Turning off Intel Turbo Boost(TM) on Linux
My laptop is a Lenovo T440p with a i7-4900MQ. I run Folding@Home on two of my CPU cores. The CPU constantly overheats, and my fan is always spinning at 4440 RPM. I find the noise annoying. So here is what I do to control Turbo Boost:
fangfufu@illustrious:~$ cat /usr/local/bin/turbo-boost #!/bin/bash echo "Intel Turbo Boost(TM) Status:" if [[ $1 == "off" ]]; then echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo fi if [[ $1 == "on" ]]; then echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo fi state=$( cat /sys/devices/system/cpu/intel_pstate/no_turbo ) if [[ $state -eq 1 ]]; then echo "Off" else echo "On" fi
By turning off Turbo Boost, my CPU fan speed floats around 4000 RPM.
