The next overheating thread with Linux

Hi,

I'm quite disappointed with this issue still haunting us [as I'v seen allot of threads still going on]  I'v used to many laptops to say that this is related to only a kernel, laptop itself or to hybrid graphics (I have also a laptop with just one single intel graphic and runs hot as soon as you do something)....

I'v got my new laptop with 16GB and i7-4710HQ which was especially designed to be cool and run smoothly (did some research before buying). And most of the time if I'm doing just normal stuff it runs at 45 - 50C but as soon as I try to compile something , like firefox or similar the CPU practically melts going up to 90C , now what actually made me to open this thread is that I just did an update and the package was big, and the temperature went up to 70 just for pacman checking the package signature... I mean are we kidding?

Now the reason I'm opening this is to find a real cause and solution to this issue and not just trying to emulate microsoft - patch over trick/patch over workaround style of fixing stuff. This ... is ... Arch Linux!!!

Oh and please don't tell me it's normal. I remember perfectly compiling programs on OpenSUSE (a loooong time ago) when it was still running on 2.6 and none of this was happening.

Thanks.

Re: The next overheating thread with Linux

r0b0t, just a hunch but did those systems have intel processors and use intel_pstate  / powersave setting?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

.. again it's like there is no handling for those situations.

Re: The next overheating thread with Linux

For clarity, you are using the aur thermald package ?

Have you tried without any userspace tools or just cpupower ?

Re: The next overheating thread with Linux

Yes, I was using thermald (latest git).
I tried with cpupower in powersave and downclocking the CPU's to 1400Mhz and the temperature has a max of 55C which is absolutely fine, but :
- compiling takes forever
- doing other tasks it's way slower that usually

Yes tricks may do some good but what's the point of an 8 core when you cannot use it and instead you turn it in a celeron or something like that...

Re: The next overheating thread with Linux

What cooling do you have? I'm running a Xeon X5670 overclocked to 3.8ghz and it idles at 22C and never goes above 60C load.

Are these temps linux specific or do you see similar temperatures in Windows?

22C? that's awesome, no on windows it doesn't happen, I even played heavy games with no problem.

So, are you telling me that your processor stays at room ambient temperature?  Or does your system live in a refrigerator?

How? My i7 laptop idles at 42-45C with thermald and performance governor. Things that spike the temperature: html5 youtube videos, Facebook video call (the worst). When playing Wasteland 2 the temp goes up to 80C, not sure if that's normal.

Re: The next overheating thread with Linux

With kernel 4.2.3 onward my i7 temps in Arch match my Ubuntu 14.04 LTS temps. In your case is your laptop using nvidia graphics? Also if on battery install TLP that throttles CPU and turns turbo off to save battery life.

Re: The next overheating thread with Linux

I don't plug in the battery "to save it for when I need it" and yes, the graphics is nvidia but is completely disabled with bumblebee. I don't care about graphics on Linux, intel it's just fine, however it's really a shame having to "tweak" it in order to save your motherboard and limiting extremely the performance of the system only because the kernel doesn't know how to handle the situation.
