LLVM, here's what I've seen: sysctl hw.acpi.thermal.tz0.temperature hw.acpi.thermal.tz0.temperature: 84.5C pkill make sysctl hw.acpi.thermal.tz0.temperature hw.acpi.thermal.tz0.temperature: 67.5C I'm using Dell Vostro 3400 laptop PC with FreeBSD 9.1-RC1. uname -a FreeBSD bsd.laptop.mike 9.1-RC1 FreeBSD 9.1-RC1 #0: Tue Aug 14 04:25:06 UTC 2012 r...@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 There's my dmesg message: http://slexy.org/view/s21b7xTTsu Anyone knows how to fix this problem? Thank you.

I did not look for the CPU this machine has. My notebook has a i7 and it runs on 96 degree centigrade when the CPU is under 100% load. It would shut down at 99 degree centigrade. uname -a FreeBSD bsd.laptop.mike 9.1-RC1 FreeBSD 9.1-RC1 #0: Tue Aug 14 04:25:06 UTC 2012 r...@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 There's my dmesg message: http://slexy.org/view/s21b7xTTsu Anyone knows how to fix this problem? Thank you. I do not know much about the differences between i3 and i7 but I would expect that both can run until 99 degree centigrade before they have to shut down.

It shut down for even 3 times while I was building Firefox/Thunderbird, just because of high temperature (86.5C). Mike, 86.5C isn't really all that hot for a modern 4-core laptop under load; like jb below, show us `sysctl -a | grep thermal` so we can see its passive cooling and critical temperatures. I used to have the same problem with my laptop (i5) and this can be fixed by lowering the temperature threshold for passive cooling.

Christian Modulo adjusting the right thermal zone, this is safe advice; you can always edge it up later, assuming it helps stay at say 10C below _CRT.

And your _PSV 95.5C and _CRT 100.0C aren't uncommon sort of values these days, hence my surprise at Mike's (apparent) CRT shutdown showing 86.5C. On the other hand, even my 1133MHz P3-M can go from 50C to 60C inside one 10-second polling interval under applied high load, so a shorter hw.acpi.thermal.polling_rate may help trigger _PSV well before _CRT. cheers, Ian___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
