Air-cooling for the CPU is undoubtedly one of the easiest and most cost-effective upgrades that one can make. In this vein, even a casual perusal of aftermarket heatsinks available around the web will illustrate that most of the more popular enthusiast coolers are quite large and their design does little to cool the components surrounding the socket. There's no doubt that some coolers of this design work very well, but what about a user who just wants “better than stock” cooling and doesn't have the desire, or room, for a tall tower cooler? Zalman may have just the cooling solution for these folks.
Ever since they started, Zalman has been marketing efficient, innovative cooling solutions with an emphasis on quiet cooling. With their CNPS8700 LED CPU cooler, they seem to have taken some cues from their wildly popular “flower” coolers of the past, added a heatpipe or two, and come up with a short, relatively compact cooler that could prove to be just what the doctor ordered for HTPC and other users wanting a compact, quiet cooler with good performance. Let's have a look.
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
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 to 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.
