Intel's thermald prevents machines from overheating and has been recently introduced in the Ubuntu Trusty 14.04 LTS release. Thermald actively monitors thermal sensors and will attempt to keep the hardware cool by modifying a variety of cooling controls:
* Active or passive cooling devices as presented in sysfs
* The Running Average Power Limit (RAPL) driver (Sandybridge upwards)
* The Intel P-state CPU frequency driver (Sandybridge upwards)
* The CPU freq driver* The Intel PowerClamp driver
Thermald has been found to be especially useful when using the Intel P-state CPU frequency scaling driver since this can push the CPU harder than other CPU frequency scaling drivers.
Over the past several weeks I've been working with Intel to shake out some final bugs and get thermald included into Ubuntu 14.04 LTS, so kudos to
