 |
|
Right now I'm compiling and installing kde-meta and my Thinkpad T420 reached temperatures of 97C
I ended up having to get a bag of ice from the fridge to cool it down but I was wondering if there's anyway to prevent the laptop from heating up as easily?
From what I understand, Thinkpads have a history of being extremely durable and not heating up to such extreme temps.
my /etc/portage/make.conf has it set so that there are 2 parallel computations going on, previously I had it set to 3 but I tried tuning it down to see if that would reduce the overheating that happens.

Thanks, that seems to have worked, my temperatures have been stable at around 72C give or take 4C
Now I won't have to put nordic ice under my laptop everytime I compile

Maybe this sounds stupid but have you clean the fan, the heatsink, and changed thermal compound on cpu? T420 is very durable but quite adult. Thermal paste can be turned into a stone and loses its functionality after some time. 97C it is a way too much even for the compilation IMHO. |

| Might also work to set the cpufreq governor to ondemand (not schedutil!), then there's a control file somewhere in /sys/devices/system/cpu/ that causes it to ignore nice > 0 processes. Portage will be able to use all cores, but it won't increase the clock on its own. |

I got my T420 refurbished from someone on ebay a month ago, so far I've been running Fedora on it and beating it to hell with programs that I've made but the only time I've ever seen it reach temps this high is when I'm running emerge on a lot of packages. I've searched up the issue before and it seems like other people were also having trouble with it but nobody addressed how to actually prevent it from doing so.
As someone pointed out earlier, doing MAKEOPTS="-j1" and emerge --jobs=1 did the trick for me, I collected temperature data while it compiled last night and it averaged at around 72C which is typically what I'd be at if I'm doing anything process intensive. The only other time I've ever gotten temperatures of 97C is when the fan in my ThinkPad T60 got stuck.
