Many computer motherboards still cool their chipsets with a standard aluminum heatsink and a small fan. While these may work fine at first, the fans tend to break down or become noisy, or just aren't sufficient when overclocking. Motherboard chipsets are running hot, especially since more northbridge chipsets are taking on additional tasks like audio and video processing. There are several third party chipset coolers, all with varying degrees of pros and cons. Some are just as bad as the OEM heatsinks, while others offer extreme cooling while remaining virtually or completely silent.
Noctua is aiming to deliver high quality computer products and proudly proclaim their products are "Designed in Austria". Their answer to the chipset cooling problem is the Noctua NC-U6 chipset cooler, which is a high-rising copper and aluminum heatsink with heatpipe technology that looks rather impressive.
