Would having the onboard graphics turned on and having a graphics card in the slot make the cpu work harder.Reason why im asking i have run my new build in bios no windows installed yet and after 10 mins my cpu was about 49 degrees and the cpu fan was running at 4000 rpm so i turned it off.I do have 2 case fans but 1 isnt working yet as i need an adapter for a 3 to 4 pin and none localy will have to send off.
