You may need to reapply your thermal paste. Go to SLS (Or your closest Cyberactive store if got no time to go to SLS) to buy a tube of thermal paste if you do not have one.
Also, go to Guardian to buy a bottle of isoprophyl alcohol and use this to wipe off any residue of old thermal paste. You must wipe off all old thermal paste before applying any new thermal paste, otherwise the new thermal paste will not conduct heat properly.
After you have settled your heat issues, then you can go to the Bios and slowly turn down your fans until it is quiet.
