i built my machine at the beginning of the year and chose the ultra 120 because of reviews over the scythe. the ultra 120 having less surface area would make you think it wouldnt cool aswell but it did it better.

the one i have has only 4 heatpipes (if only i waited a month for the ultra x) but after lapping it and the processor im getting temps of 19-22 degrees idle.

i think manufacturer's should spend more time on the cpu contact surface instead of more metal & more elaborate fins / layout. the extra weight isnt great either, watch them sag in a tower case!
