Electric heat on pine wood 

In physics, dissipation encompasses the concept of a dynamic system where important mechanical models, such as waves or oscillations, lose energy over time. The lost energy is converted into heat, raising the temperature of the system.


A CPU dissipator is a device that draws heat away from a CPU chip and other hot-running chips such as a graphics processor (GPU).  A computer's CPU works by either enabling electric signals to pass through its microscopic transistors or by blocking them. As electricity passes through the CPU or gets blocked inside, it gets turned into heat energy. ​Most desktops CPUs run in the 50-70°C (that's 122-158°F) range under load but it can easily reach up to 100°C with no major problems

The work alludes to the principles of the Second Law of Thermodynamics, which states that every energy transfer or transformation increases the disorder (entropy) of the universe, to reflect on how different sources of power grounds, transports or produces information of different kinds and to different ends, from processing immensely complex data for scientific purposes or to produce a simple pyrogravure.

To stamp the dissipator in a wood board it requires the heat produced during 45 days of regular 5 daily hours usage of the CPU operating on an average 80% of its capacity.
