Prevent Your Laptop From Overheating With Thermald And Intel P-State: http://www.webupd8.org/2014/04/prevent-your-laptop-from-overheating.html
Linux Thermal Daemon (thermald) is a tool developed by Intel’s Open Source Technology Center which monitors and controls the CPU temperature, preventing it from overheating.
Thermald tries to prevent the CPU from overheating without a significant impact on performance by using some specific Intel functions available in the Linux Kernel.
It’s worth mentioning that thermald applies various cooling methods only when the temperature reaches a certain threshold, so you may not notice a difference while using it if your laptop doesn’t usually get very hot.
