How to protect my computer while folding? - Page 3

post #21 of 27
Well your CPU has a set temp wherein it will throttle itself, but ive not heard of a programme or feature that will automatically shut your down if it gets too hot or your WC leaks?

double checked, all the options i have for acpi are enabled, still nothing on the modinfo thermal tho...i will contact asrock and ask them about it, but i don't have any high hopes for a proper response.

not sure about if it leaks or not, but there are ways both in linux and windows to have the machine shut itself off if it hits a certain thermal limits. we are mainly discussing ways to do it in linux, lloyd mcclendon is offering one way to do it, without further testing, wont know if it will work with all systems (as of right now it does not work for me, since the module doesn't load by default, and when manually loaded it doesn't report anything.), so till i can get that sorted, one option for me is to setup that script to do it.

does lsmod | grep thermal show anything ... how about dmesg

you really need to wipe out any .config you have and start empty, carefully go through and read the help text on every single option one at a time. i did that way back in 1999 and while a bit painful and time consuming, it was certainly one of the most valuable things i ever did knowledge wise.

i would never ever want to use a kernel that ships with a distro. ick they have to bloat and comprimise it such that it will boot everyone's machine... half assed

Found this off Google. http://appscout.pcmag.com/utilities/...id=S1pHSm4m08i For those Windows Users, Better paying $8 than a New CPU i suppose.

dmesg doesn't show any serious errors, ran it again right after trying to load up thermal module, but didn't show any errors for it.

lsmod doesn't turn up anything for thermal either...so its just not loading and not erroring out either...hmm.

yeah i probably should build a custom kernel today, i've been putting it off since going to 11.10, usually the generic is pretty decent, but there are somethings i want to try to improve on keep you posted tho.

alright now that I am home in front of a linux machine, I am getting the same behavior as you are with the thermal module.

# find /lib/modules/`uname -r` -iname "thermal.ko"
#

So it's not there, idk why modprobe is just completing silently instead of saying it doesn't exist...

# zgrep -i "thermal" /proc/config.gz
CONFIG_ACPI_THERMAL=y
(and some others)

So I have it compiled IN to the kernel instead of a module. I guess that would be correct considering I would never want to unload it on this machine. Well... modules are also useful in that it makes it a lot easier to pass parameters to them.

So either rebuild as a module, or append the parameter to the kernel= line in grub. ick Yeah a module would be better, but actually I think I would still prefer it static over a module as I don't want it somehow getting unloaded.

# grep -i -C 5 thermal /usr/src/linux/Documentation/kernel-parameters.txt

looks like I can add thermal.crt=50 to grub, and reboot..

to test, burn the cpu a bit

$ x() { cat /dev/zero > /dev/null & }; for i in `seq 1 8` ; do x ; done

watch cpu heatup past 60, machine should reboot and hopefully sync the disks before. Then adjust the value to something unexpected like 80. I agree 100 is too high, that tubing and fitting were extremely hot, enough to burn my skin and certainly a chip.

edit: just tested and this apparently does not work. set the value to 50, i see it in /sys/fs/module/thermal/parameters, i have the cpu pegged at a cool 55 degrees (no more airbubbles FTW) and i'm here typing this, not rebooting. *** .. will research further.

well me and thrgk played around with one of the scripts from on the links previously posted, and setup a cronjob for it, so if it ever goes to the max temp, it runs the shutdown command.

i will post up a guide tomorrow on how we edited it if you like

edit: the script might be the easier route for most here, as most don't want to dick around with a custom kernel, not everyone is cut out for the gentoo way
