I've just done what you've advised me and ...already my CPU is cooling
down...but I've noticed the following: sensors only detects my CPU
sensor(souldn't there be others?, and yes I've ran sensors-detect), I
can;t seem to be able to to start fancontrol because pwmconfig can't
gind any pwm sensors. Also on you config I seem not to be able to
change my Cpu's freq with kLaptop.Thanks for the help so far!
