How to add sensors and cooling devices to thermal-conf.xml

I have a Toshiba NB510-108 netbook with Xubuntu 14.10 installed. Under Windows 7 Starter, temperature sensors show values up to 45 degrees Celsius. Under Xubuntu, they show values up to 55 degrees. I would like to use thermald to keep the temperature at 38 degrees. My thermal-conf.xml file only contains one sensor of type TSKN and two cooling devices of types rapl_controller and intel_powerclamp. sensors -u shows this user@user-TOSHIBA-NB510:~$ sensors -u acpitz-virtual-0 Adapter: Virtual device temp1: temp1_input: 42.000 temp1_crit: 110.000 coretemp-isa-0000 Adapter: ISA adapter Core 0: temp2_input: 43.000 temp2_crit: 100.000 temp2_crit_alarm: 0.000 Core 1: temp3_input: 43.000 temp3_crit: 100.000 temp3_crit_alarm: 0.000 Can anybody please tell me how to add the above sensors to thermal-conf.xml, and maybe also how to locate and add other cooling devices?
