Intresting. I've never heard of something like this before. It sounds like a new gadget for me to buy!

How much was the heatsink?

"The magic of a phase change system comes from the substance used to transfer the heat from one place to another, namely the refrigerant. This magic is due to a property called latent heat of vaporization. This technical-sounding term can be reduced to a very simple concept - a good refrigerant absorbs a huge amount of heat as it changes from a liquid to a gas (or changes phase). Think of it in terms of an aerosol can. Have you ever been using a spray can and felt the can grow cold as it was sprayed? That's a small example of a refrigerant in action. As the can is used, the pressure inside drops, the liquid propellant evaporates, absorbing heat, thus the can grows cold.

Chemists have long known that one of the best refrigerants is a CFC (chlorofluorocarbon) based substance commonly known as freon. However, what these chemists understood only later, and to the detriment of everyone, is that CFC based refrigerants are absolutely horrible for the environment, particularly the ozone layer of Earth's atmosphere. They went back to the drawing board and have, over the last 15-20 years, worked on developing non-CFC refrigerants that work as well as good old freon. An example of this newer breed of refrigerant is R134a, which is used in many refrigeration and air conditioning applications. In the case of the Vapochill LS, its system is designed to use either R404a or R507 refrigerant, which are variations on the same theme (R404a is actually a blend of several refrigerants, including R134a)."

Using a gas to help power a fan, then turning it back into a liquid, heating the liquid, and continuing the process over and over again?

It sounds like a cool idea (pardon the pun), and I can see why it would be so effective and expensive!

The gas you explained about sounds very much like nitrogen or hydrogen... I would say nitrogen because it turns into a gas on contact with the air, and also it's environmentally friendly.

"Dear Mr. Thomas,

We would like to greatly thank you for your interest in ZALMAN.

However, we cannot provide people with information regarding the exact ingredient/substance for the coolant inside ZALMAN heatpipes.



We hope you understand why we cannot do so J

Best Regards,

Support/ZALMAN"

This is the lame reply I got from the Zalman's rep;

So basically I didnt get any more information than I already had
