[solved] High CPU temp intel without heavy load tasks

Hello,

I just install Archlinux some days ago and i have a problem with the CPU temperature.

I think it is because of graphics, but don't sure

In debian/ubuntu the CPU temp is about 32º and with arch is near 50º

This is inxi -F

CPU is idle at 800MHz and CPU is 48º

I'm pretty sure is about graphic config

Any help?

Thanks

Re: [solved] High CPU temp intel without heavy load tasks

Laptop? Tower?  Racked server?

32º  seems really low.  That is only a 5º rise over "Standard" temperature.  And Spain is unlikely to be much cooler than that this time of year.
50º is not that hot.  I just checked by system at home -- it is a laptop with the lid closed, not doing anything but serving ssh.  It is at about 44º on all cores in a room that is pretty close to 27º

Re: [solved] High CPU temp intel without heavy load tasks

Just as a comparison, my z800 workstation Xeon cores run an average of 40c, in South Texas, office temps are around 75f. If I work them hard, they can get to 70c but that is very rare.

Re: [solved] High CPU temp intel without heavy load tasks

isolate the multi-user.target (to figure whether the GUI causes some load in the IGP) and try to get sensor data on the ambient as well as the fan speed.

Thank you seth, but i don't understand what i have to do. I don't know to do that. Please explain a little bit more.

I have dual boot with ubuntu, and here is the inxi -F

Ubuntu don't use xf86-video-intel, but if i don't install it in arch, i can't get HDMI working

Today is really hot in my home, so temp is higher than normal, but is 38,5º, 10º minor than in Arch.

Can you just try w/o xf86-video-intel (and thus temporarily w/o HDMI)?

It seems xf86 drivers are heating up the CPU

But w/o them HDMI doesn't work sad

May be the problem is with HDMI and i not need de XF86 drivers.
When i plug HDMI it apperars in xrandr but the TV doesn't show up the imge

Thanks

"xrandr -q" output? (w/ intel and modeseting driver)

Re: [solved] High CPU temp intel without heavy load tasks

Well, yes. What if you just run 

xrandr --output HDMI-2 --auto

or 

xrandr --output HDMI-2 --mode 1920x1080i --rate 60.00

?
