+ | ====== 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: | ||
+ | #!/bin/bash | ||
+ | echo "Intel Turbo Boost(TM) Status:" | ||
+ | if [[ $1 == " | ||
+ | echo 1 > / | ||
+ | fi | ||
+ | if [[ $1 == " | ||
+ | echo 0 > / | ||
+ | fi | ||
+ | |||
+ | state=$( cat / | ||
+ | if [[ $state -eq 1 ]]; then | ||
+ | echo " | ||
+ | else | ||
+ | echo " | ||
+ | fi | ||
+ | |||
+ | </ | ||
+ | |||
+ | By turning off Turbo Boost, my CPU fan speed floats around 4000 RPM. |
