Android-x86, ver 6.0, Disable cpu-fan by script or hack ?

jopema · 09-27-2018, 02:31 PM

Dear Forum.
When running android x-86 my cpu fan goes wild allthough computer is cold. As Im not doing anything advanced else than browsing and lighter calc/word editing I want to disable cpu-fan or set it permanent to 5%. Of course I should troubleshoot the lm sensor package and cpu governor but those operations usually takes a day or two and I will just not invest that time any longer, its not that fun anymore and I prefer revert back to win instead of going linux. If there is a quick n dirty simple hack for just killing the cpu fan by script at boot in init.sh or something similar I appreciate any idea. I will not pull the plug for the cpu fan as fan is needed for heavier applications in win. Im running android x86 as it always manages booting my uefi laptop without hazzle.

kindly Peter.

Only idea I can give is for you to think about installing a different kernel in your install

Quote:

There's a simple way to test a new kernel — just drop it into an existing installation of Android-x86

Citation: https://arachnoid.com/android/Androi...op%20Howto.pdf

So maybe search on how you can insert and pick from androids grub boot menu the test kernel.

My only hands on experience with what you are doing. I installed android x386 on a couple atom netbooks and then sold them to some local high school kids on the cheap.

Maybe , just maybe

Code:

sudo sensors-detect

If it runs. Say Yes to everything. lmsensors comes in most linux installs. All you might have to do is configure the sensors

https://www.linux.com/learn/intro-to...tricks-linux-0

Code:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +50.5°C  (crit = +102.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +49.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +49.0°C  (high = +105.0°C, crit = +105.0°C)

dell_smm-virtual-0
Adapter: Virtual device
Processor Fan:    0 RPM
CPU:            +50.0°C  
SODIMM:         +46.0°C  
Other:          +48.0°C

Thank you all for good advices.
Unfortunately I have not been able solving the issue.

1. "sudo sensors-detect" gives "not found" (as did "su" and "sudo"), just "sensors-detect" gives "unknown id". If Im remember right from ten years ago I think Im su if bash is $ right ?
2. Changing kernel is way above my level, I need to use the software and dont have time nor interest tinkering with such big task.

The android-x86 is a wonderful dist with the whole android app world available so any idea and suggestion is highly appreciated to fix the runaway fan issue.

Kindly Peter.

do you have android_x86 installed to your PC?
while it is technically Linux, the advice given here probably doesn't apply.

there's an even bigger problem:
Android is built for very different hardware.
android_x86 attempts to make Android usable on your PC, but it probably cannot recognize all the hardware & act accordingly (or have you ever seen an android phone with a fan?).
tbh i never even considered running android_x86 on bare metal. i used to have it in a vm for some very special cases.

tl;dr:
install some real gnu/linux!

I've attempted to manually control fan speed, but I never succeeded.
