"The new version 2.18 includes more than 80 significant improvements, however, we expect that CS 2 users will mainly appreciate possibility to move relationship lines and add break points", says Vaclav Frolik. With this feature, Charonware wanted to respond to its customers' needs.

To get practical insight on how to work with CASE Studio 2 and its newly added features, Charonware offers very helpful instructional movies on its website. Other useful documentation like CS2 White Paper and manual are also available.

Finally, to consider whether CASE Studio 2 meets customer's requirements and runs without any problems, it is possible to test CS2 demo version. Charonware provides time-unlimited, free demo version and at same time free email support.

"Charonware provides highly professional and customizable, smoothly integrated database modeling and reporting tool at unmatched price. Our aim is to make software products that would be beneficial for database designers, developers and all who want to accomplish all their database-related tasks with greater productivity and higher quality," concludes Vaclav Frolik.

If we move air away from heat sink, it will take heat energy with it. A fan mounted on heat sink is used to move air. This method of heat transfer is called convection. Eventually all air inside computer case will get hot, so fans are used to blow air out of case of computer.

The heat has moved from CPU, to heat sink, to air inside case, to air in room where you're sitting at your computer desk. The room starts to get hot, and eventually air conditioner turns on.

You can view an air conditioner as a "pipe". A fan blows hot air from your room through fins that transfer heat to a liquid. The liquid is piped to fins outside house. A fan blows cooler outside air past fins to remove heat from liquid.

The air conditioner has an evaporator valve that changes liquid to a gas after heat is removed. In a gas, molecules are further apart than in a liquid. This causes it to cool down quite a bit more. The gas goes through fins inside house, picking up heat. It is then compressed into a liquid to concentrate heat so outside fins can remove heat more efficiently.

Shuttle's I.C.E. (Integrated Cooling Engine) Heat Pipe uses a very similar method to cool a CPU. The CPU has a heat sink with copper heat pipes. The heat of CPU causes liquid coolant inside heat pipe to change to a gas. Convection created by pressure of gas moves coolant to a second heat sink where a fan is used to blow heat out of computer's case. Releasing heat causes coolant to change back to a liquid. Gravity then carries coolant back to CPU heat sink.

One last method of heat transfer we haven't discussed yet is radiation. Some of heat of CPU and heat sink is released as infrared radiation. Similar to light (although invisible to human eyes), radiation strikes insides of computer case, causing it to get warm. Ultimately computer case itself acts as a heat sink conducting heat to outside air.

This article explains three ways - conduction, convection, and radiation - that heat is transported from a computer CPU to air outside computer case. You now understand thermodynamics of a computers and why it is important to maintain its various components.
