Can you hear it? Silence, that's one of the calling cards for the Noctua NC-U6 chipset cooler we will be looking at today. This chipset cooler features heatpipe cooling, 29 aluminum fins, soldered connections and you guessed it, no fans. With today's hot-running chipsets, the stock cooling is marginal at best. For those who want to reach for and achieve the highest possible clock speeds, replacing the chipset cooling with something better is not optional - it is mandatory.
