I'm using a 32-bit Linux Mint Rosa 17.3 with MATE DE (for the record, the same issue exists on a 64-bit flavor as well, and I have had this issue with every ubuntu-based distro). It is installed on a Fujitsu Siemens Amilo Laptop with 2GB RAM. All updates are installed.

The problem is, there is no fan control, either actively or passively. That is, I have no way of controlling the fan speed, and the system doesn't control it either. It's always running at a constant, high speed. There are no overheating problems (temperature monitors are working and report temps at ~58-60C). But the noise is bothering me.

What I have done:

1) lm-sensors is installed.

2) I have run sudo sensors-detect, without anything happening (i.e. it doesn't detect any fans, I only get this:

#----cut here----
# Chip drivers
coretemp
#----cut here----

Here's the output of sensors:

acpitz-virtual-0
Adapter: Virtual device
temp1: +50.8°C (crit = +109.8°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +48.0°C (high = +100.0°C, crit = +100.0°C)

Here's the output of inxi -Fxz

What's going on here?

For the record, the laptop fans worked fine (i.e. they are detected and are controllable) when using Windows Vista (also installed)

  • I have the same problem on a desktop with a Fujitsu motherboard. Same output from sensors-detect and sensors, and inxi also says Fan Speeds: N/A. I don't know anything specific about Fujitsu mobos/support (yet), but at first glance it appears that linux or lm-sensors don't include drivers to read the Fujitsu fan controls. If this is correct, the question remains if there are any compatible drivers out there somewhere. – JanKanis Jun 22 '19 at 8:58
