ZEROTHERM BTF95 INTRODUCTION



CPU coolers have got to be one of the largest subsets of the PC aftermarket, in terms of units sold. There are a few manufacturers that always seem to lead the pack when it comes to cooling performance, and users seem to have less brand loyalty than in most other segments of the market. The silent computing crowd not only wants cooling performance, but the cooler has to be quiet, as well. As processors become more efficient, they generate less heat than their predecessors. This time out, we'll be testing a fanless cooler from a relative newcomer, Apack. Their ZEROtherm BTF95 cooler promises “Killer Performance” and “Silence Innovations”. The BTF95 is about as quiet as you can get, having no fan at all, but is it up to the task of cooling modern, mainstream processors? Let's see.

 

ZEROTHERM CORPORATE PROFILE


APACK is a heatpipe technology based thermal solution provider which provides customized designing and engineering solutions and, ultimately, provides best-of breed thermal solutions.


APACK's design and manufacturing is based upon an engineer's passion for innovation and progress. APACK was established in 1999 by 3 engineers from ETRI (Electrics and Telecommunications Research Institute) who have 10~17 years experience in thermal solutions and advance packaging technology (packaging referring to the structural and functional integration of multiple technologies). Based in the city of Daejeon (Korean Silicon Valley and high-tech capital), APACK is staffed with top engineers who have extensive experience.


APACK is currently entering into its second phase of business development after accomplishing its first goals of developing a strong R&D core in thermal technology and efficient manufacturing capabilities. Phase one was marked by strong revenues and growth in the OEM and custom solutions market producing for such clients and Samsung, Dell and LG.


Backed by investors such as Intel Capital, a strong backbone of R&D with continued cooperation with ETRI and APACK is seeking to become a global player in the thermal solutions market.

 

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 is dribbles back down the inside of the lid back into the pot.


It's basic, but it gets the point across.
