#StackBounty: #linux #google-chrome #cpu #fan #task-manager How to track down what's "melting" my laptop – spinning the fan

Bounty: 50

Problem:

CPU fan spins at random times.

Why it’s a problem?

Linux laptop is sitting in my room. Unused by me. Spins fan in irregular moments (probably using lot of CPU). Sometimes couple of seconds. Sometimes a few minutes. Then quiet again. A minute or few later fan noise again. The noise is very annoying. If I forget to turn laptop during night it wakes me up.

What I’m Asking?

Please tell me how to track down what uses CPU and spins the fan.

Is there a tool which would record in time what was using lot of CPU? Ideally also when was fan spinning? I would like to let that tool running for a while and then look at the data collected and find the root cause (or multiple).

What I already know?

I know tools like top or htop for linux processes. If I’m staring at them I can kind of guess what could be the reason, but it’s difficult and could be incorrect guess. When Chrome browser is likely to blame, I need to go to Chrome Task Manager (tree dots menu->More Tools->Task Manager), the same problem. I need to stare for long and guess what could be the issue.

E.g. If the process is really Chrome, and there is one stupid tab which needs to use all my CPU for whatever reason I can just make sure I close it when not needed. Or I can stop using that site, but I need to find out which webapp (chrome tab) it is. If it’s not a chrome, but another linux process, I will know if it’s legitimate use or if I can close it. Alternatively reduce priority or somehow else convince the process not to use all the resources at random times.

#StackBounty: #18.04 #lenovo #overheating #fan #temperature Lenovo Y540 overheating issue

Bounty: 50

I have recently increased the size of my Ubuntu /home directory and reinstalled both Windows and Ubuntu on my Lenovo Legion Y540 laptop. Installation went smooth, but after all of it I have noticed that my Laptop gets significant heat (palpable on keyboard) even when simple web browsing. I have installed lm-sensors to check for the temperature of my CPU and straight after booting Ubuntu, temperatures were as follows:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +66.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +66.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +64.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +66.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +63.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +63.0°C  (high = +100.0°C, crit = +100.0°C)
Core 5:        +62.0°C  (high = +100.0°C, crit = +100.0°C)

At the time of writing this post I have only a dozen or so Firefox tabs enabled and the temperature are as below:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +85.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +85.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +79.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +85.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +81.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +85.0°C  (high = +100.0°C, crit = +100.0°C)
Core 5:        +81.0°C  (high = +100.0°C, crit = +100.0°C)

Therefore, I am concerned to do any computing as those temperatures would certainly go even higher. I have this laptop for about 6 months and I didn’t observed this significant keyboard heat before. Any ideas what may be causing this issue and what should I change to prevent it?

I’ll be happy to provide any additional information.

@Edit: I worked on Windows for a couple of minutes. I don’t know how can I measure the CPU temperature on Windows, but palpably, the issue was absent there.

@Edit2: I switched to Intel GPU as advised by @heynnema, the current output of sensors is:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +84.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +76.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +75.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +85.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +76.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +80.0°C  (high = +100.0°C, crit = +100.0°C)
Core 5:        +77.0°C  (high = +100.0°C, crit = +100.0°C)

Where as the output of ps auxc | grep -i therm. is:

root       210  0.0  0.0      0     0 ?        I<   cze07   0:00 acpi_thermal_pm
