My processor is nice and cool thanks to the cooler! I do not think the difference would be such but I from 40 ° to 20 ° C in idle Right in the games I never exceeds 60 ° (which is quite good for this processor) Overclocked to 4.3Ghz (4.5Ghz see) I never exceeds 70 ° c! Excellent for a small cooler (probably will return in all builds) Make all the same attention to dimensions.
