NOCTUA NC-U6 CHIPSET COOLER INTRODUCTION
Modern CPUs seem to be on a downward trend when it comes to heat production. This is not the case when it comes to motherboard chipsets. They are running as hot, or hotter than ever. In this review we'll be looking at a recent offering from Noctua, an Austrian company that has been around for some time. Their NC-U6 chipset (or Northbridge) cooler uses copper and aluminum components in conjunction with heatpipe technology to produce a small tower cooler that may alleviate the chipset cooling woes of PC enthusiasts looking for improved performance and/or reduced noise. Let's have a look.
NOCTUA CORPORATE PROFILE
Noctua aims at establishing a new level of quality and performance "Designed in Austria" through paying attention to the users' needs in a market burdened with all kinds of frills and furbelows and providing sound-optimised premium components, which serve their purpose in a smart, precise and reliable manner.
SMALL HEATPIPE TECHNOLOGY TUTORIAL
I am going to keep this as simple as possible to get the basic premise across to all of the Tweaknews readers. Please don't be insulted if this is too simple for your education level. I have to cater my writing to the least technical reader looking for information.
The basic idea behind heatpipe technology is really simple.
1.) With a tube containing a compressed fluid/gas, the fluid comes in contact with the heat source (the CPU core, in this case) which heats up the volatile fluid and turns it into a gas. The energy is absorbed in the gas production process and is ready for transportation.
2.) The heated gas now travels along the inner portion of the tube where it comes to the cooling portion of the heatsink in this example.
3.) The radiator, with or without a fan, will cool the liquid and transfer the energy (AKA heat) to the radiator to be dispersed to the surrounding air. With the heat removed, the vapor quickly condenses back to a fluid and runs along the inside surface of the pipe back down to the bottom where the process can be started all over again.
For another example, you can consider a boiling pot of water with a glass lid as a very basic heatpipe. When the water boils, the water vapor comes in contact with the cooler glass pot lid which forces the vapor to condense back to water where it dribbles back down the inside of the lid back into the pot.
It's basic, but it gets the point across.
