ZALMAN CNPS9700 LED INTRODUCTION
The CPU cooler wars have really been heating up lately. Armed with heatpipe technology, cooler manufacturers have come out with some very interesting products to keep CPU temperatures in check. Zalman, one of the leaders in the high-performance, low-noise cooling niche, has recently released their CNPS9700 LED cooler into this highly competitive market. Basically this is an updated version of their very popular CNPS9500 cooler (see the TweakNews review HERE .) It's a bit larger than its predecessor and uses a 110mm cooling fan (versus the 92mm fan used in the CNPS9500.) Let's take the 9700 for a spin and see if it earns a place in the market and on your motherboard.
ZALMAN CORPORATE PROFILE
Despite the fact that computers have become commonplace at home and at workplaces for a long time, true user-friendliness of the computers is still a long shot. At Zalman Tech, we strive to make that goal a closer reality through extensive research and development of our products. We were the world first in reducing computer's noise down to lower than 20dB, thus creating a more user-friendly computing environment. Now it is possible to use a computer without distracting noise and to form high fidelity audio system or home theatre without ambient noise.
Zalman Tech will continue to make efforts at creating more enhanced levels of user friendliness in computing; we believe that we have the ability and determination to achieve this goal. Your support and interest is greatly appreciated.
SMALL HEATPIPE TECHNOLOGY TUTORIAL
Let's 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 basic for your education level, we're just offering the basics 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 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.
