your temps are normal ban( in the room temp in SL but this is not good for cpu's life span)... i have also suffured from this problem in my C2Q q9505 too...i tried arctic silver also it reduced 1c in idle and 5c in load... please post ur idle temps.... then i can suggest you a option.. as i know when the default bios settings are set.. your core temps can go upto 100c ...
Ideal temps menna machan,
then it must be overheating or ur PSU isn't enough with ur VGA....
so as u said if it goes over 80'C which means ur cooling sys is not good even though u have 3 fans inside ur casing.. try to cean ur cpu fan
if it still goes over 70'C i guess u will have to change ur fan....
