Fujitsu has unveiled plans to use carbon nanotubes in PC heat sinks, the first time that the high tech material has been used in PC design.
Carbon nanotubes, a form of carbon that is stronger than diamond but flexible and extremely conductive to heat, will allow processors to run at much higher frequencies and temperatures than is currently possible.
Today's processors are limited to running at around 4GHz before heat build-up becomes too intense.
"Fujitsu's new technology enables the simultaneous achievement of high amplification and heat dissipation in high-frequency, high-power amplifiers," said the company in a statement.
"Fujitsu has succeeded in the world's first application of carbon nanotubes, which have excellent thermal conductivity."
The firm hopes that the new heat sinks will enable chips to run at speeds of 5GHz and beyond. In addition the nature of the material will allow for much smaller heat sinks that can be used for mobile computing.
