|
|
Hello
I have a problem with the fans. It always work, even though there isn't a justification for it (at least in my opinion). Just for simple browsing and shell (even when not running emerge). The temperature sometimes reaches 90 C. It's a new laptop with a good cpu. I would like to understand what's wrong, how can I control it, improve, tweak.
Here are some settings about acpi:
Code: | grep -i acpi /usr/src/linux/.config
# Power management and ACPI options
CONFIG_ACPI=y
CONFIG_ACPI_SLEEP=y
# CONFIG_ACPI_PROCFS is not set

I have lm_sensors installed. |

If the temperature is reaching 90C, then there is definitely justification for the fans to be running at full speed. In my opinion, that temperature represents a serious failure of your cooling system. I have never seen a well maintained laptop get that high even under extended CPU load with all cores running at full. |

I ran only once with all the 8 cores (4 cores x 2 threads). And it was full load. That I can understand. I don't have history of the cpu load. Will start to check more. It just puzzled me that once I turn the laptop on, the fan starts working. It's not normal.
Right now the temp is 73C/78C (93%), the fans are running (since I booted). All I do right now is some browsing, ftp (writing to disk). Nothing special. Is this temp normal? As you can see below it's just 2.2% usage.

So, maybe I have some misconfiguration with acpi or something else? I want to run in 2 weeks the gpu, which really requires intensive work. I wonder what will happen to the temp then. I would like to solve this issue. The kernel configuration is OK?

I would not consider that temperature to be normal. I believe mid-70s was achievable on my last laptop only when I ran a long running emerge that held all cores at full usage for several minutes. |

What does "zegrep 'CPU(FREQ|_IDLE)' /proc/config.gz" say? |

As I can see from cat /proc/cpuinfo in the Power Management there are no parameters. Is this ok? Should I set something? |

How you are managing the frequency? |
Well, I didn't. I wasn't aware of it at all. I am noob on these points. Will set it. Are there more things that I need to set? |

Ok. I did that. It turned out that it was already selected. I removed only the userspace governor and conservative cpufreq governor.
rebooted into the new kernel.
Yet the fan still works all the time, even when the laptop was cold.
Probably the problem is in other place. Any ideas where?
Also I see that max temp appears to change. I don't know why this happens. Right now it shows 70C/80C. Other times it shows 56C/68C. Why is that?
I think that acpi doesn't work properly. I can't believe that after 8 hours of shut down the temp showed me 56C. |

I think it is not a fan or kernel acpi options issue.
At first you have to check: may be radiator is not tight to the processor.
At second, it may be sensor failure. This case fan will rotate at high speed even CPU itself is cool. The fact, that fan starts at high speed, indirectly confirms this.
Any way you need to remove the cover and make sure whether the CPU temperature so high or not.
Of course, you need to have some basic experience in NB disassembling. |

I opened few times an older laptop. This laptop, I didn't open yet. It's just 1 year old. Will open it at some point, to clean also the dust that probably piled up.
How can I check sensor failure?
My indication that acpi doesn't report correct the temp because the laptop was shut down 8 hours. There is no way in the world that immediately after boot, I get 56C and the fan start to work. I have in the kernel set cpu overheating reporting set. I never got an alarm that cpu is overheated.
Yet, the air that goes out of the fan is to some extent hot. I have a friend that has windows with exactly the same laptop and the fan doesn't work all the time.
This is the output of sensors-detect
Code: |
cat /etc/conf.d/lm_sensors
# Generated by sensors-detect on Wed Sep 25 17:49:34 2013
# This file is sourced by /etc/init.d/lm_sensors and defines the modules to
# be loaded/unloaded.
#
# The format of this file is a shell script that simply defines variables:

# Initialize sensors at startup

HWMON_MODULES="coretemp"
# For compatibility reasons, modules are also listed individually as variables
# MODULE_0, MODULE_1, MODULE_2, etc.

# steps of 1. Any number that is missing will make the init script skip the
# rest of the modules. Use MODULE_X_ARGS for arguments.
#
# You should use BUS_MODULES and HWMON_MODULES instead if possible.
MODULE_0=coretemp

Remove a cover and touch CPU. Is CPU really hot, as shown in BIOS? Btw did you checked what a temperature shown in BIOS? It is far more important indicator than the temperature shown by lm-sensors.

Can you explain, what did you meant when you've written "boot"? Is it a system boot? If yes, CPU is quite likely to heat up to 56C during OS boot, especially if it has a bad thermal contact with a radiator.
If you meant "immediately after power on", the only reason of this is sensor failure.
Anyway, the only thing that can help to determine where a problem came from is checking for real CPU temp.

if your friend has the same laptop, does it guarantees that your laptop never will fail? |

Will check in the bios.

I meant after boot of the OS.
I read now the acpi gentoo guide. Do you suggest to use cpufreqd? |
