I am using a ThinkPad X201 with Debian (Wheezy) and LXDE. The laptop is very hot even without heavy load. Now, the load of CPU with a top command: load average: 0.04, 0.12, 0.13, But the temperature is 55o C. I opened the laptop and checked the fan. It is not so dirty. I am sure that there is no any large software running. Can anyone can help me to fix it?

The output of sensors in my system is:

 Adapter: Virtual device
 temp1:        +54.0°C  (crit = +100.0°C)

 Adapter: ISA adapter
 Core 0:       +51.0°C  (high = +95.0°C, crit = +105.0°C)
 Core 2:       +48.0°C  (high = +95.0°C, crit = +105.0°C)

 Adapter: ISA adapter
 fan1:        3265 RPM
 temp1:        +54.0°C  
 temp2:         +0.0°C  
 temp3:         +0.0°C  
 temp4:         +0.0°C  
 temp5:         +0.0°C  
 temp6:         +0.0°C  
 temp7:         +0.0°C  
 temp8:         +0.0°C  

This is the lowest temperature under normal use.

    OK,perfect, your temperatures are half what would be considered a dangerous temperature. Everything is fine, your computer is not hot, it is running at a very normal temperature. Everything is OK :) – terdon Sep 13 '13 at 0:18
  • While it's true that those temperatures are fine, I'm wondering if the whole Intel Speed Step thing is working for you. This would also explain some of your battery drain. – Brad Sep 13 '13 at 1:17

55 is not that hot, sounds fine to me actually. 55 is about the lowest temperature I ever see on my Dell.

One way of checking what the critical (the dangerous) temperature is for your CPU is sensors (the output shown is what I get on my Dell with an i7 processor):

  • First, install it and detect available sensors

    $ sudo apt-get install sensors
    $ sudo sensors-detect
  • Then run it

    $ sensors
    Adapter: ISA adapter
    Core 0:       +56.0°C  (high = +95.0°C, crit = +105.0°C)
    Core 2:       +55.0°C  (high = +95.0°C, crit = +105.0°C)
    Adapter: Virtual device
    Right Fan:   87240 RPM
    CPU:          +54.0°C  

    That tells me that the CPU is considered hot after 95 degrees and will shutdown to avoid damage at 105, that's twice what you're experiencing.

  • @HXGuo please add the output to your question (edit it) not to the comments. – terdon Sep 13 '13 at 0:12
  • I have updated my question. Is the temperature not hot? The battery of my laptop only can use in 30 min. – HXGuo Sep 13 '13 at 0:16
  • @HXGuo no the temperatures are not hot, not even a little bit. If the battery only lasts for 30 mins, that is a different problem. PLease post a new question about that. – terdon Sep 13 '13 at 0:19
