Intel Core i7 fry me up

ivictbor · 2014-09-09 18:54:11

Hi! I have a laptop with Intel:

# lscpu 
...
CPU family:            6
Model:                 58
Model name:            Intel(R) Core(TM) i7-3632QM CPU @ 2.20GHz
Stepping:              9
CPU MHz:               1223.921
CPU max MHz:           3200,0000
CPU min MHz:           1200,0000
...

lmsensors show ~70°C :

# sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +71.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +70.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +70.0°C  (high = +87.0°C, crit = +105.0°C)
Core 2:         +71.0°C  (high = +87.0°C, crit = +105.0°C)
Core 3:         +71.0°C  (high = +87.0°C, crit = +105.0°C)

cpupower show that turboboost is on:

$ cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 1.20 GHz - 3.20 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 1.20 GHz and 3.20 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  boost state support:
    Supported: yes
    Active: yes
    25500 MHz max turbo 4 active cores
    25500 MHz max turbo 3 active cores
    25500 MHz max turbo 2 active cores
    25500 MHz max turbo 1 active cores

Mb the reason in boost? I tried to disable it:

$ sudo bash -c "echo -n 1 > /sys/devices/system/cpu/intel_pstate/no_turbo"

But cpufreq still show me " boost state support: Supported: yes Active: yes"
I also tried thermald (installed and did systemctl start), but it has no affect.
Can you suggest me smth? Thx!

70C is not that hot. What value are you expecting?
What is the ambient (room) temperature?
What are the fans doing?

ivictbor · 2014-09-09 19:28:24

I want to value ~50C (obtained on my dual-boot windows), room temperature 19-20C. Fan works but silent. lmsensors don't show me anything apart core temperature, and I cant see real fan RPM(

@ewaller - 70 C is pretty darn hot for idle, even for a laptop.

I generally find that laptops run a bit hotter, if only because they don't have the luxury of large heat sinks and large volumes of forced air.

I just logged into my dual core laptop which is in a room that is probably 25C, with its lid closed, backlight off, doing nothing (I rebooted it earlier today after I updated the kernel via ssh). It is at 60C.
In the evenings with Chrome, emacs, spotify and claws-mail all under i3, (Average load ~10%) it sits at 73.

I am not arguing that 70C is cool as a cucumber, it is warmish. But IMHO, it pretty much down the centerline of the thermal design.

Edit, OTOH, his laptop is known to run cooler, I just don't have any solutions right now.

My work laptop (i7-based from HP) is 40-45 C with web browsing. The wife's macbook air is <50 C doing the same. Perhaps your HSF is dusty? You'd be amazed to see that kind of junk I have removed from mine with some compressed air.

Oh, I have been amazed by the cruft found in machines. My favorite was a mouse nest in which the critter used the computer owner's missing marijuana stash. At least my friend was relieved it was not has roommate stealing it
My machine stays pretty clean. My home is hardwood (no carpets), no pets. It has always run warm. 40C is pretty darn good -- I'll bet you get a reasonable battery life.

Thanks for you answers, may be the reason in fan, but one thing that I don't understand: why turbo permanently active.

Please reread the Code of Conduct (particular attention might be paid to the section regarding necrobumping).

Closing.
