at what fsb should i be concerned about cooling my nb on my ds3 in a better manner? if it helps my ambient temps are fine (room is air conditioned around 65c) and i have adequate case cooling, 120mm intake, 80mm intake, 120mm exhaust, and an ultra-90 heatsink. i'm currently running a presler at 14x287 and its barely warm to touch and i am going to replace it with a e4300 hopefully at 3ghz and higher.
