• Resumen

  • As Pentium-IV, a high-performance PC CPU, emerges, CPU’s thermal design power shows sharp increase. Since conventional cooling method, aluminum extruded heat sink has disadvantages like poor cooling performance, acoustic noise increase and weight rise, cooling module in the form of remote heat exchanger using heat pipe is developed. Especially, using system fan exhausting heat inside to cool CPU reduces acoustic noise with lowered quantities of fan and makes it possible to reduce manufacturing unit price. This paper proposes cooling using heat pipe, recommends Pentium-IV CPU cooling module on change of fan revolution speed, and looks for possibility of reducing acoustic noise.
