-====== 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:
-<code bash>
-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
-</code>
-By turning off Turbo Boost, my CPU fan speed floats around 4000 RPM.
