- Set to max:
i8kfan 2 2
- But right after you set it the bios puts it right back down? (Run the command fast in a row)
- To fix, we need smm
wget https://launchpad.net/i8kutils/trunk/1.42/+download/i8kutils_1.42.tar.xz tar xvf i8kutils_1.42.tar.xz
- Build smm
cd i8kutils
- 64 bit:
gcc -g -O2 -Wall -I. -o smm -m32 smm.c
- 32 bit:
make
or
gcc -g -O2 -Wall -I. -o smm smm.c
same thing
- Disable BIOS Fan Speed Control:
sudo ./smm 30a3
- Enable BIOS Fan Speed Control:
sudo ./smm 31a3
Disable it and issue the command again!
i8kfan 2 2 (Listen as this will set fans to maximum speed)
i8kfan 1 1 (This will set fans to slow speed)
i8kfan -1 0 (which means there is no left fan and the right fan is off)
i8kfan - 1 (turns the right fan on at the minimum level)
i8kfan - 2 (turns the right fan at the maximum level)
i8kfan - 0 (turns the right fan off)
