That it reports 10c higher is becouse tjunction is set to 105c instead of 95c as it "should" be.

its not THAT weird that its coming some sounds from your components, probably its your psu, i dont know the word for the component in english that makes the sound, its those small things with copper wired around them, sometimes, when they are bad insulated, or are toughing something thats beside it, they make small vibrations during heavy load, this is very annoying and if you have this problem you should RMA your psu or whatever is making the sound, almost all hardware have this component. But its mostly common that its the psu or vga card, when you're making load the them.
