Issue with lm-sensors

antonstenaxel · 10-02-2018, 01:13 AM

Hello!

I am trying to get some control over my fans since the noise is deafening. I'm running Ubuntu 18.04.1 and when i run ''sudo sensors-detect'' and enter my way through the prompts it outputs:

Code:

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

The link referenced to doesn't work for me, and by now I've exhausted all links on the subject on google without success. I'm running on a Asus B450-I motherboard, with a CPU-fan and two case fans hooked up to PWM.

If I run sensors it outputs

Code:

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +29.8°C  (high = +70.0°C)

asus-isa-0000
Adapter: ISA adapter

so it apparently finds something? I'm lost for ideas, any help would be appreciated!

Give this guide a try. It should help.

I'd tell you more but I've never had to use lm sensors. Sorry:-

Try with a live iso to rule out distro-specific madness.

Few distros that have lm-sensors/sensors Out of the box (or out of the live Iso anyway!) are - Manjaro, Blackarch, and systemrescuecd.

Make sure you have the latest lm-sensors package. I can confirm the lm-sensors.org website is down since about May 2016. This might help: https://wiki.archlinux.org/index.php/lm_sensors Apparently there is no list of supported devices. The team advises running sensors-detect. If it doesn't find sensors, you have unsupported sensor chips.

also make sure which fans are actually generating that noise!
it could be the PSU.
it could be a cheap GPU with a fan that cannot be regulated.
