LG notebooks stay 'cool' with CNT technology

Described as a 'sub-notebook' due to its compact size, the TX Express weighs just 1.1kg, has an independent graphics card (NVIDIA GeForce Go 7300) and yet remains stable against heating thanks to its novel CNT cooling system.

The cooling fan of the TX Express Series is coated with CNT, which is the product of 12 months of research at Korea's Institute of Advanced Aerospace Technology.

Tests on the TX Express show that CNT decreases heat emissions by more than 10 per cent compared to ordinary notebook PCs, and it reduces heat in the CPU and graphics card by up to three degrees Celsius.

C.H Lee, President, LG Electronics Gulf FZE, said:

"Heating problems have surfaced with today's proliferation of super-slim notebook PCs, and this is an urgent issue that needs to be addressed by PC makers. Through the TX Express and CNT technology, LG has once again proven its leadership for innovation."

Since notebook PCs are compact devices without the large and robust heat sinks and fans of desktops, they are usually restricted in adopting high performance components such as a CPU with high clock speed and discrete graphics card.

Due to thermal issues, thickness and performance of a notebook is a trade-off. In order to make the main body of the notebook slim, the graphics card is typically shared to generate less heat. If a notebook PC is equipped with a high-performance discrete graphics chipset, its thickness and weight are normally increased to allow sufficient heat release.

Lee added: "CNT technology allows LG to rewrite the rulebook for notebook PCs. LG has focused resources and capabilities on research and development, and is investing US$2.64 billion in R&D going forward."
