my computer is prone to over-heating and so I'm trying to control the fan speeds. I've researched a little and I'm blocked How to control fan speed? and then installed lm-sensorsand fan control.

I'm now trying to configure lm-sensors to no avail. In terminal I typed sudo sensors-detect and answer YES to all YES/no questions. Installed modules with sudo /etc/init.d/kmod start. Now when I type sudo pwmconfig I get this output

     /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

The way I tried to fixed this is to edit /etc/default/grub to add acpi_enforce_resources=lax to the GRUB_CMDLINE_LINUX_DEFAULT and then perform a grub update. I'm still having the same issue. This is the output of the sensors command.

Core 1:         +45.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:         +46.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:         +44.0°C  (high = +84.0°C, crit = +100.0°C)

Can anyone help me? Thanks.

It appears the fans inside the computer are not PWM or Pulse-width modulation.

Common cooling fans used in computers use standardized connectors with two to four pins.

PWM use a 4 pin connector and can be controlled by software.

The first two pins are always used to deliver power to the fan motor.

3 pin connectors don't have PWM 3-pin fan speed is controlled by voltage.
