I think that the CPU is working harder with the dedicated graphics and that's why you are seeing the heat problem.

I would first check that the cooler is snug and the fan is spinning as it should be.

If so, I would pull the cooler and repaste the CPU.

I would also run with the case open just to see how much that got me.

i3 540 can handle gts450 fine.. gts450 is middle range card.. Today i cleaned my gpu.. now gpu temp is about 40°C to 60°C while gaming.. but cpu temp is problem.. its go around 105°C while gaming.. my psu is dual rail 12v.. 12v 1-18A 12v 2 -18A.. this cause this problem?? Because when i unplug gpu everything is fine.. gpu consume lot power i think..my gpu is 6pin gpu.. how can i solve this?? Plz help anyone..
